Groups of 3 students used Educreations to solve a logic problem.
A farmer is on 1 side of a river with a goat, wolf, and cabbage and he needs to get all 3 to the other side. He has a boat to use that will hold him and 1 other thing. He can't leave the goat and cabbage alone on 1 side of the river because the goat will eat the cabbage. He can't leave the goat and wolf alone on 1 side of the river because the wolf will eat the goat. How can he get them all across?
Students drew and explained the steps, tried, erased, and tried again. It was great to watch. Unfortunately, we did this during the Educreations "bug" time so the videos aren't able to play. Of my 8 groups 2 were able to solve with no hints and all were able to solve with the hint that the farmer takes 1 thing back across the river with him 1 time.
