Last time I focused on some basics about learning the number bonds (combinations) of 10 as well as adding 10 to any number. Today I want to show the benefits of **making a 10** when adding numbers with sums greater than 10 (such as 8 + 5). Then I’ll show how to help students **add up** to apply that to addition and subtraction of larger numbers. I’ll model this using concrete and pictorial representations (which are both important before starting abstract forms).

__Using a 10 Frame:__

A ten frame is an excellent manipulative for students to experience ways to “Make a 10.” I am attaching a couple of videos I like to illustrate the point.

- Video 1: Make a Ten video
- Video 2: Make a Ten strategy
- Ten frame template (FREE): Making 10 activity board by Louise Leger

Let’s say the task is to add 8 + 5:

- Model this process with your students using 2 ten frames.
- Put 8 counters on one ten frame. (I love using 2-color counters.)
- Put 5 counters (in another color) on the second ten frame.
- Determine how many counters to move from one ten frame to the other to “make a 10.” In this example, I moved 2 to join the 8 to make a 10. That left 3 on the second ten frame. 10 + 3 = 13 (and 8 + 5 = 13).

The example below shows the same problem, but this time move 5 from the first ten frame to the second ten frame to “make a 10.” That left 3 on the first ten frame. 3 + 10 = 13 (and 8 + 5 = 13). Continue reading
