About this worksheet

What students practice

  • Students use properties of addition to regroup and simplify rational-number calculations.
  • Students rewrite subtraction of grouped rational numbers as addition of opposites.
  • Students apply equivalent expressions to compare and revise model dimensions.

How to use

Have students mark helpful pairs or rewrite subtraction before calculating. Use the final explanation to check how students handle subtracting a grouped sum.

Curriculum

3D-Printing Club: Rewrite Lab

Use equivalent expressions to simplify part and model calculations.

Design Rewrites

Keep each number's sign with it when reordering. Look for helpful pairs and whole-number sums.

1.
A model's width calculation is 18.6 + (−2.4) + 1.4 millimeters. Which rewrite splits −2.4 into two addends and then pairs opposites?
  • A. 18.6 + ((−2.4 + 1.4) + (−1))
  • B. 18.6 + ((−2.4 + 2.4) + 1.4)
  • C. 18.6 + ((−1.4 + 1.4) + 1)
  • D. 18.6 + ((−1.4 + 1.4) + (−1))
2.
Group terms with the same denominator to simplify this signed design adjustment.

7/12 + (−5/8) + 5/12 + (−3/8) =   mm

3.
Which rewrite correctly uses addition to reverse the order of the two terms in −3.2 − 1.7?
  • A. −1.7 + (−3.2)
  • B. −1.7 + 3.2
  • C. 1.7 + (−3.2)
  • D. 1.7 − (−3.2)
