How to use it at home and in class
At home
Draw the rectangle on squared paper and count the squares to check the multiplication. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Adding the sides instead of multiplying.
- Leaving out the square units.
What to practice before and after area of rectangles
- Before: perimeter. If this sheet is a struggle, go back a step.
- After: area of triangles, once this one is mostly right.
- Learn it first: the area of rectangles lesson and the perimeter and area chart.
