Manipulatives: Algebra Tiles. (College)
We are going to use algebra tiles to develop some of the ideas for FOILing and multiplying polynomials. If you would like to access a set of algebra tiles online, go to this website, Select "Grade 8" for your grade and "Algebra Tiles" for your manipulatives, and you will have access to an online set of algebra tiles like we used in class on 3/19.
