Before, I always felt that some kids just naturally make a ten in their mind, and some will come to it later. I exposed the kids to the strategy, but it was just that, a strategy. However, after really looking at Engage New York (Eureka) and the Common Core Standards and Mathematical Practices I focused my instruction on the concept of making a ten.
I taught it as a story, telling the kids that all numbers want to be a 10 or a multiple of 10. They need a BFF to do so, and we started learning our facts to 10 as pairs of best friends. Then the numbers made a happy ten. This made them laugh and made them learn it.
As the numbers grew larger and we discovered place value with tens and ones, I was even more sold on the strategy. The kids were adding and subtracting numbers with ease using the simple make a ten strategy. They transferred it right on to multiples of ten. It was awesome to see.
Even though it was hard for some to grasp at first, I stuck with it and now I can confidently say that all my kids can make a ten!
If you are interested in any units, I have a few below. I teach math using Power Points. They keep me moving forward even though we move from desks, to carpet, to games, etc. They are organized around the Common Core Standards and the Mathematical Practices.
