This is a set of 88 flash cards for factoring differences of squares. As I add more flash cards to this set, you will be notified of an update!

It goes through the list of

x^2 - 1 to x^2 - 256,
X^2 - 400 to x^2 - 8100 (perfect square hundred multiples)

Then each of the above with the coefficient of 4 and 9 in front of the x^2.
Then a set of x^2 - y^2 and numerous exponents and coefficients.

It is a good mix of everything!

This set is designed for a no-writing independent or partner practice.

I have a set of 233 flash cards for factoring trinomials that is similar to this set.

These are designed to print the same way as the trinomials: cardstock, laminate, cut, hole punch, and ring binder!
