Question 1. Use your textbook to measure the length of the following objects.
Objects: Desk, Blackboard, Window
Answer: When you measure these items with your textbook, you will get different lengths depending on your textbook's size. The desk is roughly 32 cm long, the blackboard is about 78 cm long, and the window is approximately 22 cm long. These are example measurements - your actual results may vary based on your textbook's exact dimensions.
In simple words: Use your textbook as a measuring tool to find how long each object is. Then compare your measured length with the actual length.

Exam Tip: Always measure carefully and record both estimated and actual lengths - examiners want to see that you tried to guess first and then checked your answer.

Question 2. Kavita is going to the school from her home. She is getting late. Which path should she use to reach the school fast? Mark it in the picture given below.
Answer: Kavita should take the shorter, more direct path shown by the yellow dashed line in the answer diagram. This path goes straight from her home to the school building without taking long detours around the trees and other obstacles.
In simple words: The fastest way is the path that takes fewer turns and goes straight toward the school.

Exam Tip: When finding the fastest route, always look for the path with the fewest turns and the least distance.

Question 3. Choose the longest path from A to B. Also make the shortest path between A and B.
Answer: The longest path winds through the grid following all the outer squares and making many turns before reaching B - this requires going around most of the grid. The shortest path moves directly from A to B taking only the minimum number of turns needed, going straight down and across in the most direct way possible.
In simple words: The longest path takes many turns and covers more ground. The shortest path goes the most direct way.

Exam Tip: Count the number of units traveled on each path - the longest has the most unit movements, while the shortest has the fewest.

Question 4. How Many Blocks? Let me stack the blocks and find the height of my toys.
Answer: By stacking colored blocks, you can measure the height of toys like a giraffe, camel, monkey, and elephant. Count how many blocks tall each toy is when you place it next to your block tower. The giraffe reaches 9 blocks high, the camel is 7 blocks tall, the monkey measures 2 blocks, and the elephant stands 5 blocks tall.
In simple words: Stack blocks next to each toy to measure how many blocks tall it is.

Exam Tip: Always stack blocks straight up without tilting - make sure each block sits flat on top of the one below it for an accurate count.

Question 5. Fill in the blanks.
A. The giraffe is _______ blocks tall.
B. The _______ is 7 blocks tall.
C. The monkey is _______ blocks tall.
D. The _______ is 5 blocks tall.
Answer:

B. The camel is 7 blocks tall.
C. The monkey is two blocks tall.
D. The elephant is 5 blocks tall.
In simple words: Match each animal with its correct height in blocks.

Exam Tip: Read the question carefully - check if you are filling in a number or an animal name before writing your answer.

Question 6. How long is your hand? Trace your hand in the space given below and count the number of lines.
Answer: You will trace around your hand on the lined paper and then count how many horizontal lines your hand outline covers. Since every child has a different hand size, the number of lines will vary. Once you count your lines, write that number as your answer. The example shown counts 13 lines for one student's hand.
In simple words: Draw your hand outline on the paper and count the lines it touches.

Exam Tip: Count carefully - include lines that your hand just barely touches, not just the ones completely inside the outline.

Project Work Question. Find the length of the following using any tool of your choice (eraser, blocks, pencil). Record your measurement.
- Any wall of your house
- Length of your bed
- Length of a door
Answer: When you use different tools like pencils, erasers, or blocks to measure:
Wall of house = 18 pencils = 90 erasers
Length of bed = 13 pencils = 70 erasers
Length of door = 15 pencils = 75 erasers
In simple words: Choose a tool like a pencil or eraser and measure each object by counting how many tools fit along its length.

Exam Tip: Record measurements in at least two different tools to show you understand that the same length gives different numbers depending on what you measure with.

Question 7. Look at the picture and compare which vegetables are lighter or heavier than the other vegetables.
Answer: Looking at the speech bubbles in the picture, the vegetables rank as follows from lightest to heaviest: Chilli is the lightest of all. Capsicum is lighter than cauliflower.

In simple words: Look at all the objects and circle the one that would be the heaviest to pick up.

Exam Tip: Think about which object would need the most effort to lift - that is your heaviest item.

Question 10. Circle the lightest one.
Answer: In group A: The pencil box (thin green item) is the lightest. In group B: The toy balloon is the lightest object in that group.
In simple words: Look at all the objects and circle the one that would be the easiest to pick up.

Exam Tip: Think about which object weighs the least or would be easiest to hold - that is your lightest item.

Question 11. Tick the vegetables and fruits which will make the balance go down. Mark Light (L) and Heavy (H).
Answer: Looking at each item:
A. Pumpkin is Heavy (H) - it will push the balance down.
B. Apple (red ball) is Light (L) - it will not push down as much.
C. Coconut is Light (L), Watermelon is Heavy (H), Lemon is Light (L).
D. Tomato is Heavy (H), Chilli is Light (L).
In simple words: Heavy fruits and vegetables will make the balance side go down. Light ones will make it go up.

Exam Tip: Remember - items marked H will tip the balance down, while items marked L will not be heavy enough to push it down.

Question 12. Look at the pictures and discuss the different types of balance used by people in the pictures given below. Tick the type of balance you have seen before.
Answer: There are four different types of balances shown in the pictures: a spring balance (used by shopkeepers with a hook), a beam balance with weights (used for cooking), a weighing scale (the kind used in shops to measure items like grains), and a traditional balance with two pans (used to compare weights of two objects side by side). All four types are commonly seen and used in everyday life, so you should tick all of them.
In simple words: Different balances work in different ways. Some have springs, some have two pans, and some use weights to find out how heavy things are.

Exam Tip: Be able to name at least two types of balances and explain where each one is used in real life.

Question 13. Fruits in the Park - Watermelon and mango want to play on the see-saw. Watermelon sits on one side, but he could not get up. His friend mango called other mangoes to sit on the other side.
A. How many mangoes will balance the watermelon? Find out from the picture given above.
Answer: 6 mangoes will balance the watermelon.
In simple words: The watermelon is much heavier than one mango, so you need many mangoes together to make the see-saw balance.

Exam Tip: Count the mangoes shown on the balance picture carefully - this teaches you that one heavy item can equal several lighter items.

Question 14B. How many coconuts can balance the watermelon if - Weight of 1 Coconut = Weight of 2 Mangoes?
Answer: 3 coconuts can balance the watermelon.
Since 1 coconut = 2 mangoes, and 6 mangoes balance the watermelon, then 6 mangoes ÷ 2 mangoes per coconut = 3 coconuts needed.
In simple words: One coconut is as heavy as two mangoes. Since six mangoes balance the watermelon, you only need three coconuts instead.

Exam Tip: When comparing different items, use the given relationship between them (like 1 coconut = 2 mangoes) to figure out how many of each item you need.

Project Work Question. Name some of your family members or friends who you think weigh almost the same as you, more than you, or less than you.

Your weight: 22 kg
In simple words: Compare your weight with family members. Your parents are usually heavier, your siblings might be similar, and younger children are usually lighter.

Exam Tip: You can check your weight at a doctor's clinic, hospital, or pharmacy - places that have medical weighing scales.

Question. Now Raghu wants to make nimbu pani for himself and his two friends. Raghu has to make 3 glasses of nimbu pani. Write the quantity of ingredients he has to use to make 3 glasses of nimbu pani.
Answer: When Raghu prepares nimbu pani for 3 people instead of 1, he must multiply each ingredient by 3. Water becomes 3 glasses (1 × 3). Sugar becomes 3 spoons (1 × 3). Lemon juice becomes 6 spoons (2 × 3). Salt becomes 3 pinches (1 × 3).
In simple words: To make the drink for 3 people instead of 1, take 3 times more of each thing - 3 glasses of water, 3 spoons of sugar, 6 spoons of lemon juice, and 3 pinches of salt.

Exam Tip: When you need to make more of a recipe, always multiply each ingredient by the same number. Check your answers by making sure each ingredient is multiplied by the same factor.

Question. Name some drinks that are prepared at your home. Find out the ingredients used for making your favourite drink and write them below.
Answer: One example is a lassi or buttermilk drink. To make lassi, you need 2 cups of yogurt (or curd), 1 teaspoon of sugar, a tiny pinch of salt, dry fruits like almonds or raisins as you like, and 2 cups of water. You blend all these ingredients together until smooth, then serve it cold. This is a popular homemade drink in many Indian homes and tastes refreshing on warm days.
In simple words: A lassi is made by mixing curd, sugar, salt, water, and dry fruits. Blend them all together and drink it chilled.

Exam Tip: Write the name of the drink clearly, then list each ingredient with how much you need. It is fine to give any homemade drink you know - milk-based drinks, fruit drinks, or herbal drinks are all good examples.

Question. Raghu's bottle is filled with four glasses of water.
A. How many glasses of water can fill your bottle?
B. How many glasses of water can fill your friend's bottle?
C. Does your friend's bottle fill with equal - more - less amount of water?
Answer:
A. Your bottle can hold 7 glasses of water.
B. Your friend's bottle can hold 8 glasses of water.
C. Your friend's bottle holds more amount of water than yours.
In simple words: Your bottle takes 7 glasses to fill. Your friend's bottle takes 8 glasses. So your friend's bottle is bigger and holds more water.

Exam Tip: Compare the numbers carefully - the bottle that needs more glasses of water to fill is the larger bottle. Always state which one is more and which one is less.

Question. Name the friend whose bottle can carry - Equal water as yours - Less water than yours - More water than yours
Answer:
A. Equal water as yours - Rahul
B. Less water than yours - Yogesh
C. More water than yours - Saikat
In simple words: Rahul's bottle is the same size as yours. Yogesh's bottle is smaller. Saikat's bottle is bigger and holds the most water.

Exam Tip: To match friends with bottle sizes, think about how many glasses fill each bottle. The friend with 7 glasses (like yours) matches equal; fewer glasses means less; more glasses means more.

Project Work

Question. To make a jal tarang (musical instrument), arrange 5-7 similar glasses or bowls. Fill them with varying levels of water. Gently tap a spoon on each glass or bowl and hear how each one sounds. Tap at different parts of the glass or bowl to feel the difference.
Answer: To make a jal tarang, gather 5 to 7 glasses or bowls that look alike. Pour different amounts of water into each one - start with one that is almost empty and keep adding more water to each glass so the last one is quite full. When you gently strike each glass with a spoon, you will hear different sounds - the glass with less water makes a higher sound, while the glass with more water makes a lower sound. By tapping different spots on the rim or side of the glass, you can also notice changes in the sound it creates. This simple musical tool shows how water level changes the pitch of sound.
In simple words: Fill glasses with different amounts of water. Tap each one with a spoon. Glasses with less water sound high, and glasses with more water sound low. This makes a simple musical instrument.

Exam Tip: Show your jal tarang and explain clearly that different water levels make different sounds. You may also tap different parts of the glass to show how it changes the sound made.

Question 1. Use your textbook to measure the length of the following objects.
Answer:

Exam Tip: Always fill in both the estimated and actual measurements - comparing them shows your understanding of how close your guess was to the real measurement.

Question 2. Kavita is going to the school from her home. She is getting late. Which path should she use to reach the school fast? Mark it in the picture given below.
Answer: Kavita should take the straight path marked with a yellow line. This is the fastest way because it goes directly from her home to the school without taking any extra detours around the buildings and obstacles.
In simple words: The straight line is always the quickest way to get from one place to another.

Exam Tip: When asked which path is fastest, always choose the one that goes most directly without unnecessary turns or longer routes.

Question 3. Choose the longest path from A to B. Also make the shortest path between A and B.
Answer: The longest path is shown by the red line that takes many turns and goes around the edges of the grid. The shortest path is shown by the red line that goes in a more direct way with fewer turns, reaching B as quickly as possible from A.
In simple words: A path that turns many times and goes around the edges is longer. A path with fewer turns and going more straight is shorter.

Exam Tip: Count the number of square edges each path covers - the longest path will cross more edges, while the shortest path crosses the fewest edges possible.

Question 4. How Many Blocks?
Answer:
Fill in the blanks:
A. The giraffe is 9 blocks tall.
B. The camel is 7 blocks tall.
C. The monkey is two blocks tall.
D. The elephant is 5 blocks tall.
In simple words: You can measure how tall each animal is by counting the colored blocks stacked on top of each other.

Exam Tip: Always count each block carefully from bottom to top - a block is a unit of measurement, just like a centimetre on a ruler.

Question 5. How long is your hand? Trace your hand in the space given below and count the number of lines.
Answer: Number of lines = 13
In simple words: When you trace your hand outline on lined paper and count how many lines it covers, that tells you how long your hand is using lines as the measuring unit.

Exam Tip: This is a practical activity - your actual number of lines will depend on how big your hand is and the spacing of the lines on your paper.

Question 6. Find the length of the following using any tool of your choice (eraser, blocks, pencil). Record your measurement.
Answer:
Wall of house = 18 pencils = 90 erasers
Length of bed = 13 pencils = 70 erasers
Length of door = 15 pencils = 75 erasers
In simple words: You can use different things like pencils or erasers to measure how long something is. You just line them up end to end and count how many you need.

Exam Tip: Different tools give different number values for the same length - a pencil is longer than an eraser, so the same object needs fewer pencils than erasers to measure.

Question 7. Look at the picture and compare which vegetables are lighter or heavier than the other vegetables.
Answer:
A. Muskmelon is heavier than carrot.
B. Capsicum is lighter than cauliflower.
C. Bottle gourd is heavier than carrot.
D. Carrot is lighter than bottle gourd.
E. Pumpkin is the heaviest of all.
F. Chilli is the lightest of all.
In simple words: When you put vegetables on a balance scale, heavier ones go down and lighter ones go up. You can order them from lightest to heaviest.

Exam Tip: Use a balance scale to compare weights - put one item on each side and see which side goes down to find the heavier object.

Question 8. Circle the heaviest one.
Answer: The backpack is the heaviest object among the three items shown (pen, textbook, and backpack).
In simple words: The backpack weighs more than a pen or a book, so it is the heaviest.

Exam Tip: When comparing weights of objects, think about what each thing is made of and its size - larger or solid objects are usually heavier.

Question 9. Circle the lightest one.
Answer: The toy spinning top is the lightest object among the three items shown (cake decoration, book, and spinning top).
In simple words: The spinning top weighs much less than a decorated cake or a book, so it is the lightest.

Exam Tip: Small objects made of plastic or hollow materials are usually lighter than solid or filled objects of greater size.

Question 10. Tick the vegetables and fruits which will make the balance go down. Mark Light (L) and Heavy (H).
Answer:
A. Pumpkin (H)
B. Tomato (L)
C. Coconut (H)
D. Apple (L), Lemon (L)
E. Watermelon (H)
F. Carrot (L), Chilli (L)

Vegetables and fruits marked with (H) are heavy and will make the balance go down. Those marked with (L) are light and will make it go up.
In simple words: Heavy things like pumpkins and watermelons pull the balance down. Light things like carrots and lemons make it go up.

Exam Tip: A balance scale tilts down on the side with the heavier object - use this to sort vegetables into heavy and light groups.

Question 11. Look at the pictures and discuss the different types of balance used by people in the pictures given below. Tick the type of balance you have seen before.
Answer: The pictures show four different types of balances used in daily life:
1. A traditional beam balance with a pan (used at home)
2. A kitchen scale (used for cooking)
3. An electronic weighing scale (used in shops)
4. A traditional pan balance (used by vendors)

All four types of balances are commonly seen and used to measure the weight of different things.
In simple words: Different types of balances help us measure how heavy things are. Some use a beam, some are electronic, and some use pans.

Exam Tip: Be familiar with different types of weighing scales found in everyday life - beam balances, kitchen scales, digital scales, and traditional two-pan balances.

Question 12. Fruits in the Park - How many mangoes will balance the watermelon? Find out from the picture given above.
Answer: 6 mangoes will balance the watermelon.
In simple words: When you look at the balance scale in the picture, you can count that six mangoes together weigh the same as one watermelon.

Exam Tip: On a balanced scale, objects on both sides weigh the same - count the items on one side and compare with the other side.

Question 13. How many coconuts can balance the watermelon if - Weight of 1 Coconut = Weight of 2 Mangoes
Answer: 3 coconuts can balance the watermelon.

In simple words: Since 1 coconut weighs the same as 2 mangoes, and 6 mangoes balance the watermelon, we need only 3 coconuts to balance it.

Exam Tip: Use the relationship given to convert one measurement to another - if 1 coconut = 2 mangoes, and you know how many mangoes balance the watermelon, you can find how many coconuts are needed.

Question 14. Name some of your family members or friends who you think weigh - A. almost the same as you, B. more than you, C. less than you. Find out the places where you can check your weight. What is your weight?
Answer:
A. Almost the same as you - Big Brother
B. More than you - Father
C. Less than you - Younger Sister

Places where you can check your weight: Health centres, doctor's clinics, gymnasiums, schools (during health checkups).

Your weight: 22 kg
In simple words: You can compare your weight with people you know, and you can find your actual weight at hospitals, clinics, or gyms using a weighing scale.

Exam Tip: Personal weight answers will vary - be honest about your own weight and realistic when comparing with family members based on their relative sizes.

Question. Now Raghu wants to make nimbu pani for himself and his two friends. Raghu has to make 3 glasses of nimbu pani. Write the quantity of ingredients he has to use to make 3 glasses of nimbu pani.
Answer: When Raghu makes nimbu pani for 3 glasses instead of 1 glass, he needs to multiply each ingredient by 3. So he will need 3 glasses of water, 3 spoons of sugar, 6 spoons of lemon juice, and 3 pinches of salt.
In simple words: To make 3 glasses, take all the amounts from 1 glass and multiply each one by 3.

Exam Tip: Always multiply each ingredient in the same way when making more of a recipe - this shows understanding of scaling quantities.

Question. Name some drinks that are prepared at your home. Find out the ingredients used for making your favourite drink and write them below.
Answer: One favourite drink prepared at home is buttermilk. The ingredients needed to make this drink are curd (2 cups), sugar (1 teaspoon), salt (1 pinch), dry fruits as per your taste, and water (2 cups). You can mix all these ingredients together and serve it chilled.
In simple words: Choose any drink you like that is made at home, then list what goes into it and how much of each thing you need.

Exam Tip: Write the name of the drink clearly and give the exact amount of each ingredient - this shows you understand how drinks are made at home.

C. Does your friend's bottle fill with equal/more/less amount of water?
Answer:
A. How many glasses of water can fill your bottle? 7 glasses
B. How many glasses of water can fill your friend's bottle? 8 glasses
C. Does your friend's bottle fill with equal/more/less amount of water? More amount of water
In simple words: Your bottle holds 7 glasses of water, your friend's bottle holds 8 glasses. Your friend's bottle can hold more water than yours.

Exam Tip: Compare the numbers carefully - the bottle that needs more glasses of water can hold a larger amount.

Question. Name the friend whose bottle can carry - equal water as yours, less water than yours, or more water than yours.
Answer:
A. Equal water as yours - Rahul
B. Less water than yours - Yogesh
C. More water than yours - Saikat
In simple words: Different friends have bottles of different sizes - some match yours, some are smaller, and some are bigger.

Exam Tip: Match each friend's name to the right size comparison - this tests your understanding of equal, less, and more.

Question. To make a jal tarang (musical instrument), arrange 5-7 similar glasses or bowls. Fill them with varying levels of water. Gently tap a spoon on each glass or bowl and hear how each one sounds. Tap at different parts of the glass or bowl to feel the difference.
Answer: Set up 6 glasses or bowls in a row. Put different amounts of water in each one - the first glass should be empty, and each glass after that should have more water than the one before it. When you tap each glass with a spoon, you will notice that the glass with less water makes a higher sound, while the glass with more water makes a lower sound. This happens because the amount of water changes how the glass vibrates. By tapping different parts of the glass, you can also hear slight changes in the sound quality.
In simple words: Different amounts of water in glasses make different sounds when you tap them - more water means a deeper sound, less water means a higher sound.

Exam Tip: Explain the link between water amount and sound pitch - this shows you understand how vibrations change with different quantities.
