The Magic in Wondering about a Million, Billion, and Trillion

In the book, Marvelossissimo the Mathematical Magician leads the way through a sequence of "If, then" statements about three quantities: One million (1,000,000), One billion (1,000,000,000) and One trillion (1,000,000,000,000).  The book offers answers to these questions: How high would one million/one billion/one trillion kids reach if they climbed on each other's shoulders? How big a goldfish bowl would you need to hold one million/one billion/one trillion goldfish? How long would it take to count to one million/one billion/one trillion? How many pages would one million/one billion/one trillion stars fill?

I first learned about this book while exploring McElligott's website... Continue Reading →

Math Cookbook Magic

The six recipes in this cookbook involve fractions, tessellations, circles, π, fibonacci numbers, geometric shapes, and probability. My children counted and sorted when making the Probability Trail mix. They measured and divided when calculating the ratio of the circumference to the diameter in Variable Pizza Pi and they added and counted while making their Fibonacci snack sticks. Finally, equivalent fractions were investigated a bit with Fraction chips.

Teaching Time without Telling with Big Mama Cat

I needed a way to help him makes sense of telling time without subjecting him to a step-to-step lecture one the ins-and-outs of analog clocks. After researching which time-focused picture books elementary teachers use in their classrooms, I headed to the library. This post is about our favorite telling time book and some clock cards I created to talk time with Liam.
