Description
Thirds are often the first fraction that makes students stop and think, because a third is not simply “half of a half.” This Fractions Thirds Worksheet helps third graders understand what the numbers in a fraction really mean. The bottom number tells how many equal parts make the whole, and the top number tells how many of those parts are counted. When students see one third and two thirds on circles, bars and small sets, they learn that a fraction names equal parts no matter what the whole looks like.
In Part A of this Fractions Thirds Worksheet, students study six models: fraction circles, fraction bars and sets of three dots. Each model is split into three equal parts, and some of the parts are shaded. Students write the fraction that names the shaded part on the blank fraction bar beside it. In Part B, the fraction is printed for them, and students shade four blank circles to match. Because the models change from card to card, students must count the parts every time instead of copying a pattern. Use the page for guided practice, a math center, an exit ticket or homework. The answer key on the last page makes checking quick.
What’s Included
- One printable 3rd grade fractions worksheet page with a name and date line
- Part A: six shaded models in thirds to name with a fraction
- Three kinds of models: fraction circles, fraction bars and sets of three
- Part B: four blank circles in thirds to shade to a printed fraction
- A full answer key on the final page
Three Reasons This Helps Kids Learn
- Seeing thirds on circles, bars and sets shows students that a fraction describes equal parts of any whole.
- Moving from reading a model to shading a model builds understanding in both directions.
- Writing the numerator and denominator by hand reinforces what each number in a fraction stands for.
Teachers and parents can extend this practice with everyday objects. Fold a strip of paper into three equal parts and color one or two sections. Share a small snack among three people and name each share as one third. Ask students to draw their own model in thirds on the back of the page and trade with a partner to name the shaded part. For a challenge, ask what fraction names all three parts shaded, and talk about why three thirds make one whole.
