ECG 14 – TAKE AWAY FROM A GROUP

Children begin to informally investigate taking away from a group.
They explain that they are starting with 1 group, and taking a group away.
Children use their number sense to identify which number they could make a group of, that would give them enough to take away the other number.

We’ve swapped the order that we introduce adding and taking away!
Our work in schools has shown us that children develop understanding of taking away better if it is introduced before adding. Before children start selecting 2 numbers and making 2 groups, the develop understanding of selecting 2 numbers and thinking about ‘which number they could make a group of that would give them enough to take away a group of the other number’.
