Do your students struggle to successfully execute the many steps required to solve a addition and subtraction problems using the alternative algorithms taught in Everyday Mathematics? These wipe on/wipe off boards are exactly what you need. Just add page protectors and dry erase markers and your students will be adding and subtracting with ease in no time.

• I use these templates to introduce the addition and subtraction algorithms to my students. I call them “training wheels” because they guide students through the many steps.
• The templates are perfect for differentiation! They are particularly helpful for students with dysgraphia, dyscalculia, and visual perceptual deficits, as the provide the correct format in which to set up the algorithm.
• These templates are particularly helpful to place inside of a sheet protector for students to bring home. Most parents are unfamiliar and often stumped by these algorithms so not only will the templates help your students, they will also assist parents!
• The simple, clear directions and templates will help your students understand the steps and structure of solving multidigit addition and subtraction problems.
