by Don Balka, Laurie Boswell Newly revised and updated for the current Math Standards, this popular title is a complete resource for helping students visualize the algebraic process. Students model math problems with algebra tiles to build and solve equations while gaining comfort and skill with algebraic expressions. Teacher's notes and reproducible activities cover integer operations, linear and quadratic expressions, perimeter, arrays, binomials and more. Each topic progresses through: objective, prerequisites, getting started and closing the activity.
