Divide a unit fraction

💡 How it plays and why it helps

Half of a third of a pizza is a sixth of the whole, and that surprises many children. Divide a unit fraction asks it in numbers: one half to one sixth divided by 2, 3, 4 or 5, with three fractions to choose from. The list is short, so the same card often returns within a round of ten. Your child taps an answer in this Grade 5 game, and each one is checked.

Dividing a fraction by a whole number cuts each piece into smaller equal pieces. The hint gives the check that matters: the answer must be smaller than the fraction you started with. One fourth divided by 3 is one twelfth, because three twelfths make a fourth. The bottom number grows; the pieces shrink.

Bigger answers betray multiplication. For 1/4 ÷ 3, the choice 3/4 sits beside 1/12, and 1/7 adds the numbers. Ask, "Should sharing a piece give you more or less?" Three fourths is more, so it cannot be right. Then say, "You checked that the answer got smaller."
