✏️ Part 2: Short Answer — Solve problems with rational numbers

I can: Use rational numbers (fractions, decimals, negatives) to solve problems, including cases involving surface area and volume.

Success criteria: I can write an expression, perform operations with rational numbers, and give an answer in simplest form or a labeled decimal.

Differentiation strategies: Provide fraction-decimal conversion supports, allow calculators for arithmetic where needed, and give step prompts for students who need them.

Extension: Create a real-world problem using rational dimensions and find exact surface area and volume; justify choices and units.

Dyslexia-friendly option: Read problems aloud, use larger spacing, and highlight key numbers; allow oral responses if needed.

5. Compute: (-3/4) ÷ (1/2). Show your work and write the answer in simplest form.
6. A small box measures 2.5 in by 1 1/2 in by 4/5 in. Find its volume in cubic inches. Show calculation and final value with units.
7. Find the total surface area of a rectangular prism with length 7/2 ft, width 5/3 ft, and height 2 ft. Give an exact answer as a fraction (square feet) and a decimal rounded to two decimal places.
8. A runner does 3 3/4 miles on Monday and 2.6 miles on Tuesday. How many miles did they run in total? Show the sum.

🧭 Part 3: Reflection & Extension

9. Extension challenge: Design a rectangular prism using only rational-number dimensions (mix of fractions and decimals). Write the dimensions, then calculate both volume and surface area. Show work.
10. Reflection: Which part of solving rational-number problems was easiest for you and which part was most challenging? Describe one strategy you will use next time.
