Let's solve each part of the worksheet step by step. The task is to
measure each object using the ruler shown and
round to the nearest centimeter.
---
a. Pen
- The pen starts at
0 cm and ends just past
13 cm, but before 14 cm.
- Looking closely: it ends at about
13.5 cm.
- Since we round to the
nearest centimeter, we look at the decimal:
- 13.5 rounds up to
14 cm.
✔ Answer: 14 cm
---
b. Pushpin (Tack)
- The pushpin starts at
0 cm and ends between
2 cm and
3 cm.
- It appears to end at about
2.2 cm.
- Rounding to the nearest centimeter:
- 2.2 is closer to
2 than to 3.
✔ Answer: 2 cm

c. Crayon
- The crayon starts at
0 cm and ends just past
6 cm, but not quite at 7 cm.
- It looks like it ends around
6.3 cm.
- Rounding 6.3 →
6 cm (since 0.3 < 0.5).
✔ Answer: 6 cm
---
d. Glue Stick
- The glue stick starts at
0 cm and ends just after
5 cm, around
5.4 cm.
- Rounding 5.4 →
5 cm (since 0.4 < 0.5).
✔ Answer: 5 cm
---
✔ Final Answers:
- a.
14 cm
- b.
2 cm
- c.
6 cm
- d.
5 cm

Tip: Always align the object with the 0 mark, and look at where the end falls. If it's halfway or more, round up; otherwise, round down.
