Getting better at addition

By this point single-digit facts should be automatic and the work moves to the written column method with carrying. Errors here are usually procedural rather than arithmetic: the carried digit is written small, above the next column, and it is the thing most often forgotten once attention moves on. Saying the carry aloud as it is written fixes most of them.

Frequently Asked Questions

How can I help my child get faster at addition?

Target the strategies rather than the sums. Make-a-ten and near-doubles cover most of the facts children find hard, and both depend on knowing number bonds to 10 instantly. Short daily practice beats long sessions — recall is built by frequency.
