CBSE Class 4 Maths Patterns And Designs Worksheet Set 02

Competency : Understanding Basic Concepts

 

Question 1. Complete the given patterns.

Answer:
(a) The first pattern shows a leaf-like loop growing petals sequentially (1, 2, 3, 4 petals). Completing the sequence in the empty boxes:
- Box 5: A figure with 5 petals.
- Box 6: A figure with 6 petals.
- Box 7: A figure with 7 petals.
- Box 8: A figure with 8 petals.

(b) The second pattern alternates two vertical arrows (each box has an up arrow and a down arrow side by side). Repeat the same pair in every empty box:
- Box 3: Arrow pointing up on left, arrow pointing down on right.
- Box 4: Arrow pointing up on left, arrow pointing down on right.
- Box 5: Arrow pointing up on left, arrow pointing down on right.
- Box 6: Arrow pointing up on left, arrow pointing down on right.
- Box 7: Arrow pointing up on left, arrow pointing down on right.
- Box 8: Arrow pointing up on left, arrow pointing down on right.

(c) The third pattern shows a triangle rotating 90 degrees or 180 degrees counter-clockwise or alternating orientations (pointing up, pointing vertically symmetric/split, pointing left, pointing down, etc.). Continuing the cyclic rotation:
- Box 4: Triangle pointing right.
- Box 5: Triangle pointing up.
- Box 6: Triangle pointing vertically split / symmetric.
- Box 7: Triangle pointing left.
- Box 8: Triangle pointing right.
In simple words: Observe how each shape changes, rotates, or increases step-by-step, and repeat that exact rule to fill the remaining boxes.

Exam Tip: Always look for rotation angles (90 degrees, 180 degrees) or repeating units in visual pattern worksheets.

 

Question II. Make a pattern using in the boxes given below.
Answer:
A repeating pattern can be formed by turning the given symbol by 90 degrees clockwise in each successive box:
- Box 1: Symbol in its original position.
- Box 2: Symbol turned 90 degrees clockwise.
- Box 3: Symbol turned 180 degrees.
- Box 4: Symbol turned 270 degrees.
- Boxes 5 to 8: Repeat the same four positions.
In simple words: Turn the shape a quarter turn (90 degrees) each time to create a neat turning pattern.

Exam Tip: Clear and neat drawings with consistent rotations fetch full marks in design questions.

 

Continue the shading pattern in the grid below.

Answer:
The grid pattern shows alternating shaded squares and patterned/cross-hatched squares in a checkerboard or diagonal sequence. To complete the grid:
- Extend the diagonal alternating shading of dark solid squares and textured/dotted squares row by row.
- Ensure that no two identical shading types share a direct edge unless required by the specific checkerboard symmetry of the given sample block.
In simple words: Follow the alternating dark and textured pattern diagonally across the grid squares.

Exam Tip: Use a pencil to lightly shade first to avoid mistakes before finalizing with darker shading.
