Guest Post and Video - Adding Larger Numbers By Making Ten

This is a good method of adding larger numbers together but it does take a little bit of practice for the kids.

Before you start explaining this, make sure your kids are confident with number bonds to 10 and with adding single digit numbers to 10 (eg 10 + 6 = 16).

We started by using this Make 10 poster and I explained that you need to take 2 from the 5 and add it to the 8 to get 10 and then you add the remaining 3 to the 10 which is 10 +3 = 13.

My son understood the logic but we still practiced it first with counters. I always thinks it make sense for the kids if they can use physical items to illustrate the maths concept. We used the Add by Making 10 Worksheets here.

Once he had tried a few with the counters he quickly went on to doing it automatically.

It may take a bit of practice to begin with but, if the kids can understand and master this addition strategy, it does make harder addition sums a lot easier - so it is worth practising.

There is more on Addition Within 20 here.
