Expressions and area

Target: Evaluate a side length and then find area.

Language target: Name the side before the area.

Likely miss: Students add the side pieces instead of multiplying.

Ask: What is the length of each side?

If you see it: The side length is a sum. Area multiplies the side lengths.

Evidence to listen for: Both the expression and the area are present.

Next: Sketch the rectangle with the expression labeled on one side.
