Here’s the solution to the “Units of Time” worksheet, with explanations for each answer:
---
1. Making a cup of coffee.
✔ 1 minute
*Explanation:* Brewing or preparing a single cup of coffee (especially with a modern machine or instant coffee) typically takes about 1 minute. 1 second is too fast; 1 week is absurdly long.
---
2. Counting from 1 to 10.
✔ 10 seconds
*Explanation:* Most people can count from 1 to 10 in about 5–10 seconds. 10 minutes or 10 weeks are far too long — that would be extremely slow counting!
---
3. Go on a fishing trip.
✔ 3 days
*Explanation:* A typical recreational fishing trip lasts a day or a weekend — 3 days is reasonable for a short vacation. 3 years is way too long; 3 minutes is not enough time to even get to a fishing spot.
---
4. Writing on your diary.
✔ 15 minutes
*Explanation:* Writing an entry in a diary usually takes around 10–20 minutes — long enough to reflect and write a few paragraphs. 15 weeks or 15 hours are excessive for a daily journal entry.
---
5. Building a new bridge.
✔ 3 months
*Explanation:* While large bridges can take years, smaller or local bridges (like over a creek or road) can be built in a few months. 3 days is impossible; 3 minutes is ridiculous. For a Grade 2 context, 3 months is the most reasonable estimate among the choices.
*(Note: In reality, major bridges take years — but for this level, 3 months is the best choice given the options.)*
---
6. Taking a morning jog.
✔ 20 minutes
*Explanation:* A typical morning jog lasts 20–30 minutes. 20 seconds is barely enough to warm up; 20 months is absurd.
---
7. Filling up a water bottle.
✔ 20 seconds
*Explanation:* It takes just seconds to fill a standard water bottle from a tap or dispenser. 20 minutes or 20 hours is far too long.
---
8. Painting a house.
✔ 5 days
*Explanation:* Painting a whole house (interior and/or exterior) usually takes several days — 5 days is realistic for a small-to-medium house. 5 seconds is impossible; 5 years is way too long.
---
9. Having a summer holiday from school.
✔ 2 months
*Explanation:* Summer break in most countries lasts about 2 months (e.g., June–August). 2 years is too long; 2 days is just a weekend.
---
10. Learning a new language.
✔ 6 months
*Explanation:* While mastering a language takes years, learning basic conversational skills (as expected at Grade 2 level) can reasonably take 6 months with consistent practice. 6 minutes or 6 hours is impossible; 6 months is the most realistic among the choices.
