2nd grade unit fractions & parts of a whole worksheets
Fraction worksheets for second grade draw a bar cut into equal parts with some shaded, and your child writes the fraction: unit fractions like 1/4 and simple fractions like 3/4, in halves, thirds, and fourths. The top counts the shading, the bottom counts the parts.

The kind of problems you'll get
Write the shaded fraction using the number of equal parts shown. Each shape is one whole.
-
A whole is split into four equal parts. What is one part called?
Answer: One fourth, or one quarter.
Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.
Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.
What's on a 2nd grade sheet

Every version prints on US Letter or A4, with its answer key after the problems.
How to teach this
Fold a strip of paper into four equal parts and shade one ("this is one fourth"), then shade another and ask what changed. Only the top number moves. If shading is hard to count on the sheet, have your child tick each shaded part with a pencil first.
Watch for: Kids count the shaded parts for both numbers. The bottom counts all the equal parts, the top counts only the shaded ones. Kids assume a bigger bottom number means a bigger fraction. It is the other way round: more equal parts means smaller parts, so 1/8 is smaller than 1/2.
Common questions about 2nd grade unit fractions & parts of a whole
- What is a unit fraction?
- A fraction with 1 on top, exactly one of the equal parts. It's the building block: 3/4 is just three of the 1/4 pieces, and these sheets build that idea from the picture up.
- Does my child need to draw or shade anything?
- No. Every bar is printed and shaded already. The work is reading the picture and writing the fraction on the line.
