  • Pass out the template, BLM 6.14, and scissors.
  • Cut Rectangle A into rows and complete Problem 1. Share your responses and thinking with your partner.
  • Cut Rectangle B into columns and complete Problem 2. Share again.
  • Put both rectangles back together again.
concept development1
Concept Development
  • Move the columns of Rectangle B so they are sitting directly on top of the rows of Rectangle A with no gaps or overlaps.
  • Talk to your partner about what you notice.
  • They both show the same amount, and they’re both the same size and shape.
  • We can see the same rectangle different ways: it’s 2 rows of 4, 4 columns of 2 or, 8 squares.
  • You’ve recognized that we can decompose the same rectangle into rows, columns or unit squares.
concept development2
Concept Development
  • Take both your rows of 4 and cut them to show 4 twos instead of 2 fours.
  • Imagine we were going to put 2 rows on top to make the exact same rectangle. Talk to your partner.
  • Explain what those rectangles would be.
  • It would be 2 rows of 8. They would be 2 of the long skinny rectangles.
  • We can decompose this rectangle into 2 rows of 8 or 8 columns of 2.

Concept Development
  • Cut out all your squares from Rectangles A and B.
