Shape Patterns

NCERT anchor: NCERT Joyful Mathematics Class 1 — Chapter 2: What is Long? What is Round? (shape sequences)

• Extend patterns of circle, square, triangle shapes.
• Find the repeating unit of shapes in a row.
• Draw the next shape in rangoli-style repeating designs.

1. Shape repeats like colour

Level 1 (Verbal): circle, square, circle, square…

Level 2 (Symbolic): ○ □ ○ □ → next is ○.

Visual: Trace shapes in order left to right.

2. Core unit with shapes

[Circle, square] repeats — two shapes in the unit.

3. Three-shape units

Triangle, circle, square, triangle, circle, square… — unit length 3.

Rangoli border with shape pattern

Step 1 — Border shows: △ ○ □ △ ○ □ △ ?
Step 2 — Unit = triangle, circle, square (3 shapes).
Step 3 — After △ comes ○ in the unit → but last shown is △, so next is **○**.
Step 4 — Wait: sequence ends △ — position after △ in unit is ○.
Answer: next shape = circle (○).

• Next in ○ □ ○ □ ○ ?
• Core unit of △ △ ○ △ △ ○ ?
• Draw three repeats of □ ○.
• Stretch: If unit has 4 shapes, how many shapes in two full repeats?

Revision tip: Cover the last shape — predict it from the unit, then uncover to check.
