  • Prealgebra Schedule Update

  • Gap Year Math

    Hello mathematicians, puzzlers, and other curious people! Taking some time off from classes is an idea people are considering more seriously right now than they usually would. If you\’re thinking about something along these lines, but you\’re not sure how you\’re going to keep from losing the math skills you\’ve worked hard for years to…

  • Upcoming Prealgebra Class

    Hello mathematicians, puzzlers, and other curious people! Do you need a math class for a junior high student who\’s home for the year? Beginning Mathematical Reasoning is based on the first chapter of Jousting Armadillos & Other Equations, a prealgebra book originally written for 6th graders. Since it\’s prealgebra, anyone up to 8th grade can…

  • Multiplication Methods Commentary

    Hello mathematicians, puzzlers, and other curious people! The other day I saw something in a (mostly math teachers and adjacent) Facebook group that\’s too good to not repost. Without further comment, since it speaks for itself: #whenIstoplearningnewthingspleaseplantatreewhereyouburyme

  • Verification

    Hello mathematicians, puzzlers, and other curious people! Just a quick note today about a mathematical statement I found on Twitter: Really there are two statements here: the length of a day in milliseconds, and the interesting factored form of that number (not a factorial, but reminiscent of one). Let\’s check both. Post your ideas in…
