Let's solve the
"Estimating Capacities" worksheet step by step. The goal is to
tick the better estimate for the capacity of each object, choosing between two options — one in milliliters (ml) and one in liters (L). Remember:
-
1 liter (L) = 1000 milliliters (ml)
- So,
1 ml is very small, while
1 L is a reasonable amount for a bottle or cup.

🔹 1. Baby Bottle
- Options:
250 ml or
250 L
- A baby bottle holds a small amount of milk.
-
250 L is like filling a large swimming pool — way too much!
-
✔ Correct answer: 250 ml
---
🔹 2. Ketchup Bottle
- Options:
300 ml or
300 L
- A typical ketchup bottle is about the size of a small condiment container.
-
300 L is enormous — that’s more than a bathtub!
-
✔ Correct answer: 300 ml
---
🔹 3. Water Bottle
- Options:
1 ml or
1 L
- A standard plastic water bottle holds about
500 ml to 1 L.
-
1 ml is just a few drops — far too little.
-
✔ Correct answer: 1 L
---
🔹 4. Watering Can
- Options:
3 L or
3 ml
- A small watering can used for plants typically holds several liters.
-
3 ml is less than a teaspoon — impossible for a watering can.
-
✔ Correct answer: 3 L
---
🔹 5. Soda Can
- Options:
150 ml or
150 L
- A standard soda can is about
330 ml, but
150 ml is close enough for estimation.
-
150 L is huge — equivalent to 150 bottles of water!
-
✔ Correct answer: 150 ml
---
🔹 6. Coffee Mug
- Options:
100 ml or
100 L
- A regular mug holds about
200–300 ml, so
100 ml is a bit small but still reasonable as an estimate.
-
100 L is absurd — that’s more than a barrel!
-
✔ Correct answer: 100 ml
---
✔ Final Answers:
| Object | Better Estimate |
|--------------------|------------------|
| Baby Bottle | 250 ml |
| Ketchup Bottle | 300 ml |
| Water Bottle | 1 L |
| Watering Can | 3 L |
| Soda Can | 150 ml |
| Coffee Mug | 100 ml |
> 🟩 Tick the boxes next to the correct estimates!

💡 Tip:
Always think about real-life sizes:
-
ml → small amounts (like medicine, juice box, cup)
-
L → larger containers (bottles, jugs, buckets)
