3rd Grade Understanding Fractions Worksheet (PDF)
This fractions practice worksheet for 3rd Grade covers understanding fractions (Common Core 3.NF.A.1, 3.NF.A.2), with a free PDF to print.
These 20 problems practice naming fractions of a whole, unit fractions, and fractions on a number line (Common Core 3.NF.A.1 and 3.NF.A.2). You will shade models, read tick marks, and mark points.
The first problems are quick checks. The last six are word problems with ribbons, gardens, and trails. Work from the top and draw when it helps.

Key facts behind this fractions practice worksheet
- A fraction describes equal parts of one whole.
- The denominator (bottom) counts the equal parts in the whole; the numerator (top) counts the parts named.
- A unit fraction has numerator 1 and shows one equal part, such as 1/8.
- The fraction a/b is a copies of the unit fraction 1/b.
- On a number line from 0 to 1, a/b is the point reached after a hops of length 1/b.
