Crumb's Same-Amount Bakery — Equivalent Fractions (Grade 3)
A free interactive Grade 3 fractions activity: Crumb the mouse shows a piece cut one way, then three pieces cut into more or fewer slices. Tap the one that is the SAME amount — the equivalent fraction (like 1/2 and 3/6). Shaded bars plus the fraction numbers let children see that different fractions can name the same amount.

About this activity
Crumb the mouse shows a piece cut one way, then three more cut into more or fewer slices, and the child taps the one that is the same amount — the equivalent fraction — for pairs like 1/2 and 3/6, or 3/4 and 6/8. Each fraction appears as a shaded bar beside its numbers, so the size is visible. It's a free, interactive Grade 3 fractions activity that plays in the browser on any device, with no sign-up.
The big idea is that different fractions can name the very same amount. The reference fraction (such as 1/2, 1/3, 2/3, or 3/4) sits beside three candidates that are cut into different numbers of slices, and only one shades the same length of bar. The other choices are close but wrong — for 1/2 the decoys might be 2/6 or 5/6 — so the child compares the shaded amounts, not just the numbers, and learns to look past 'different numbers' to 'same size.'
It is aligned to Common Core 3.NF.A.3 — recognizing and generating simple equivalent fractions and explaining why they are equal. No timer, no score — just calm, playful practice.
What's inside this activity
- Designed for Grade 3 learners (ages about 8–9)
- Common Core strand: Number & Operations—Fractions
- Aligned to Common Core standard 3.NF.A.3
How to play
Look at Crumb's reference piece and how much of the bar it shades.
Compare the three candidates — each cut into a different number of slices.
Tap the one that shades the same amount; try again freely, with no timer and no score.
What your child practices
- Recognizing that two fractions with different numbers can be the same amount
- Comparing shaded bars to judge which fraction matches the reference
- Connecting the picture of a fraction to its numerator and denominator
- Spotting close-but-wrong fractions that shade more or less of the bar
Learning goals
Recognize simple equivalent fractions like 1/2 = 3/6 — the focus of Common Core 3.NF.A.3
Understand that equivalence is about equal amounts, not matching numbers
Build the equivalence sense needed for comparing and adding fractions later
