Grade 2 · Unit 4: Patterns and algebra

Describing patterns

Say the rule, then predict.

Patterns in art

Rickshaw art has bright repeating patterns. Maths patterns can repeat or grow. To describe a pattern, find its rule.

A growing pattern

This is a growing pattern. Each term is 3 more than the last. So the next term is 16.

Shape patterns that grow

Step 1 has 1 triangle, step 2 has 2. Step 10 will have 10 triangles. Finding the rule helps you predict far ahead.

Patterns on a hundred square

Colour the numbers you say when counting in 5s. They make two straight lines. Every number ends in 5 or 0.

The core of a pattern

The part that repeats is the core: triangle, triangle, square. The same pattern can be shown with letters, sounds or beads: A, A, B. Shrinking patterns go down: 18, 15, 12, 9, 6 – take away 3 each time.

What I learnt

• I can describe the rule of a pattern.
• I can continue and predict patterns.
