This EYFS Recall One Less Learning Activity enables children to develop their understanding of the one less than relationship between consecutive numbers to 20. Children identify the number at the beginning of the function machine and then recall what is one less. Children can write the numeral in the box to show their answer or use number cards instead. This activity can be completed practically, using equipment if necessary, but children should be encouraged to recall the one less than facts wherever possible.

It covers the following objectives for children in reception:

(M-23) Link the number symbol (numeral) with its cardinal number value.

(M-26) Understand the one more than/one less than relationship between consecutive numbers.
