Let's solve the "How Long?" worksheet step by step. The task is to measure each object using the ruler provided and record the length in centimeters (cm). Each ruler is marked from 0 to 15 cm, with small tick marks representing millimeters.
We'll go through each object one by one:
---
1. Pencil
- The pencil starts at
0 cm.
- The tip of the pencil ends at
6.5 cm (just past the 6 mark, halfway between 6 and 7).
-
✔ Measurement: 6.5 cm
---
2. Matchstick
- The matchstick starts at
0 cm.
- The red tip ends at
5.0 cm (exactly on the 5 mark).
-
✔ Measurement: 5.0 cm
---
3. Truck
- The truck starts at
0 cm.
- The back of the truck ends at
8.0 cm (exactly on the 8 mark).
-
✔ Measurement: 8.0 cm
---
4. Spoon
- The spoon starts at
0 cm.
- The end of the spoon bowl ends at
9.5 cm (halfway between 9 and 10).
-
✔ Measurement: 9.5 cm
---
5. Knife
- The knife starts at
0 cm.
- The tip of the blade ends at
7.0 cm (exactly on the 7 mark).
-
✔ Measurement: 7.0 cm
---
✔ Final Answers:
1.
Pencil: 6.5 cm
2.
Matchstick: 5.0 cm
3.
Truck: 8.0 cm
4.
Spoon: 9.5 cm
5.
Knife: 7.0 cm
You would write these numbers in the boxes next to each object.

Tip: Always make sure the object starts at the
0 mark on the ruler for accurate measurement. Read the measurement at the end of the object, and use the smaller ticks for precision (each small tick = 1 mm).
