Learning objects The multiplier: generate easy multiplications


Solve multiplications such as 9x88. Use a partitioning tool to help solve randomly generated multiplications. Learn strategies to do complex arithmetic in your head. Split a multiplication into parts that are easy to work with, use simple times tables, then solve the original calculation. This learning object is one in a series of five objects.

Educational details

Key learning objectives
  • Students apply the distributive property to calculate products mentally involving one two-digit number and one single digit number.
  • Students use known multiplication facts to calculate products in their head.
  • Students partition numbers to find products that are easy to calculate mentally.
  • Students investigate and apply strategies that make calculating products easier.
Educational value
  • Helps students develop mental strategies to simplify and solve multiplication problems.
