Pacing

This WebQuest is designed for one 45–60 minute class period. Students who finish early can explore the resources or attempt the extension challenge. A two-day version: Day 1 = Introduction through Process (Steps 1–4); Day 2 = Self-Check and Reflection.

Grouping Suggestion

Works well as individual work with optional pair-share on Step 3 (ratio tables). Consider think-pair-share before the self-check to let students compare unit rate strategies.

1. Introduction

You just opened the Berry Blast Smoothie Stand! 🍓🍌

Every great smoothie uses a ratio: how much of one thing compared to another. Example: 2 cups of berries for every 3 cups of milk. To set a fair price, you also need a unit rate: the cost for just 1 cup or 1 smoothie.

In this WebQuest, you will use ratios and unit rates to run your stand.

2. Task

3. Process

Do the steps in order. Read each one carefully.

  1. Step 1 — Learn the words

    Ratio = compares two amounts. Unit rate = the amount for exactly 1.

    Recipe ratio: 2 cups berries : 3 cups milk

  2. Step 2 — Play the 3D game

    Open the Smoothie Stand 3D game and mix smoothies using ratios. Try to fill at least 3 orders.

  3. Step 3 — Build a ratio table

    If 1 smoothie needs 2 berries, then 3 smoothies need 6 berries. Keep the ratio equal.

    Smoothies → Berries: 1→2, 2→4, 3→6, 4→8, 5→10

  4. Step 4 — Find unit rates

    If 4 smoothies cost $12, then 1 smoothie costs $12 ÷ 4 = $3.

    💡 Tip: "Per" means "for each 1." Miles per hour = miles for 1 hour.

5. Evaluation (Rubric)

Skill 4 — Expert 3 — Proficient 2 — Developing 1 — Beginning
Writing ratios (6.RP.A.1) Writes ratios correctly every time, in two forms (colon and fraction), with no errors. Writes ratios correctly most of the time in at least one form. Writes some ratios correctly; makes minor notation errors. Attempts to write ratios but needs significant help.
Unit rate (6.RP.A.2) Finds unit rate efficiently and correctly; can explain the strategy clearly. Finds the unit rate correctly with minor calculation errors. Finds the unit rate with a hint or guided step. Has not yet found a correct unit rate independently.
Ratio tables (6.RP.A.3) Builds complete equivalent ratio tables with no errors; recognizes pattern. Builds ratio tables with at most one error. Builds partial ratio tables; some ratios are equivalent. Ratio table incomplete or ratios are not equivalent.
Self-check score 90–100 % (4–5 correct) 75–89 % (4 correct) 50–74 % (2–3 correct) Below 50 % (0–1 correct)

6. Conclusion

Great work, smoothie boss! You can now write ratios, build ratio tables, and find unit rates to price your menu. These same skills help you with recipes, shopping deals, and speed problems. Complete the self-check below to show what you learned.

7. Interactive Self-Check

Try each question, then click Check to see instant feedback. Complete all 5, then use the Check My Answers button at the bottom to record your score.

Format: number:number — Example style: 5:7
Hint: divide total cost by number of smoothies.
Q3. Which ratio is equivalent to 2:4?
Use your ratio table from Step 3.
Divide: 60 ÷ 2 = ?

🔑 Teacher Answer Key (click to expand)
  1. Q1 — Ratio of berries to milk: 2:3 (berries 2, milk 3; colon form).
  2. Q2 — Unit rate for smoothies: $12 ÷ 4 = $3 per smoothie.
  3. Q3 — Equivalent ratio to 2:4: 1:2 (divide both by 2; 2÷2=1, 4÷2=2). Note: 2:6, 4:6, 3:4 are all incorrect because they do not simplify to the same ratio.
  4. Q4 — Bananas for 5 smoothies: 1 smoothie × 5 = 5 smoothies; 2 bananas × 5 = 10 bananas.
  5. Q5 — Unit rate (miles per hour): 60 ÷ 2 = 30 miles per hour.

Sample student reflection: "I learned that a unit rate tells me the cost or amount for exactly 1, which makes it easy to compare prices or scale a recipe."

8. Reflection
