This is a game that can be used small group or individually. Students race to see who can reach the target number first by adding the surrounding numbers. For younger students, the numbers wouldn't have to touch. For a challenge, they should touch. For subtraction you can start at the target number and subtract to reach zero. Students can write their number sentences on the Witzzle strips provided.
This is a great way for older students to practice orders of operation. Students can use any method of math to solve their problem. The rules are really determined by the teacher!
This is a game you can purchase called Witzzle Pro. I did not create this game, I did create my own rules for the game.
