With our world in so much turmoil and refugees trying to survive hardships by traveling away from their homes, the story of Little Amal is powerful and touching. Of course there is lots of math in creating an 11 foot tall puppet that can be controlled by 3 people and show fear, surprise, wonder, and generally the humanity of refugees. Bring the story of Amal to your classroom with this timely art.

This is the season for increased cyclonic activity around the globe. How are hurricanes, typhoons, and cyclones related?
There is a measurement called the Accumulated Cyclone Energy (ACE). How is it measured? Are storms becoming more intense? Did you know there is a formula for measuring the strength of storms and storm seasons? Let's see if this formula for measuring the intensity of storms makes any sense?

Wow! Check out this deal at Macy's. For $25 I can join Macy's Star Rewards program. I get 10% back in rewards for every dollar I spend. Its pretty cool that Macy's gives part of that $25 to charity. Should you do it? It seems like free money (or clothes) just for shopping at Macy's. Factoring in the $25 enrollment fee, how much do you need to spend at Macy's to come out ahead? For what total shopping dollar amounts is this a bad deal for the consumer? What dollar amount must you spend to at least break even? Can you write a rule that gives the dollars earned at Macy's after the $25 registration fee for any dollar amount of purchases?
