14. Choose the best estimate for the problem shown.

A) 170 +30 =200
B) 200 +30 = 230

15. Solve the problem now.

A) 197
B) 198
C) 199

16. Choose the best estimate for the problem.

A) 100 -40 = 60
B) 80 - 40 = 40

17. Solve the problem now.

A) 45
B) 47
C) 46

18. Is 80 - 40 =40 a good estimate?

A) Yes, because I estimated the answer would be 40 and the actual answer was 46.
B) No because 40 + 40 is not 46.

19. Choose the best estimate for the problem.

A) 400 + 100 = 500
B) 300 +100 = 400

20. Solve the problem now.

A) 533
B) 531

B) ten rows with 3 in each row

31. Solve. 3 x 10 = ?

A) 13
B) 20
C) 30

32. If you drew an array for 3 x 10, what would it look like?

A) three rows with 10 in each row
B) ten rows with 3 in each row

33. How does drawing arrays for these fact pairs help you to understand the turn around rule?

A) It does not matter how you draw the dots.
B) The number of dots is the same on the pictures. This means the answers will be the same.

34. Which number sentence matches the array?
