Twelve subtraction problems stacked one number above the other, each in its own rounded card with an answer box underneath. A small robot waves from the corner.
This is the way subtraction will be written for most of school, so it is worth meeting it early with small numbers. There are no pictures to count, which makes it the right page for a child who has been doing the picture sheets and is ready for a step up.
5 − 0 and 4 − 4 are mixed in with the rest, and 9 − 8 and 10 − 1 show that a big number minus a big number can still leave something small.
