Same Size, Different Shape — Equal Shares Can Look Different | Grade 2 Geometry

About this activity

An example shape already split into equal parts appears, and the child taps another shape split into the same number of equal parts — even when the pieces are shaped differently, like a square cut corner-to-corner and a square cut straight down the middle that both show two equal halves. It's a free, interactive Grade 2 geometry activity that plays right in the browser with no sign-up.

The big idea is that equal shares of the same whole do not have to look alike. The other choices show the shape split into unequal parts, split into the wrong number of parts, or not split at all, so the child has to focus on the count of equal pieces rather than on the picture matching exactly. The child recognizes the matching partition; the child does not cut the shapes.

It is aligned to Common Core 2.G.A.3 — recognizing that equal shares of identical wholes need not have the same shape, and naming shares as halves, thirds, and fourths. No timer, no score — just calm, playful practice.

What's inside this activity

• Designed for Grade 2 learners (ages about 7–8)
• Common Core strand: Geometry
• Aligned to Common Core standard 2.G.A.3

How to play

Look at the example shape and see how many equal parts it is split into.

Tap the other shape split into the same number of equal parts, even if the pieces look different, then press Check.

Try again any time; there is no timer and no score.

What your child practices

• Recognize that equal shares of one shape can look different and still be equal
• Match by the number of equal parts, not by pictures that look identical
• Tell equal parts from unequal parts, and the right number from the wrong number
• Use the words halves, thirds, and fourths for equal shares

Learning goals

Recognize shapes split into two, three, or four equal shares — the focus of Common Core 2.G.A.3

Understand that equal shares can have different shapes as long as the parts are the same size

Strengthen the fair-share thinking that names and compares fractions later
