About this worksheet

What students practice

  • Students use commutative, associative, and distributive properties to multiply rational numbers.
  • Students rewrite division as multiplication by a reciprocal to simplify rational-number quotients.
  • Students identify valid and invalid operation strategies in project progress calculations.

How to use

Use after introducing signed rational-number operations. Have students show a helpful rewrite beside each calculation, then discuss the final error analysis.

Curriculum

Common Core standard covered

7.NS.A.2.c

Coding Camp: Progress Calculation Strategies

Use properties to simplify rational-number products and quotients.

Strategy Tools

The coding camp dashboard tracks project progress. Choose or complete rewrites that make its calculations easier.

1.
A dashboard calculation is (−0.25 × 13) × 4. Which equivalent expression groups factors with a product of −1?
  • A. (0.25 × 4) × 13
  • B. (−0.25 × 13) + 4
  • C. (−0.25 × 4) × 13
  • D. (−0.25 + 4) × 13
2.
Two groups of unfinished tasks contribute −0.5 × 18 and −0.5 × 2 progress points. Use the distributive property to combine the products.

(−0.5 × 18) + (−0.5 × 2) = −0.5 × (18 + 2) =   points

3.
A progress formula includes (−7/8) ÷ (7/4). Which expression correctly rewrites the division as multiplication?
  • A. (−8/7) × (7/4)
  • B. (−7/8) × (7/4)
  • C. (−7/8) × (−4/7)
  • D. (−7/8) × (4/7)
