I don’t typically post math printables, but I wanted to share a dice game I made for ALuv (currently almost 7 years old) to review fact families and work in some more dice games (since this seemed to be our theme last week).
Now, I’m not a math guru, so I don’t know all the official terms for why fact families are important to teach. 
But basically, fact families help students to see how addition and subtraction are related to one another. (For example: If 6+4=10, then 4+6=10. Furthermore, if 10-6=4, then 10-4=6.)

Thanks for this maths game. I’m going to try it with my boys as we are working on maths facts at the moment.
If you’d like another maths dice game, this is one we enjoy playing …http://storiesandchildren.com/the-maths-squares-game/
Again, thanks heaps for your time in sharing your Fact Family Triangle.
This reminds me of a literacy game from Annie Moffatt. LOVE IT. I pinned it to my math board.
I like that you put the page in a page protector so you could use it again and again! Great idea!

Thanks!
One reason that these kind of activities are important is that they help students think about math in different ways (i.e., instead of thinking 5+5=10, they think 4+6=10, 3+7=10, -1+11=10, etc.), which in turn makes math more interesting.
