Lesson Details

Key learning points

When counting in fives, each number ends in either 0 or 5
Each time there is an even number of fives, they fit together to makes a ten.
The pattern when counting can be used to help us remember the numbers.

Common misconception

When counting in fives, children may revert to the pattern of counting in tens after reciting a decade number.

Use practical equipment such as ten frames and base ten number boards to highlight why the next number in our count could not be a decade number. Explore the pattern in the digits and display these in the environment to promote further discussion.

Keywords

Fives - We can skip count in 'fives', or the multiples of five.
