Description
Students often struggle with traditional strategies for computing sums, differences, products, and quotients. The lattice method provides a time-tested alternative for success. Lattices can be used as a new tool for struggling students or an extension showing other ways to perform the four basic operations. You’ll find some students show much greater success using these simple strategies. Even operations with decimals are included.
