Help students remember the steps to the various algorithms for each operation with these easy to use posters!

Each poster has an example that is color-coded to correspond to the listed steps.

There are versions of each poster with and without a colored border (depending on your personal preference).

These are formatted for 8.5 x 11". There are also directions for how they can be printed to be large multi-page posters.

For each algorithm, bulletin board headings are also included.
