In this interactive, use logic to solve riddles involving flea circus high jumps. Then, add two consecutive jumps and place them on a vertical number line. This often requires you to find equivalent fractions with common denominators. Numbers are randomized so that you can answer riddles and place fleas on the number line multiple times. The accompanying classroom activity includes a fraction/decimal concept review and a response sheet to support the online work. This resource is part of the Math at the Core: Middle School Collection.
