Fractions of Mine
fractions · adding fractions with denominators 10 and 100
To add fractions with denominators of 10 and 100 [4.NF.C.5].
Fractions of Mine is a Grade 4 card game for adding fractions with denominators of 10 and 100. On each turn, a player draws a problem card, records the sum, and keeps the card only if the answer is correct. The repeated tenths-and-hundredths structure helps students use equivalence between these denominators instead of treating each problem as a completely new case.
Use it for partner or small-group review when students need practice rewriting tenths as hundredths before adding. Opponents check each answer, so equivalence and accuracy can be discussed immediately. Create a free Find a Math Game account to generate lesson support for Fractions of Mine.
