  10. COMPENSATION 52 - 37 Add 3 to each number 15 55 40 52 37

  11. MULTIPLICATION

  12. How would you do this problem? 15 x 16

  13. What is the most efficient way to count these squares? You know your mutliplication facts up to the 10's

  14. 10 6 100 60 10 50 30 5

  15. MULTIPLICATION 15 
x 16 30 60 50 100 240 (6 x 5) (6 x 10) (10 x 5) (10 x 10)
