This is a Connect Four (BINGO style) game with the following:
16 task cards:
4 - just finding tax
4 - just finding discount
4 - calculating discount & tax
4 - percent of change (increase and decrease)
4 different game boards - enough for small group play
I would print these on card stock and laminate the game boards so students can check off using dry erase markers.
My students love this type of game, and because it is self-checking, the answers on the back, I can easily monitor and facilitate their learning.
