This is one of my students favorite activities throughout the year. This is the one I created for division. I've used the same template for variety of concepts.
How to use: My students sit in groups of four to complete this activity. They each work their own problem from the placemat. After they each have their answer, they will add up their answers to come up with one answer to be checked. If they are correct, they will move to the next level. The first time I tell them they are wrong, I will not tell them who is wrong. They learn to work together and to check one another's work. A majority of the time their adding is wrong not a student's answer. I do not use it as a race. My students just feel excited each time they level up because they know the higher the level the more "challenging" the problems.
Feel free to edit the template if the numbers do not meet your needs.
