This classic puzzle requires all the frogs on the left side of the pond to reach the right side and vice versa. How many moves does it take to solve the puzzle? What if there were more frogs? Click on the frogs in this TI-Nspire document to make them move, the moves are counted automatically. Set the number of frogs on each side and start solving!

About the Lesson
Students solve the original problem with 3 frogs on each side of the pond and record the number of moves. The number of frogs on each side of the pond is then changed and systematically explored to determine a relationship between the number of frogs on each side of the pond and the number of moves required to solve the problem. As an extension the number of frogs on each side of the pond is no longer equal. Students are posed a series of guiding questions to help them understand the algebra.
