Main Idea Worksheets & Facts for Kids | Identifying it + Examples - Free Printable

Let's solve this worksheet step by step. The goal is to complete the outline by choosing the correct details from the box at the bottom and placing them in the appropriate blanks.

Step 1: Understand the Main Ideas

We have four main ideas (I, II, III, IV), each with supporting details (A, B, C). We need to match the correct detail from the box below to each blank.

---

Box of Details (Available Choices):

- They hope to reduce acne.
- Some have an allergy.
- Soy milk has more protein.
- Oat milk has a mild, creamy flavor.
- It reduces the risk of cardiovascular disease.
- It makes the bones stronger.
- It is a good source of choline.

---

Now, let’s go through each section:

---

I. Milk is a good source of nutrition.

- A. It gives calcium to the body.
- B. It contains potassium.
- C. _______________

This section is about nutritional content of milk.

Looking at the options:
- "It makes the bones stronger" → related to calcium, so fits here.
- "It is a good source of choline" → also a nutrient.
- But we already have calcium and potassium listed.

So, the best fit for C is:
✔ It is a good source of choline.

> Choline is a nutrient found in milk, and it's not mentioned yet.

II. Milk has health benefits.

- A. It is good for the brain.
- B. _______________
- C. _______________

Health benefits — what are the other health-related facts?

From the box:
- "It reduces the risk of cardiovascular disease." → health benefit
- "It makes the bones stronger" → already used? Wait — actually, that one might be better under nutrition, but it's also a health benefit.

But note: “It makes the bones stronger” is likely linked to calcium, which is nutritional, but can also be considered a health benefit.

However, we already used "It makes the bones stronger" in part I? No — wait, we didn’t use it yet.

Wait — we did use “It makes the bones stronger” as a possible choice.

But let's check: Is it better under nutrition or health?

- Nutrition: What milk *contains* (calcium, potassium, choline)
- Health: What milk *does* for your body (strengthens bones, helps brain, reduces disease)

So both sections could use it, but since "gives calcium" is already listed under nutrition, then "makes bones stronger" is a health benefit.

So:
- A. It is good for the brain. → already given
- B. It makes the bones stronger. ✔
- C. It reduces the risk of cardiovascular disease. ✔

These are both health benefits.

So:
- B: It makes the bones stronger.
- C: It reduces the risk of cardiovascular disease.

III. Some people do not consume milk.

- A. _______________
- B. Some follow a specific diet.
- C. _______________

Why don’t some people drink milk?

Options:
- "Some have an allergy." → yes, common reason
- "They hope to reduce acne." → possible, but less common
- Others are about alternatives, not reasons for avoiding milk.

So:
- A: Some have an allergy. ✔
- C: They hope to reduce acne. ✔

Note: "They hope to reduce acne" is a reason why someone might avoid milk — some believe dairy causes acne.

So:
- A: Some have an allergy.
- C: They hope to reduce acne.

(Or vice versa? Let's see — B is already "Some follow a specific diet," so A and C are two other reasons.)

Yes, both make sense.

---

IV. Experts have discovered different sources of healthy milk.

- A. Almond milk is an effective alternative for children and adults.
- B. _______________
- C. _______________

This is about alternatives to cow’s milk.

Options left:
- "Soy milk has more protein."
- "Oat milk has a mild, creamy flavor."

These are descriptions of plant-based milks.

So:
- B: Soy milk has more protein.
- C: Oat milk has a mild, creamy flavor.

Perfect.

#### I. Milk is a good source of nutrition.
