Toothpick Prediction Game
Dear Math Cats,
I have an idea for a new math craft (or is it a math game? I can't decide)
What you will need:
- A pack of small toothpicks
What to do:
Glue four toothpicks together so that they form a square. Multiply the number of sides a cube has (6) by the number of toothpicks it takes to make one side (4) to see how many toothpicks are needed to make a cube. The answer is 24, so make a pile of 24 toothpicks. Do this with other 3-D shapes (Like pyramids) until you have several piles of toothpicks. Then have the other person come into the room.
Ask the person:
"Can you tell me which of these piles of toothpicks would make a cube?" Let the person count the toothpicks in each pile, but don't let them glue the toothpicks together or hold them together to see what shape they form.
Try this with the other shapes you made, too. Then let the other person make piles of toothpicks and you guess.
I hope you like my idea.
Sincerely,
____________________
