Critical Thinking Worksheet Grades 3-5: Recipes | Education World - Free Printable

Let's solve each question based on the passage "16—The Best Pancake Recipe".

Question 1:

Give the number of the sentence that tells you how many friends are coming to the slumber party. How many friends are coming?

- Look at sentence 1: *"Olga is having eleven friends over for a slumber party."*
- This sentence directly states that eleven friends are coming.

✔ Answer:
- Sentence number: 1
- Number of friends: 11

Question 2:

If each person eats 3 pancakes, how many people can eat from this recipe? Give the number of the sentence that provides the best evidence for your answer.

- The recipe makes nine 4-inch pancakes, as stated in sentence 5:
> "Makes nine 4-inch pancakes (serves 3–4 people)."

- But we need to calculate based on each person eating 3 pancakes.

- Total pancakes = 9
- Each person eats 3 → So, number of people = 9 ÷ 3 = 3 people

- However, the recipe says it serves 3–4 people, which supports that 3 people could each have 3 pancakes (total 9), or possibly 4 people with fewer.

But since the question asks how many people can eat if each eats 3 pancakes, we go by total pancakes:

> 9 pancakes ÷ 3 pancakes per person = 3 people

- The best evidence is sentence 5, because it tells us how many pancakes the recipe makes and how many people it serves.

✔ Answer:
- Number of people: 3
- Sentence number: 5

Question 3:

If Olga’s mom including Olga eats 3 pancakes, how many pancakes should Olga make?

- First, clarify: “Olga’s mom including Olga” means two people — Olga and her mom.
- Each eats 3 pancakes → 2 × 3 = 6 pancakes needed for them.
- But the original recipe makes 9 pancakes.
- That would be enough for them plus one more person (since 9 - 6 = 3 pancakes left).
- But the question is asking: how many pancakes should Olga make?

Wait — she’s making pancakes for her friends (11) and possibly herself and her mom.

Let’s re-read the context:

- She is having 11 friends over.
- She wants to make pancakes for the party.
- The recipe serves 3–4 people and makes 9 pancakes.

So, if each person (including Olga and her mom) eats 3 pancakes, then:

- Total people = 11 friends + Olga + her mom = 13 people
- Each eats 3 pancakes → 13 × 3 = 39 pancakes needed

Now, the original recipe makes 9 pancakes, so we need to scale up.

But the question is: How many pancakes should Olga make?

We don’t know how many pancakes per person are required beyond what’s implied — but the scenario says each person eats 3 pancakes, so we use that.

Total pancakes needed = 13 people × 3 = 39 pancakes

✔ Answer:
- 39 pancakes

Question 4:

By how much should Olga multiply this recipe to have enough pancakes? Use a complete sentence.

- Original recipe makes 9 pancakes.
- She needs 39 pancakes.
- So, multiplication factor = 39 ÷ 9 = 4.333... → about 4⅓ times

But recipes are usually multiplied by whole numbers or simple fractions.

Let’s check:

- 4 × 9 = 36 pancakes → not enough
- 5 × 9 = 45 pancakes → enough

So, multiply by 5 to get 45 pancakes, which is enough for 13 people eating 3 each (39 needed).

Alternatively, if she wants exactly 39, she could multiply by 4⅓, but that’s messy.

But the question asks by how much should she multiply to have enough pancakes.

So, she should multiply the recipe by 5 to have enough pancakes.

✔ Answer (complete sentence):
Olga should multiply the recipe by 5 to have enough pancakes for everyone.

---

✔ Final Answers:

1. Sentence 1; 11 friends
2. 3 people; Sentence 5
3. 39 pancakes
4. Olga should multiply the recipe by 5 to have enough pancakes for everyone.
