This quick-paced, nail-biter of a math game will leave your kids BEGGING for more! Team up to knock out the other team's player. The last team standing wins! This is by far the most engaging thing I've done for my classroom this year. My kids get SO excited when we play, and they work super hard all week practicing their math facts just so they can improve their Knockout game!

Not only is this great for learning math facts, but it builds character as it emphasizes teamwork and good sportsmanship.

A quick look at Knockout & how it is played:
•Divide your class into 2 single file lines
•Display the first slide
•The player at the front of his/her line faces off against the player from the other team: the first player to answer his/her question correctly wins and returns to the end of the line.
•The player who does not win goes to sit on the team "bench" to cheer on the team!

BUT WAIT. That's not all. If a player faces these slides, the following could happen:
•Knockout/Free Pass: One player gets knocked out, the other stays in the game!
•Double Free Pass: Both players automatically get to stay in the game!
•Double Knockout: Both players are automatically out!
•Pick a Pal: Choose a player from the bench to return to the game!

The team with players standing at the end of the game wins. In our classroom, we like to keep teams the same for a week or two and keep a running score as a Knockout "tournament."

This is a set of PowerPoint files and can be used any any device that supports PowerPoint.
