This week, Year 4 have been perfecting column addition. We started the week by adding two three digits numbers, before ending the week with adding four digit number with more than one exchange!
It’s important to remember to set out your columns correctly.
Which are correct? Spot and explain the mistakes in the others.
When exchanging, we know that we can…
Exchange ten 1s for one 10…
Exchange ten 10s for one 100…
Exchange ten 100s, for one 1000…
Help at home: Practice chanting the exchange rules. I say it, you say it, we say it! You can even say them in silly voices!
