  1. Geometric Measurement and Data (for third grade) Emily Longman February 12, 2014

  2. Multiplication and Addition of Area Tiling Multiplication Addition

  3. Remember: In the last lesson, we learned that area can be measured using unit squares. 1 unit 1 unit

  4. Tiling You can visualize unit squares by using tiles, like this one. Click here to see how.

  5. Click on the red unit squares (tiles) and watch how they cover the entire surface of the rectangle.

  6. Click on the red unit squares (tiles) and watch how they cover the entire surface of the rectangle. You can add up the tiles you used – that number is your area: Six tiles fit into this rectangle.

  7. multiplication You can also multiply the side lengths to find the area: 3 unit squares x 2 unit squares = 6 square units

  8. Use the multiplicative property of area to find the area of the following examples. Click on the correct answer:

  9. 9 25 20 16

  10. Yes! 5 x 4 = 20 units squared

  11. No

  12. 5 x 4 = 20 units squared

  13. 6 4 3 2

  14. Yes! 3 x 2 = 6 units squared

  15. No

  16. 3x 2 = 6 units squared

  17. 8 3 9 5

  18. Yes! 3 x 3 = 9 units squared

  19. No

  20. 3x 3 = 9units squared

  21. 6 4 10 5

  22. Yes! 5 x 1 = 5 units squared

  23. No

  24. 5 x 1 = 5units squared
