Students will practice factoring polynomials with this set of Mystery Number Activities. This set contains versions 1-10 and is most appropriate for an Algebra 1 level class.

Students completely factor the polynomials in each row. If done correctly, there is a common binomial factor in each row. They record this common binomial, then use the common binomials to create a mystery expression that will reveal a mystery number at the end.
