Part 1: A little Math story brought to you by…..

Ms. Evans

The Magic Toy Machine

One day, a long time ago, in a far away land lived a crazy scientist. Everyone thought he was a little strange, but he did have a lot of experiments go wrong……

He wanted to do something right and help out a local toy store. See, the store couldn’t keep up with the demands of the new life like teddy bear that attacked predators of young children. So, he decided to build a machine that would keep up with this awesome new invention…..

After months of slaying away, his machine (the kookalamoo) was ready! His machine started with 1 teddy bear, put it through the machine and an hour later it came out as two. He then put those two in and in hour later each of those made two more, and so on and so on…..

Group Investigation

The teddy bears kept MULTIPLYING fast. How many

teddy bears did he have after 5 hours?
