How to add numbers together

To add numbers together you can use a variety of written methods such as the column method, or a number line; or you could use a mental arithmetic method.

Resources for physically adding numbers together could include: an abacus, a 100 square, Cuisinaire rods, Numicon, Base 10 or simply use cubes or counters.

 Try using more than one method and practice checking your answers with a calculator.
