This puzzle is to be cut up and students put it back together to look as shown. Easy answer key, since it should be a Fibonacci sequence when correctly put together. I recommend grouping algebra 2 students or precalculus students into groups of 2-4 to work collaboratively. All types of factoring: quadratics, quadratic form, sum and diff of cubes, diff of squares, grouping, GCF.
I recommend copying all puzzles on separate colors: that way if they get mixed up, you'll know which envelope to put in back into!
