Bedtime Math Book


Bedtime Math, featured in these pages two Aprils ago, has its first book coming out this Tuesday, 25 June.

Available from Macmillan Publishers in hardcover format (96 pages) or for Kindle, Bedtime Math: A Fun Excuse to Stay Up Late gives families more than a hundred "mischief-making" math riddles on everything from jalapeños and submarines to roller coasters and flamingos, enlivened with full-color illustrations throughout.

As with the bedtimemath.org website, Bedtime Math's all new math problems come in three different levels of challenge: big kids, little kids, and "wee ones."

Watch a trailer for the book:

"I'm developing some math educational software aimed at high school kids in algebra, and I'm wondering what the most important platforms are: Windows, Mac, IOS (iPad, iPhone), or Android. In the world at large there are an awful lot of Windows machines, but if you look specifically at high school students, there may be a greater number of iPads and Android tablets.

As mentioned here in March, Desmos' sliders and other intuitive features have inspired three teachers to post two new plots every weekday and ask, "Can you create the following graph?" The Daily Desmos has since grown to include dozens more challenges for your plotting puzzlement:

Now taking place: math education conversation of the day

"It was proof-based Euclidean geometry that turned me onto mathematics and is part of reason that I so vociferously condemn its death in US schools in our lifetime. The teacher wasn't great but he guided us well and the material spoke for itself."

Teacher Prep Review


Earlier this week, the National Council on Teacher Quality (NCTQ) released a study of 2,420 teacher preparation programs — undergraduate and graduate; elementary, secondary and special education — at 1,130 U.S. institutions of higher education.

In addition to ratings schools of education, NCTQ offers materials, some contributed by teacher preparation programs, specifically for
