Lesson details

Key learning points

  1. For any multiple of 10 the place value of the ones column is zero.
  2. For any multiple of 5 the place value of the ones column is zero or five.
  3. Any multiple of 10 is also a multiple of 5 and 2.

Keywords

  • Divisibility - Divisibility is a number’s ability to be exactly divided by another number, leaving no remainder.

Common misconception

A number is a prime if it is not divisible by 2, 3, 5 or 10.

A factor of a number can be greater than 10.

Give students the opportunity to create their own 'reveal a number' grid. This will give students the opportunity to consider examples and non-examples to ensure that the correct number is revealed.
