This PowerPoint guides students through learning how to subtract polynomials using Algebra Tiles. This worked great in my classroom! I gave a set of Algebra Tiles to each student. I had the students model the problem along with me through the power point. Then I asked students to illustrate the model on their own paper. We then worked through solving the problem using the tiles and again algebraically by distributing the negative, recognizing and combining like terms. The PowerPoint includes 4 examples and a word problem. The day before I used the Adding Polynomials with Algebra Tiles PowerPoint and followed the same lesson plan. Quiz and Tests grades were great and students really enjoyed using the tiles!
