Common Core Standards:

CCSS.Math.Content.HSA-APR.C.4 Prove polynomial identities and use them to describe numerical relationships. For example, the polynomial identity (x2 + y2)2 = (x2 – y2)2 + (2xy)2 can be used to generate Pythagorean triples.

CCSS.Math.Content.HSA-APR.C.5 Know and apply the Binomial Theorem for the expansion of (x + y)n in powers of x and y for a positive integer n, where x and y are any numbers, with coefficients determined for example by Pascal’s Triangle.

Targeted Needs of Student:

Gaining full mastery of the concept of binomials

Goal:

Helping students understand how to multiply binomials and trinomials

Materials Needed:

1.      Paper  

2.      Writing utensils

Explanation/Summary:

Teacher will present strategy and model how to use it. Students multiply the binomials outside of the box and record the corresponding answer in the inside boxes. Then, they will add the binomials and write the new trinomial. Students will set up strategy when solving problems for class work, homework, and tests.
