A few months ago, I came up with this game for Big Brother and I to play and practice math facts at the same time. It's been a big hit on weekends and vacations since then, and he's not even realizing he's building his number facts as we play.
What are number facts? Addition number facts are typically thought of as addition facts with a sum (answer) up to 20.
The rules to our "Show Down" game are very similar to the traditional card game "War" with a few math twists. The materials are relatively simple: a deck of playing cards, a sheet of paper, and a marker or pencil.
