Measurement Worksheets | Free - Distance Learning, worksheets and ... - Free Printable

Let's solve each question in the worksheet "Estimating Distance (Metric)" step by step. The goal is to choose the best estimate for the length or height of each object using metric units: millimeters (mm), centimeters (cm), meters (m), and kilometers (km).

1) Ferris Wheel

- A Ferris wheel is a large amusement ride.
- Typical Ferris wheels are tens of meters tall.
- For example, the London Eye is about 135 meters tall.
- But here, we’re choosing from:
- A. 30 centimeters → too small (about the size of a ruler)
- B. 5 meters → too small (about the height of a house wall)
- C. 50 kilometers → way too big (that’s 50,000 meters — like a long highway)
- D. 23 meters → reasonable for a medium-sized Ferris wheel

✔ Answer: D. 23 meters

2) Screw

- A typical screw is small.
- Most screws are a few centimeters long.
- Let’s check:
- A. 20 centimeters → too long (like a ruler)
- B. 25 centimeters → even longer
- C. 3 centimeters → possible for a medium screw
- D. 1 meter → way too big

✔ Answer: C. 3 centimeters

3) Can of Beans

- A standard can of beans is about the size of a soda can.
- Height: around 10–15 cm.
- Options:
- A. 120 centimeters → 1.2 meters (like a person)
- B. 2 meters → huge
- C. 2 kilometers → absurd
- D. 10 centimeters → perfect (typical can height)

✔ Answer: D. 10 centimeters

4) Flash Drive

- A flash drive is small, about the size of your thumb.
- Usually 5–10 cm long.
- Options:
- A. 30 centimeters → too long (like a ruler)
- B. 60 centimeters → half a meter — too big
- C. 2 meters → no
- D. 15 centimeters → possible? Maybe a little long, but some are that size.

Wait — let's reconsider: most USB drives are about 5–8 cm, so 15 cm might be on the longer side, but among the choices, D is the only reasonable one.

But wait — look again:

- A. 30 cm → too big
- B. 60 cm → no
- C. 2 meters → no
- D. 15 cm → still long, but maybe acceptable?

Actually, many flash drives are around 10 cm, so 15 cm is plausible, but let's see if there’s a better fit.

Wait — perhaps the image shows a standard-sized flash drive, which is typically 5–7 cm.

But none of the options include 5 cm.

Given the choices, D. 15 centimeters is the closest realistic option.

But let’s double-check: maybe it's a larger model?

Alternatively, could it be A. 30 centimeters? That would be like a pen.

Still, 15 cm is more typical than 30 cm.

Wait — actually, many USB drives are about 10–15 cm, so D. 15 centimeters is acceptable.

✔ Answer: D. 15 centimeters

5) Adult Horse

- An adult horse is about 1.5 to 2 meters tall at the shoulder.
- Some horses can be up to 2 meters tall.
- Options:
- A. 90 centimeters → 0.9 m → too short (a small dog)
- B. 2 meters → perfect
- C. 120 millimeters → 12 cm → tiny
- D. 30 centimeters → very small

✔ Answer: B. 2 meters

6) Recliner

- A recliner chair is about the height of a person sitting.
- Typically, from floor to top of backrest: about 1 meter.
- Options:
- A. 60 centimeters → too short (less than knee height)
- B. 1 meter → good
- C. 120 millimeters → 12 cm → no
- D. 10 millimeters → 1 cm → no

✔ Answer: B. 1 meter

7) 11 Story Building

- Each story is about 3–4 meters high.
- So 11 stories × 3.5 m = ~38.5 meters.
- Options:
- A. 1 meter → no
- B. 3 kilometers → 3,000 meters — too big
- C. 335 centimeters → 3.35 meters → too short (just over 1 story)
- D. 30 meters → close! (about 10 stories)

So 30 meters is a reasonable estimate for an 11-story building.

✔ Answer: D. 30 meters

8) Key

- A standard key is about 5–10 cm long.
- Options:
- A. 5 centimeters → very likely
- B. 2 meters → too big
- C. 15 centimeters → a bit long for a normal key
- D. 150 centimeters → 1.5 meters — no

✔ Answer: A. 5 centimeters

9) Notebook Paper

- Standard notebook paper is about 21–28 cm wide.
- But the image shows height of a sheet.
- A standard sheet of paper is about 28 cm tall (A4 paper).
- Options:
- A. 15 centimeters → too short
- B. 1 meter → 100 cm → too long
- C. 60 centimeters → too long
- D. 25 centimeters → close! (A4 is ~29.7 cm)

So 25 cm is a good approximation.

✔ Answer: D. 25 centimeters

📝 Summary of Reasoning:

- Use real-world knowledge of object sizes.
- Know metric conversions:
- 10 mm = 1 cm
- 100 cm = 1 m
- 1,000 m = 1 km
- Eliminate clearly wrong answers first.
- Choose the most reasonable estimate.
