Concepts

Once children are confident with adding and subtracting numbers up to ten the next stage is to introduce addition of ten to a number. Before doing this children should be confident with counting in the teens.

Subtraction develops by taking ten from a teens number.

Once again lots of oral work needs to be done with these and children will probably need the aid of a number line to begin with.
