Pumpkin pie fractions game: a 25-minute Thanksgiving activity, 3–5

1. Each student draws two large circles, the "pies", and cuts each into eighths with four lines through the center. Show how on the board: halves first, then quarters, then eighths.
2. Write the roll key on the board: 1 = 1/8, 2 = 2/8, 3 = 1/4, 4 = 3/8, 5 = 1/2, 6 = choose any fraction on the key.
3. Partners take turns rolling and shading. The rule: say the fraction and, when you can, an equivalent one. "I rolled a 3. One quarter is the same as two eighths, so I shade two slices."
4. Pies must be filled exactly. If a roll is too big for the space left, the player can split it across both pies ("one half is two eighths here and two eighths there") or pass.
5. The first player to fill both pies wins. The winner walks their partner through each piece they shaded.
6. Close with a class question: "Which roll was most useful at the end, and why?" Students usually discover that small fractions help most when a pie is almost full.

Extension: students write the fractions on one pie as an addition sentence that equals one whole, for example 1/4 + 3/8 + 1/8 + 2/8 = 1. Fourth and fifth graders rewrite it with a common denominator and check that the numerators add to 8.

Differentiation: for 3rd graders new to fractions, cut the pies into quarters and use a key with only 1/4, 2/4 and 1/2. For advanced students, cut the pies into twelfths and add 1/3 and 1/6 to the key. For English learners, label a drawn pie with "half", "quarter" and "eighth" and leave it on the board. For students with motor needs, pre-draw the pies on a whiteboard so they only shade, or give them paper plate slices to place by hand.

Quick check: draw a pie with 3/8 shaded and ask: "How much more fills it? Name it two ways." (5/8, or 1/2 + 1/8.)
