Lesson plan

Goal

  • Students can do this: arithmetic patterns in addition and multiplication tables.

Teach (10 min)

  • Even × anything is even. Odd × odd is odd.
  • Multiples of 5 end in 0 or 5.
  • Work one example on the board while students say each step aloud, then do one together.

Practise (15 min)

  • Students work the printable sheet in pairs, then alone.
  • Or practise it as a game with no sign-up: https://peabody.kids/math/numsense.g3_patterns?lesson=3-numsense-patterns-1&at=3

Exit ticket (5 min)

  • Three questions on a slip:
  • 1. Without working it out all the way, will 11 × 9 be even or odd?
  • 2. Which number is in the 5s table (a multiple of 5)? Look at the ones digit.
  • 3. Which number is in the 5s table (a multiple of 5)? Look at the ones digit.
