A sorting sheet on equal shares. Six partitioned shapes, labeled A to F, get sorted into a Halves column and a Fourths column; the key puts A, D and F with halves and B, C and E with fourths. A short Share Check follows: how many equal parts halves and fourths have, and which parts are smaller. The final tick box carries the idea the standard cares most about.
1.G.3
“Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.”
The sort uses the standard's own share names, and the final question targets its trickiest clause: decomposing into more equal shares creates smaller shares.
Six diagrams of circles and rectangles split into equal parts, each labeled with a letter, like the circle with a vertical line down the middle for Shape A.
A two-column table headed 'Halves (2 equal shares)' and 'Fourths (4 equal shares)'. Students write each letter in the correct column.
Three quick items: a shape cut into halves has ______ equal parts, a shape cut into fourths has ______, and a tick box for which parts are smaller.
Fold first
Fold a paper circle in half, then in half again, before the sort. Students who watched the fold rarely tick halves as the smaller share.
Class vote
Run the sort as a vote, shape by shape, and make students defend each placement with the count of equal parts.
Misconception check
Collect the Share Check section on its own. Anyone who answers that halves are smaller needs the folded-paper demonstration again.
