Studying Math Facts-Patterns with 9

I am pleased with student progress learning addition and subtraction facts. Everyday, I am amazed at the patterns they are able to find and use to help them remember the facts. We have been looking for tens when adding nine.

For example:

9 + 3 

If I take one from the 3 to make ten, I have 2 left over. 10 + 2 = 12.

Please enjoy videos of two of our students as they explain the strategy. Then, try it with your child!
