### Properties of Addition and Math Games

Man, this past week was just crazy busy. I have been wanting to sit down and blog for several days, but I haven't even had time to scratch my head!

Anyway, last week we talked about properties of addition. I found a great flipchart on promethean planet (it's at the bottom of the link page) to introduce the properties and then Friday, we used dice to model the commutative and associative properties.

I had them draw a T chart with one side labeled commutative property and the other associative property. We spent about 10 minutes rolling two dice and writing the numbers two ways. Example: you roll a 5 and a 4. Students would then write 5 + 4 = 4 + 5 or you can have them write 5 + 4 = 9 and 4 +5 = 0.

After practicing the commutative property, we rolled three dice and worked on the associative property. Example: you roll 4, 3, and 1. Students would write (4 + 3) + 1 = 4 + (3 + 1) or they could write (4 + 3) + 1 = 8 and 4 + (3 + 1 ) = 8.

We didn't do much with the Indentity Property the second day everyone understood the idea that when you add 0 to a number, it stays the same.

Here is a link to some addition and subtraction games to help your students work on different skills. The only gameboard I don't have in the file is the Spin a Number board. I will try to scan it next week and post it for you kinder teachers.

These are some great Computer games for helping your kids practice addition and subtraction.

1. Those are some awesome games! Thanks so much for the link :). I love how math has such great potential to be hands-on!

2. Math isn't my strong suit - so many great ideas! Thank you!

3. thanks I'm using these as a new teacher!

4. thank you so much for sharing. Love it.

5. Thanks for the idea. Just what I need for 4th graders.

6. Thank you for sharing these great ideas!
