NCERT Solutions for Class 1 Maths Chapter 02 What is Long, What is Round

Question A. Draw round objects in ○ and long objects in [ ].
Answer:
* Round Objects (to draw in the circle): A colorful beach ball, a plate with roti, a cup cake or bun, a watermelon, and a fresh orange.
* Long Objects (to draw in the rectangle): A water bottle, a pencil box, alphabet blocks, a toy robot, and building blocks.
In simple words: We put round things like balls and fruits in the circle. We put long things like bottles and boxes in the rectangle.

Exam Tip: Round objects look like balls, while long objects look like pencils or bottles.

Question B. Match the objects which are similar in shape.

Answer: The correct matching pairs of objects with identical shapes are shown in the table above.
In simple words: We match things that have the same shape, like a soccer ball with a toy ball or a box with a book.

Exam Tip: Look at the edges and corners of each object to easily match similar shapes.

Question C. Tick the shape which is similar to ball.
Answer: The object similar to a ball is the watermelon (first option).
In simple words: A watermelon is round just like a ball, so we tick it.

Exam Tip: A ball is round and can roll, just like a watermelon.

Question D. Tick the shape which is similar to cap.
Answer: The shape similar to a birthday cap is the paper cone (first option).
In simple words: Both the birthday hat and the paper cone have a pointed top.

Exam Tip: Objects with a pointed top and flat round base are cone-shaped.

Question E. Tick the shape which is similar to glass.
Answer: The shape similar to a glass is the water bottle (second option).
In simple words: Both the glass and the water bottle are long and round (cylindrical).

Exam Tip: Cylinder-shaped objects can stand upright and have a curved long side.

Question F. Tick the shape which is similar to glass.
Answer: The shape similar to a pencil box is the matchbox (third option).
In simple words: Both the pencil box and the matchbox have flat rectangular sides and corners.

Exam Tip: Box-shaped objects have flat faces and straight corners.

Question. Make a house, toy, tower, robot, bus or anything you like using different objects in your surroundings. You can also use notebooks, books, pencil box, water bottle, waste or old boxes, birthday caps, funnels, etc.
Answer: This is a fun craft activity. You can build interesting toys using things around you:
* Use a notebook or pencil box for the main body of a robot or house.
* Use birthday caps or funnels for the head or arms.
* Use old bottle caps or small plastic cups for feet or wheels.
In simple words: Collect some cardboard boxes, books, and bottle caps at home to build your own toy robot or tower.

Exam Tip: Combining different shapes (like flat boxes for walls and round caps for wheels) helps you build strong structures.

Question A. Write ‘R’ for rolling objects and ‘S’ for sliding objects in the ○ given in the below picture.
Answer: Here are the correct actions for each object shown in the park:
* Sliding (S): Kids sliding down the slide, the cardboard box on the grass.
* Rolling (R): The round ball on the grass, the wooden logs, the round can on the stand.
In simple words: Things with flat sides slide down (like boxes), while round things roll easily (like balls and logs).

Exam Tip: Round objects roll because they have curved surfaces, while flat objects slide because they have flat faces.

Question B. Collect different objects from your surroundings and see if they roll or slide.
Answer: Here is what happens when you play with different items:
* Roll: Basketball, tennis ball, marbles, orange.
* Slide: Notebooks, plates, lunchbox, wooden blocks.
In simple words: Round things like marbles and balls roll on the floor. Flat things like books and blocks slide when we push them.

Exam Tip: Test items at home by placing them on a sloping surface to see if they roll or slide.

Question C. Do you see things which can do both, roll and slide? If yes, discuss in the class.
Answer: Yes, there are many objects that can both roll and slide depending on how you place them:
* Coin: Slides when kept flat, rolls when stood up on its edge.
* Pencil: Slides when pushed on its flat tip, rolls when laid on its long side.
* Water Bottle: Slides on its flat bottom, rolls when laid down on its curved side.
In simple words: Some items can do both! A coin rolls on its edge but slides when it lies flat on the table.

Exam Tip: Objects with both flat and curved surfaces (like a cylinder or a coin) can both roll and slide.

Question. Find whether the following objects roll, slide or do both. Put [tick mark] or [cross mark]

Answer: The finished table above classifies each object by whether it rolls (✔), slides (✔), or does both (✔).
In simple words: Round things roll, flat things slide, and things with both flat and round parts (like cups or bottles) can do both!

Exam Tip: If an object has flat bases and curved sides (cylinders/cones), it will always fit in the "Rolls as well as slides" category.
