A good way for learners to understand the importance of using reverse calculations to check an answer to a previous question. These check questions are appearing more and more in functional skills exams. I hope you find it as useful as I and my learners do.

I've just designed this ready for my new starts in September. It is surprising how many learners come that get basic things wrong.

As we know FS is all about reading the questions and showing workings out. I always do 5 weeks of no calculators as for some they just do not get the borrowing / carrying over and this is of course important on the non calculator papers now.

There is also an E2-E3 version of this resource.

This is a MS Excel resource that is designed to be a useful resource for producing sheets for starter activities or homework. This also provides a tutor marking sheet. The sheet can be used to differentiate by choosing larger or smaller numbers, and can be addition or subtraction.

Creates printable sheets of 20 problems (plus answer sheets). Clever and useful!
