Multiply & Add Problems

Mathematics · Multiplication & Division · procedural

Solve problems involving multiplying and adding, including using the distributive law, integer scaling problems, and harder correspondence problems

What mastery looks like

  • Use the distributive law to solve 14 × 6 as 10 × 6 + 4 × 6
  • Solve a scaling problem (e.g. 'A tower is 3 times as tall as a 15 m building')
  • Solve a correspondence problem (e.g. '3 types of bread, 4 types of filling — how many different sandwiches?')

Check your understanding

If Multiply & Add Problems needs to work out '5 × 23', can they split it into '5 × 20 + 5 × 3 = 100 + 15 = 115' — rather than just jumping straight to a written method?
