LO: I can use column addition with one exchange.


Today we are going to move onto column addition where the exchange is in the ones or tens column. This is to help us remember how we do the exchange with a gradual build up.

Again, use practical or visual resources alongside to help you to begin with to remind you of the process.

Remember, when you need to exchange you are not adding or taking away anything to the number you are exchanging between the ones, tens and hundreds. The actual number stays the same. Remember to use the word exchange.

Top tips for column addition

  • Put the HTOs at the top.
