About this resource
A complete lesson that teaches two-digit by two-digit multiplication through area models, so students understand why the partial products work before they use the standard algorithm.
Students break numbers into tens and ones, draw rectangles, find four partial products, estimate to check their work, and connect the model to the algorithm. Spot-the-mistake and word-problem pages build reasoning, and an exit ticket helps you decide who needs more support.
Prints cleanly in black and white.
Why teachers use it
- Builds the “why” behind multi-digit multiplication
- Connects area models to the standard algorithm
- Estimation practice on every problem set
- Spot-the-mistake page for reasoning and error analysis
- Teacher guide with scripts, misconceptions, and next steps
Questions
Which grade level is this?
Fourth grade (CCSS 4.NBT.B.5), and a useful review for grade 5.
Does it teach the standard algorithm?
It builds understanding with area models and shows how the same partial products appear in the standard algorithm on Page 5. A full algorithm lesson is a good follow-up.
Do I need base-ten blocks?
No, but they help students who need support.
