Distributive property

Google Classroom

🎯 Objective: Students break apart a factor to multiply (7 × 8 = 7 × 5 + 7 × 3).

Lesson outline

  1. Show an 8 × 7 array and ask: who knows 8 × 7 by heart? Who knows 8 × 5 and 8 × 2?
  2. Draw a line to split it into 8 × 5 and 8 × 2; record 8 × 7 = (8 × 5) + (8 × 2) = 40 + 16 = 56.
  3. Students split 6 × 9, 7 × 6 and 4 × 8 on grid paper, choosing a split with a fact they know (often 5s or 2s).
  4. Exit: solve 6 × 9 by breaking apart and write the equation.
