Quick overview

This free ratios worksheet for grades 6-7 targets unit rates and proportional reasoning skills.

Lesson plan snapshot

15-20 min
  • Warm-up (3 min): read and write ratios from quick prompts.
  • Model (5 min): solve the worked example together.
  • Guided practice (5 min): complete problems 1-3 as a group.
  • Independent practice (7 min): finish the remaining problems.

Materials: ratio table, pencil

Learning targets

  • Write ratios in multiple forms (a:b, a to b, a/b).
  • Find unit rates from tables and word problems.
  • Identify proportional relationships.

Step-by-step approach

  1. 1Write the ratio in the correct order (what to what?).
  2. 2Create a ratio table to scale by the same factor.
  3. 3Find unit rate by dividing both quantities by the same number.
  4. 4Check if the ratio stays constant across pairs.

Common mistakes

Mistake

Swapping the order of the ratio.

Try instead

Label each quantity and keep the order consistent.

Mistake

Treating ratios as part-to-whole by default.

Try instead

Clarify whether the ratio compares part-to-part or part-to-whole.

Mistake

Using inconsistent scaling factors.

Try instead

Multiply or divide both parts by the same number.

Worked example

Guided
A car travels 150 miles in 3 hours. What is the unit rate?
  1. Unit rate means per 1 hour.
  2. Divide both numbers by 3: 150 ÷ 3 = 50.
  3. The unit rate is 50 miles per hour.
Answer: 50 miles per hour

Teacher tips

  • THave students label units in every ratio table.
  • TUse real-world comparisons (recipes, speed, cost) to build meaning.
  • TAsk students to justify whether a relationship is proportional.

Parent tips

  • PCompare sports stats (points per game) to practice unit rates.
  • PKeep the order consistent: say the ratio out loud.
  • PUse shopping examples to compare cost per item.
