Here's the solution to the “Units of Time” worksheet, with explanations for each choice:
---
1. Making a cup of coffee.
✔ 1 minute
*Explanation:* Brewing a cup of coffee (especially with a modern machine or instant coffee) typically takes about 1 minute. It’s not 1 second (too fast) or 1 week (way too long).
---
2. Counting from 1 to 10.
✔ 10 seconds
*Explanation:* Counting aloud from 1 to 10 takes roughly 10 seconds at a normal pace. 10 minutes is too slow; 10 weeks is absurd.
---
3. Go on a fishing trip.
✔ 3 days
*Explanation:* A typical recreational fishing trip lasts a day or several days — 3 days is reasonable. 3 years is excessive; 3 minutes is far too short to even get to the water.
---
4. Writing on your diary.
✔ 15 minutes
*Explanation:* Writing an entry in a diary usually takes 10–20 minutes. 15 minutes is realistic. 15 weeks or 15 hours are way too long for a single diary 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) might be built in a few months. Among the options, 3 months is the most reasonable. 3 days is impossible; 3 minutes is nonsense.
> *Note: In reality, major bridges take years, but for Grade 2 level, “3 months” is the best estimate among the choices.*
---
6. Taking a morning jog.
✔ 20 minutes
*Explanation:* A typical morning jog lasts around 20–30 minutes. 20 seconds is too short; 20 months is ridiculous.
---
7. Filling up a water bottle.
✔ 20 seconds
*Explanation:* Pouring water into a bottle takes just a few seconds — 20 seconds is a safe, slightly generous estimate. 20 minutes or 20 hours are wildly inaccurate.
---
8. Painting a house.
✔ 5 days
*Explanation:* Painting a whole house (interior and exterior) usually takes several days to a week. 5 days is reasonable. 5 seconds is impossible; 5 years is extreme overestimation.
---
9. Having a summer holiday from school.
✔ 2 months
*Explanation:* Summer break in most countries lasts about 2 months (June–August). 2 years is too long; 2 days is too short.
---
10. Learning a new language.
✔ 6 months
*Explanation:* While becoming fluent takes years, learning basic conversational skills in a new language can reasonably take 6 months with consistent study. 6 minutes or 6 hours are far too short.
---
