Are you looking for a way to help students truly see what’s happening when they add multi-digit numbers? One powerful approach uses place value-based strategies that build from representational thinking toward more efficient, abstract methods.
Start with Expanded Form
In the first part of the video, I model a place value strategy using expanded form. Students break apart each number into hundreds, tens, and ones, add those values separately, and then combine their sums.
This representational method supports flexible thinking and strengthens their understanding of how numbers work. It also lays a strong foundation for future strategies that depend on place value fluency.
Scaffold Toward the Algorithm
Next, I introduce a slightly more advanced approach that continues to use the Hundreds Chart as a scaffold. This visual support helps students begin to internalize regrouping and transitions them toward the traditional addition algorithm, a 4th-grade standard.
This shift is intentional. By gradually moving from expanded form to a structure that supports the algorithm, students develop a deeper understanding of why the algorithm works—not just how to use it.
Support with Consistent Structure
The real power of MathReps lies in their consistency. Each template reinforces key math skills in a familiar format, allowing students to focus on developing strategies and precision rather than navigating new instructions each time.
Whether students are practicing during warm-ups, small groups, or independent work, MathReps create a rhythm of reflection and growth with immediate feedback.
Grab the Free Templates
The MathReps template shown in the video is available for free at MathReps.com. And if you’re looking for a reusable option, check out the dry-erase Wipebook versions—perfect for centers, partner work, or teacher modeling.
One Rep at a Time
With MathReps, you’re not just assigning practice—you’re building confidence, one rep at a time.
