In this interactive, use logic to solve riddles involving a jumping frog contest. Add two consecutive jumps by one frog and place the jumps on the number line, finding equivalent fractions with common denominators to do so. Numbers are randomized so that riddles can be answered and frogs placed on the number line multiple times. The accompanying classroom activity includes a fraction/decimal concept review and two response sheets to support the online work. This resource is part of the Math at the Core: Middle School Collection.
