Shape patterns

Mathematics · Multiplication & Division · procedural

Generate a number or shape pattern that follows a given rule; identify apparent features of the pattern not explicit in the rule and explain informally why they occur

What mastery looks like

  • Given 'start at 1, add 3', generate terms and notice they alternate odd/even
  • Given a shape pattern, predict the next three terms and describe the rule
  • Explain why starting at 2 and adding 4 always gives even numbers

Check your understanding

If Shape patterns is told 'start at 3 and multiply by 2 each time', can they write out the pattern — 3, 6, 12, 24, 48 — and spot any interesting features in how it grows?
