The new addition sums.

These are incredibly easy, but they need some time to get used to.

We'll be doing these sums all week...so don't worry if your child has come home a bit confused. I have done these in class extensively, I gave a note in the study copybook and have printed a note too.

Here is the note I gave you :

Basically, we have a 'teen number' to which we are adding a single digit number.

We have to find the pair of 20 of the teen number (the 'friend'). In this case, the friend of 16 is 4.

We need to add 9 to 16 not just 4. So we count on (Ponn) from 4 to 9. The answer to this is 5. In fact, 4 + 5 = 9

So now we have a group of 20 + 5.

Answer is 25.
