Extend the patterns by drawing further.

Question 1. Extend the patterns by drawing further (A to H).
Answer:
* A. Sticks and Stones: The pattern alternates as: 1 Stick, 1 Stone, 1 Stick, 1 Stone, 1 Stick, 1 Stone, 1 Stick, 1 Stone, 1 Stick.
* B. Garland: The garland continues with alternating hanging green leaves and little blue flowers.
* C. Lights: The pattern alternates as: 1 clay diya, 1 candle, 1 clay diya, 1 candle, 1 clay diya, 1 candle, 1 clay diya, 1 candle.
* D. Star Hanging: The hanging string continues with repeating star-shaped buntings and vertical rows of beads.
* E. Bunting Banners: The hanging banners alternate as: 1 triangular banner, 1 rectangular banner, 1 triangular banner, 1 rectangular banner.
* F. Border Design: The colorful blue border continues with its repeating geometric chevron zigzag lines and yellow dots.
* G. Sweets Plate: The pattern around the plate alternates with 1 round sweet and 1 square sweet.
* H. Salad Plate: The pattern around the plate alternates with 1 red strawberry and 1 green sliced cucumber.
In simple words: We look at the shapes and colors that repeat, then we draw them in the same order to make the patterns longer.

Exam Tip: Find the repeating "unit" first (like 1 diya and 1 candle) so you know exactly what to draw next.

Question 2. Munna is very fond of colouring. He created a pattern by using the impression of his thumb and fingers. You can also create a pattern like this by using your finger print in the given space. What colour should come after pink and why? Discuss.
Answer:
The color that should come after pink is grey.
* Reason: The fingerprint pattern at the bottom alternates between pink and grey. Since the last fingerprint is pink, the next one must be grey to keep the alternate pattern going.
* Rcreative Drawings: Students can use their colorful finger impressions to draw cute animals like frogs, turtles, horses, cats, and birds as shown in the picture.
In simple words: The dots go pink, grey, pink, grey. After a pink dot, we must use a grey dot. We can also make cute animals using our messy fingerprints!

Exam Tip: Alternate patterns always switch back and forth between two choices, like pink and grey.

Question 3. Extend the patterns by drawing further (Shapes).
Answer:
* Row 1 (Circles): The pattern alternates colors: Red circle, Blue circle, Red circle, Blue circle, Red circle, Blue circle, Red circle, Blue circle, Red circle.
* Row 2 (Shapes): The pattern alternates shapes: Yellow triangle, Green square, Yellow triangle, Green square, Yellow triangle, Green square, Yellow triangle, Green square.
* Row 3 (Arrows): The pattern repeats directions: Up arrow, Right arrow, Down arrow, Up arrow, Right arrow, Down arrow, Up arrow, Right arrow, Down arrow.
* Row 4 (Hexagons & Stars): The pattern repeats as: 1 Blue hexagon, 2 Red stars, 1 Blue hexagon, 2 Red stars, 1 Blue hexagon, 2 Red stars, 1 Blue hexagon.
In simple words: We follow the repeating shapes, colors, or directions to complete each row.

Exam Tip: Say the names of the shapes out loud (like "Up, Right, Down") to hear the pattern rhythm and find the next shape easily.

Question 4. Complete the pattern.
Answer:
The patterns grow or shrink step-by-step:
* Row 1 (Triangles): The triangles increase by 1 each time: 1 triangle, 2 triangles, 3 triangles, 4 triangles, 5 triangles.
* Row 2 (Lines): The shapes add 1 line each step to build a box: 1 line (stick), 2 lines (corner), 3 lines (open box), 4 lines (square), 5 lines (square with tail), 6 lines (divided square), 7 lines (window pane).
* Row 3 (Diamonds): The green triangles inside decrease: 4 triangles, 3 triangles, 3 triangles, 2 triangles, 2 triangles, 1 triangle.
* Row 4 (Pyramids): The orange pyramids decrease by 1 each time: 5 pyramids, 4 pyramids, 3 pyramids, 2 pyramids, 1 pyramid.
In simple words: Some patterns grow bigger by adding one, and some get smaller by taking away one.

Exam Tip: Count the elements in each box first. If the count goes 1, 2, 3... then the next boxes must have 4 and 5.

Question 5. Complete the number patterns (Milestones, Caterpillars, Trains, Necklaces, Pond, Flowers).
Answer:
The completed number patterns are:
* Triangular Buntings (Skip-counting by 2): 1, 3, 5, 7, 9, 11, 13
* Caterpillar (Counting backwards): 22, 21, 20, 19, 18, 17, 16
* Train Carriages (Skip-counting by 10): 10, 20, 30, 40, 50, 60
* Beads Necklace (Skip-counting by 11): 11, 22, 33, 44, 55, 66, 77
* Lily Pads in Pond (Skip-counting by 5): 5, 10, 15, 20, 25, 30
* Yellow Flowers (Skip-counting by 3): 2, 5, 8, 11, 14, 17, 20
In simple words: We find the missing numbers by skip-counting forward (like by 2s, 5s, or 10s) or counting backward by ones.

Exam Tip: Find the difference between the first two numbers (for example, 5 and 10 have a difference of 5) to know how much to skip-count by.

Question 6. Murthy and Vani are helping their Amma in making kolam or rangoli. You can also help them by completing the below kolam.
Answer:
To complete the symmetric kolam design, draw matching loops around the dots on the right side of the paper to mirror the left side.
In simple words: We copy the loops from the left side onto the right side to make a beautiful, balanced flower design.

Exam Tip: A kolam is symmetric. This means both the left and right halves must look exactly the same.

Question 7. Project Work
A. Collect pebbles, flowers, leaves, glasses, bowls, sticks, bangles, coins, caps, etc., and arrange them in a pattern. Create different patterns of jewellery, floral pot arrangements, art showpieces, etc.
B. Observe and find the patterns in nature like leaves, butterfly, animal skins (cat, dog, zebra, tiger), curtains, sarees, dupattas, tiles, beehive, etc.
C. Collect different objects seen around and make a collage.
D. Create patterns using different actions like clapping, snapping your fingers, stamping your feet, etc.
Answer:
These are fun hands-on projects:
* A, B & C: Collect fallen leaves, flowers, and stones from outside to paste and create beautiful patterned collages or designs.
* D: You can create a musical pattern using body sounds like: Clapping, Stamping, Clapping, Stamping.
In simple words: We can find patterns everywhere - on butterfly wings, on our clothes, and even in the sounds we make when we clap!

Exam Tip: Look closely at floor tiles or brick walls at home to find interesting repeating geometric patterns.
