When two fractions have the same bottom number, adding them is almost as easy as adding whole numbers. This 3rd grade adding and subtracting like fractions worksheet has eight items, numbered 1 to 8, in two columns on grid paper. Items 1, 3 and 5 are sums, such as 2/7 + 3/7, while the other five are differences, such as 15/10 – 7/10. Every pair in an item shares the same denominator, so your child only works with the top numbers. The instruction also asks them to simplify each answer. Two scouts sit by a campfire at the top, and a girl with binoculars waits at the bottom. Page two writes out every step and puts the final answer in a pink box.
