Bedtime Math Problem | A new math problem every night.
A hat tip to Ken B. and Mary W. for reminding us that today is Pi Day! That’s because today is 3/14, a nice representation of our favorite magical number, 3.14. Pi (π) is the ratio between the distance around a circle and the distance across it: the distance around the edge will be the width times 3.14159265… When you roll a ball or a wheel, it’s amazing how far it goes on one roll, relative to the little circle you started with. For today’s BMPs, you can round off π to 3 to simplify the math (and for those who don’t multiply yet, it’s a great way to learn the concept: have them add the number to itself, then add it on one more time). If your child wants to use 3.14 instead, go for it! Wee ones (counting on fingers) : If at dinner a ladybug takes 2 minutes to walk across the middle of your plate, how long will she take to walk once around the edge?
Math is about so much more than computation. Mathalicious supports textbooks by creating opportunities for deep classroom conversations around topics that kids care about. I’ve never seen my kids so excited about a lesson before.

Hunger Games is the latest popular movie to make a big weekend splash. Can you tell from its opening weekend how the movie will do in the long run? This activity can be done for any new movie on the scene. We’ve left blank spaces in our chart for students to add their favorites and we’ve told them where to find the data online. Peyton Manning and Albert Pujols signed big contracts during the winter of 2011-2012, paying each of them millions.
