Any fraction can be built by adding the same small piece again and again. This 3rd grade writing fractions as unit fraction sums worksheet has six questions, numbered 1 to 6, and each one asks the same thing. Which expression shows the fraction as a sum of unit fractions? The fractions are 4/5, 5/8, 2/4, 3/6, 7/11 and 5/12. Under each question, there are three sums with a tick box beside each one. Only one sum uses pieces with a numerator of 1, and it has as many pieces as the top number says. A boy jumps for joy at the top, and two girls in headscarves hold hands at the bottom. Page two ticks the right sum for every item and draws a model for item 1.
