What is the answer to 9,000 x 7?
63,000
Estimate to the nearest thousand and write the answer. 756 x 3
800 x 3 = 2,400
45,234 x 8
(40,000 x 8) + (5,000 x 8) + (200 x 8) + (30 x 8) + (4 x 8)

125 x 3
Teacher will show the correct answer on paper or whiteboard
Connor had 49 erasers. Jack had 7 times as many as Connor. How many erasers did Jack have? Write an equation and solve the problem.
49 x 7 = n
n = 343
What is the correct way to use compensation for 198 x 3?
198 +2 = 200
200 x 3 = 600
2 x 3 = 6
600 - 6 = 594
Estimate the nearest thousand and is the answer reasonable or not reasonable.
3,467 x 3 = 10,401
3,000 x 3 = 9,000
reasonable
Complete an area model for 28 x 2 and solve the problem.
Teacher will show correct answer on paper or whiteboard.
Draw an array for 210 x 4
Teacher will show the correct answer on whiteboard or piece of paper
Kelsey and Sophie went to the store. Sophie bought 10 apples and Kelsey bought 26. Tony bought 3 times more than Kelsey and Sophie combined. Write and solve an equation.
10 + 26 = 36
36 x 3 = n
n = 108
What is the correct way to use compensation? 292 x 4
292 + 8 = 300
300 x 4 = 1,200
8 x 4 = 32
1,200 - 32 = 1,168
Is it reasonable or not reasonable?
456 x 2 = 912
5,000 x 2 = 10,000
not reasonable
