Here's a method to always win at the game, I Spy, and at the same time secretly learn about something called exponential decay. A mathematical concept that applies to everything from the cooling of a cup of coffee to radioactivity decay.

Here's a solution to the matchstick game that asks you to create a 4 unit continuous area using exactly 12 matches, a bit tricky if you don't know a little Pythagoras.

Math facts aren't that much fun to learn but they're necessary to develop fluency. Here's a fun way to gamify the Multiplication Table. My daughter and I played this and she loved making the cute faces. She brought it to school and showed her teacher who asked me for the worksheet. My kid gave a presentation to her class about how to play and now it's an activity they have in rotation. I attached the worksheet as a PDF you can download and print out

I wanted to demonstrate how anyone can use a little science to drive change. This is a simple science experiment that started with an observation - there's always a little water left in a water bottle. The result is if 1/4 of all discarded water bottles have a small amount of water left in them and the cap is not taken off, then we are losing an Olympic-sized swimming pool every 12 hours. That's the amount of water needed for 8 million people lost every year. Not good, but people don't know. See for yourself and spread the word.

With the recent launch of Artemis II, the first manned mission to the moon in 53 years, I wanted to take the opportunity to talk about the actual scale of space. We have all seen so many images of the solar system that are scaled for presentation that I'm afraid we've lost any sense of an accurate model for how immense space actually is. To scale it down to a manageable size, if the Earth was the size of a basketball the moon would be the size of a tennis ball. How far apart should they be in this model? The answer might surprise you!
