Lesson details

Key learning points

  1. Base ten blocks and 100s frames can represent multiples of ten.
  2. The symbol × means multiply or lots of.
  3. Any 3-digit multiples of ten can be written as a multiplication equation.

Common misconception

Pupils may explain the relationship with multiples of 10 as 'adding a zero' (e.g. 37 x 10 = 370).

Pupils should be discouraged from doing this. Instead, explore place value, reminding pupils that each 100 represents 10 lots of ten.

Keywords

  • Equation - An equation is used to show that one number or calculation is equal to another.

  • Multiple - A multiple is the result of multiplying a number by another whole number.

Pupils may need to represent multiples of ten using base ten blocks or 10s counters and 'hundreds' frames.
