Let's solve the problem step by step.
The worksheet asks:
"How many cm does the arrow show?"
Each row has a ruler marked from 0 to 15 cm, with small tick marks between each whole number. Since the title says "HALVES," we know that the ruler is divided into
halves of a centimeter, meaning each small tick represents
0.5 cm (or half a centimeter).
We need to read where the blue arrow points on each ruler and write the measurement in centimeters.

Step-by-step analysis:
####
1st Ruler:
- Arrow points just
after 1, at the
first small tick after 1.
- That’s
1.5 cm.
✔ Answer:
1.5 cm
####
2nd Ruler:
- Arrow points
at the 3 mark.
- The arrow is exactly on the
3 cm line.
✔ Answer:
3 cm
####
3rd Ruler:
- Arrow points
between 2 and 3, but at the
first tick after 2.
- That’s
2.5 cm.
✔ Answer:
2.5 cm
####
4th Ruler:
- Arrow points
between 5 and 6, at the
first tick after 5.
- That’s
5.5 cm.
✔ Answer:
5.5 cm
####
5th Ruler:
- Arrow points
at the 11 mark.
- Exactly on the
11 cm line.
✔ Answer:
11 cm
####
6th Ruler:
- Arrow points
between 4 and 5, at the
first tick after 4.
- That’s
4.5 cm.
✔ Answer:
4.5 cm

Explanation:
- The rulers are marked in
half-centimeter increments.
- Each long line = 1 cm
- Each short line between them = 0.5 cm
- So, for example, halfway between 1 and 2 is 1.5 cm, etc.
This helps students practice reading measurements to the nearest
half centimeter.
