money each has.

2. In a math game, Hakeem has to choose a number that is
greater than 7.923 and less than 7.929. What must the digit in the
hundredths place be in the number he chooses? Explain.The digit
in the hundredths place must be a 2. Both of the original numbers
have a 2 in the hundredths place, so the only way to make a
number be less than 7.929 and greater than 7.923 is to change
the digits in the thousandths place, ten-thousandths place, etc.

problems. Use working backwards and drawing a picture
1) 24 x 103 = 24,000
to help you solve this problem.
1. Mrs. Stokes graded one-half of her students’ papers on
Friday. She graded 18 more on Saturday. Then there
2) 4.785 x 1,000 = 4,785
were only 14 more papers to grade on Sunday. How many
papers did Mrs. Stokes need to grade over the entire
weekend? 14 + 18 = 32. 32 x 2 = 64 total papers.
3) 19.473 ÷ 100 = 0.19473
(working forward to check: 64 ÷ 2 = 32. 32 – 18 = 14)
2. Jax bought some bottles of water. He drank 1 of the
bottles. Then he bought 5 more bottles and drank 3 of

those. He has 4 bottles left. How many bottles did he
have at the start? 4 + 3 – 5 + 1 = 3 bottles that he 1st
bought. (working forward to check: 3 – 1 + 5 – 3 = 4
5) 956.237 x 105 = 95,623,700
bottles left)
3. Mrs. Stokes weighed a bag of grapes. She added 2
pounds of grapes to the bag. After she took out 3 pounds
6) 1.791 ÷ 1,000 = 0.001791
of grapes the bag weighed 4 pounds. How much did the
bag of grapes weigh at the start? 4 lbs + 3 lbs – 2 lbs = 5
lbs (working forward to check: 5 lbs + 2 lbs – 3 lbs = 4 lbs)

her $5. Then Chloe had $7. How much money did Chloe
have when she arrived at the craft store? $7 - $5 + $4 + $6 8) 97.089 x 10 = 970.89
= $12 to start (working forward: $12 - $6 - $4 + $5 = $7)
