Number Talks – Adding Up In Chunks

Here we are with our second NumberTalks strategy video, this time demonstrated by our fabulous Eilidh.

Go to this Sway

NumberTalks is all about finding a strategy that works for you. We know in Primary 4 that not everyone will prefer to use the same strategy and that’s why trying out lots of different methods is so important!

Here are some addition calculations for you to try at home. You can try out the ‘Adding Up In Chunks’ strategy to complete the calculation. Some of the children might prefer double check their answers using the partitioning strategyΒ  shown last week (it is proving to be a preferred strategy with lots of primary 4) & that is ok!

Have fun!
