Dear Math Moms & Dads:


Does your child have a math question to ask James?

Each week he selects a question and answers it in a letter!

See the notes below for details.

James likes deep-thinking, "I wonder" questions and your students surely have many of those: "Why can't you divide by zero and what could go wrong if you do?" and "Why are there 360 degrees in a circle? Where did that number come from?" and "Would Martians do math the same way we do?" for example, would be questions he would take on! (So no textbook questions and computation questions. Let's have more fun than those!)

Feel free to submit more than one question.

Let question-asking in math be wild and fun and free!
