A clean and safe environment is important for everyone and everything, including frogs like those you see in the game below! So if you like frogs and want to help study and protect them, please visit and .
But first, tease your brain with a game!
Print out the puzzle page. Cut out the six frogs, and put each frog on its own rock. Put the three green frogs on the rocks on the left and the three brown frogs on the rocks on the right. There must be an empty rock in the middle Like this:
green frog - green frog - green frog - empty rock - brown frog - brown frog - brown frog
See how quickly you can switch the frogs to the opposite side of the pond.
Green frogs can only hop to the right. Brown frogs can only hop to the left. Frogs can only jump onto an empty rock. A frog can jump over one frog to an empty rock—but only over one.
Frogs cannot jump back, only forward. It’s easy to tell which way they can go—they face the way they want to jump.
If you get stuck and your frogs can’t jump anywhere, move them back to where they started and try again.
When all the frogs have reached the other side of the pond, you win!
