A strategy to teach elementary students for increased math fact fluency.
Problem: My students spent so much time counting on to add. It’s not efficient!
Solution: While there are a variety of strategies for adding, one of my most recent discoveries is what I call the “in betweens” strategy. Here’s how it works:
When you see two addends that only have one number in between them….
You take the in between number and double it.
Here is why it works:
When you move a cube from the bigger number to the smaller number, you get a simple doubles fact!
Easy, right?!? Where was that one when I was a kid?
Want to encourage your students to use efficient strategies for adding and subtracting? Check out my addition and subtraction strategies posters (9 posters, including the “in betweens” strategy) over at Teachers Pay Teachers:

i love how you have a poster to explain why the in between strategy works.
