Help students master addition and subtraction algorithms with these reusable wipe-on/wipe-off math boards designed to support alternative strategies taught in Everyday Math. These structured templates guide students step-by-step through multi-digit computation using methods like partial sums, column addition, expand-and-trade subtraction, counting-up subtraction, and rounding with estimates.

Just slip each page into a sheet protector and use with dry erase markers for instant, repeatable math practice.

These boards act like “training wheels” for computation, helping students successfully execute each step of alternative addition and subtraction algorithms without getting lost in the process.

Perfect for whole group instruction, small groups, math intervention, and independent practice.

Why Teachers Love These Algorithm Boards

• Supports partial sums, column addition, expand-and-trade subtraction, and counting-up subtraction
• Reinforces rounding and estimating strategies
• Aligns with Everyday Mathematics alternative algorithms
• Provides built-in structure for multi-digit addition and subtraction
• Excellent for differentiation and math intervention
• Especially helpful for students with dysgraphia, dyscalculia, or visual-perceptual needs
• Easy for families to use at home when alternative algorithms feel unfamiliar

Clear layouts and guided formats help students focus on the math process instead of paper setup.

Each template includes a completed example so students can see exactly how each algorithm works.
