The Box Method (Area Model for Large Numbers)
To multiply 24 × 36, students will draw a 2x2 grid, break the numbers down by place value (20+4 and 30+6), and multiply the intersecting boxes. This visual method reduces working memory load and prevents the common errors associated with the traditional carrying algorithm.
If your 4th grader is taking a long time on homework, check if they are getting stuck on the basic facts (like 6×7) or the actual multi-digit procedure. Usually, it's the basic facts slowing them down.
Ensure your 4th grader is completely fluent. Challenge them with our Speed Test!
