Grade 3 math worksheet where students practice identifying fractions by counting the shaded sections of rectangular bars.

Let’s go through each problem one by one. Each rectangle is divided into equal parts, and some of those parts are shaded gray. The fraction is:

> number of shaded parts over total number of parts

We’ll write each as a fraction like this:
shaded / total

---

1. 3 shaded out of 5 → 3/5
2. 1 shaded out of 3 → 1/3
3. 2 shaded out of 8 → 2/8 (can simplify to 1/4, but we’ll leave as is unless told to simplify)
4. 6 shaded out of 7 → 6/7
5. 4 shaded out of 5 → 4/5
6. 1 shaded out of 2 → 1/2
7. 3 shaded out of 7 → 3/7
8. 2 shaded out of 3 → 2/3
9. 2 shaded out of 4 → 2/4
10. 1 shaded out of 3 → 1/3
11. 4 shaded out of 8 → 4/8
12. 3 shaded out of 4 → 3/4
13. 5 shaded out of 8 → 5/8
14. 5 shaded out of 6 → 5/6
15. 1 shaded out of 3 → 1/3
16. 4 shaded out of 5 → 4/5
17. 2 shaded out of 4 → 2/4
18. 4 shaded out of 6 → 4/6
19. 2 shaded out of 3 → 2/3
20. 3 shaded out of 7 → 3/7
