In this short guide you will be able to preview the segment. You’ll also get some great ideas for in-class activities after watching the video with your students.
Here is a creative and fun in-class activity for before/after watching the video…
The following riddle,
The Wolf, the Goat and the Cabbage, is similar to the Crossing the Bridge problem that is in the Video. Both are based on the same concept of how to move things in the correct order. You can present this riddle before or after the Crossing the Bridge video.
The Wolf, the Goat and the Cabbage
Once upon a time a farmer went to a market and purchased a wolf, a goat, and a cabbage. On his way home, the farmer came to the bank of a river and rented a boat. The boat could carry only the farmer and a single purchase: the wolf, the goat, or the cabbage.
Be aware that if left unattended together, the wolf would eat the goat, or the goat would eat the cabbage. The farmer’s challenge was to carry himself and his purchases to the far bank of the river with each purchase intact.
How did he do it?
The first thing the farmer has to do is to take the goat with him to the other side, since the wolf and the cabbage can stay alone together.
Then the farmer must go back so he can get the next passenger.
He can take either the wolf or the cabbage. Let’s say he takes the wolf with him.
When he gets to the far side, he can’t leave the goat and the wolf together, and here is the solution: he leaves the wolf there and takes the goat back with him.
Now, he can leave the goat and take the cabbage with him to the far side.
This time the farmer returns alone!
Then he takes the goat and together they cross to the other side.
That’s 7 crossings in total but the farmer got them all across the river safe and happy for ever after!
