Headache!

The First Graders learned a card game called "Headache" to practice fact families. Two players place a card on their foreheads. The third player tells them their total. The two players look at each other and use the other's card and the total to figure out what number is on their own foreheads.

The total is 10!
The player on the right may be thinking "8+ ___=10" to figure out his number.
The player on the left may be thinking "10- ___=2" to figure out her number.


Getting comfy to apply what we learned in our math journals
