This is Math Dash- an addition and subtraction game played like Sequence (add the numbers on the card and then find the sum on the game board, whoever gets four in a row first wins) and the other is a 4x4 ft 100 chart. Both very affordable and super fun!

First we played by just adding the dice and seeing who got to 100 first and then I covered the frames with white and they had to guess which numbers were under the frames.
My son used this homemade rekenrek to add. It's just a piece of foam board from the dollar store 2 pipe cleaners and 20 beads. You can make a whole class set out of 2 pieces of foam board so they are very inexpensive to make with your whole class.
This is the back...not pretty but functional:)
