I did this with my Algebra I class and it was a hit. I post those paper around the classroom. There are 18 problems total on 18 pieces of paper. Top is the problem and bottom is the answer to another problem. Kids are supposed to pick a number to start solving the problem on top, and use their answer to lead them to the next problem, by matching their answer to all the answers on the bottom of a page. By the end they should have the same sequence of number, regardless of what number they start with.
If you purchase this item, I will send you the sequence as the KEY.
