Pacing Guide

Grouping

Engage: pairs or triads. Explore: individual with partner talk. Apply: individual. Reflect: individual, then optional share.

Differentiation — Support
  • Provide a fraction bar / ratio table graphic organizer.
  • Allow calculators for computation; focus on the concept.
  • Pre-teach "compare" and "per" with a picture card.
  • Pair with a stronger partner during Explore.
Differentiation — Challenge
  • Ask students to write their own unit-rate scenario and solve it.
  • Extend: compare unit rates across three options (best-buy task).
  • Introduce a double number line for equivalent ratios.

ESOL / Language Supports

1 Engage

You run a smoothie stand. A recipe uses 2 cups of mango for every 3 cups of ice.

Think: If you double the recipe, how much mango and ice do you need? Share your answer with a partner.

A ratio compares two amounts. Today you will use ratios and unit rates to run your stand smartly!

2 Explore

Open one link. Play and look for ratios. Then come back to this page.

After you explore, write one ratio you noticed below (optional):

3 Explain

Ratio: a comparison of two amounts. Example: 2 to 3, written 2:3 or 2/3.
Rate: a ratio that compares two different units. Example: 60 miles in 2 hours.
Unit rate: the rate for exactly 1 of something. Example: 30 miles per 1 hour.
Equivalent ratios: different ratios that name the same comparison. Example: 2:3 = 4:6 = 6:9.

Worked example. A pack has 12 cups for $4.

Unit rate (price per 1 cup) = $4 ÷ 12 cups = $0.33 per cup.

Unit rate (cups per $1) = 12 ÷ 4 = 3 cups per dollar.

Equivalent ratio check: 2:3 is the same as 4:6 — multiply both parts by 2.

To find a unit rate: divide the top number by the bottom number (get 1 on the bottom).

Q4. The mango:ice ratio is 2:3. If you use 4 cups of mango, how many cups of ice do you need?
Q5. A blender makes 10 cups in 5 minutes. What is the unit rate (cups per 1 minute)?
Teacher Answer Key (click to reveal)
  1. Q1. 2:3 — also accepted: 2 to 3 or 2/3 as a ratio.
  2. Q2. 2 — 8 ÷ 4 = 2 strawberries per smoothie.
  3. Q3. $2 — $12 ÷ 6 cups = $2 per cup.
  4. Q4. 6 — 2:3 = 4:6; multiply both by 2.
  5. Q5. 2 cups/min — 10 ÷ 5 = 2.
  6. Q6. 0.20 — $3 ÷ 15 = $0.20 per orange.

Sample reflection — R1: "A unit rate tells you the amount for exactly 1 of something, like cost per 1 item or miles per 1 hour." R2: Accept any real-world context: grocery shopping, cooking, speed, etc.

Rubric — Ratios & Unit Rates

Level Score What it looks like
Exceeds (4) 6/6 All answers correct; reflection uses precise vocabulary (ratio, rate, unit rate, equivalent); real-life example is detailed and accurate.
Meets (3) 4–5/6 Most answers correct; minor errors in notation or arithmetic; reflection clearly explains the concept in own words.
Approaching (2) 2–3/6 Some correct answers; confuses ratio with rate or struggles with equivalent ratios; reflection is brief or partially accurate.
Beginning (1) 0–1/6 Most answers missing or incorrect; little or no reflection; needs reteaching of ratio concept and unit rate procedure.

5 Reflect

Write 1–2 complete sentences for each prompt. Think carefully — use the vocabulary words.
