Fish Gate Counting Math Game

Allow the fish through the fish gate such that the number of fish on each side matches the required number.  A level is complete once the correct number of fish are on each side of the gate.

Each side has a large number showing in the background which is the required number of fish needed on that side.  Get the required number of fish on each side by sliding the gate up and down to allow and prevent fish from getting through to the other side. To move the gate with a mouse just move the mouse up and down.  On touch devices touch the screen.
