Fraction PON: Add & Explore

Explore fraction addition with your own hands. What happens when you join 1/2 and 1/4? How small is half of a half? Fraction PON lets children explore those questions by joining and halving colorful circles and squares. Move the pieces, compare their sizes, and connect what you see with the numbers. A hands-on starting point for children meeting fractions, with room to experiment at their own pace. SEE FRACTIONS ADD UP Join 1/2 and 1/4 to make 3/4. The equation changes from 1/2 + 1/4 to 2/4 + 1/4 = 3/4. See how using equal-sized parts gives the fractions a common denominator. CUT IT. JOIN IT. CHECK IT. Cut a whole into halves, then cut a half again. Watch the shapes and numbers change together. Join the pieces back up to explore how the same amount can be split into different parts. TRY YOUR OWN WAY Which pieces will make the target? Should you join first or cut first? Undo a move or restart the puzzle to try another idea. There is no time limit. 110 PUZZLES, STARTING WITH 18 EASY STEPS Begin by joining two halves. Move on to different denominators, extra pieces to choose between, and multiple targets to make at once. Mixed numbers such as 2 and 1/3 appear too. Choose any puzzle from the list and replay completed puzzles. Ready for another challenge?
