Once again, I am adding to my Free (Mostly) Math Resources page. Here are a handful of helpful websites for teaching math…
Math History Tidbits: Agnesi, Euler, and China
I’ve fallen behind on my project of transcribing my Alexandria Jones stories. Finally, here are a few more tidbits from math history, along with links to relevant Internet sites and a few math puzzles for your students to try.

The last couple of weeks, in Math Club, we’ve been learning to count. My new set of MathCounts students have never heard of combinatorics, so we started at the very beginning:

- Counting and Probability by Jason Batterson

I love quotations, don’t you? Everything I might possibly want to say, someone else has already said it better than I ever could. Now I’ve put together all of my blackboard quotes from the homeschool co-op classes, as well as a few longer quotations I used in past blog posts, and archived them in one convenient place.
I hope you have as much fun reading the quotes as I have had collecting them.
Writing to Learn Math II

In addition to all the funny Google searches, I get plenty of normal inquiries about math topics. People come here looking for help with fractions, word problems, and math club activities — no surprise, those — but I would never have predicted the popularity of the search topic “writing in math class.”
Last year, I compiled a variety of math journal resources, but I’ve found many more since then, especially for older (high school and college) students. So if you’re looking for new ways to get your math students writing…

Browsing the Internet, I came across a slideshow called 101 Free Learning Tools, which explores “the idea that there is at least one excellent free learning tool (or site) for every learning problem, need or issue.”

School is in session, which means I am once again searching out pithy, inspirational quotations for my chalkboard. Some recent tidbits…
The more I work and practice, the luckier I seem to get.

Quoted in Precalculus Mathematics in a Nutshell
A Mathematician for President
In 1876, a politician made mathematical history. James Abram Garfield, the honorable Congressman from Ohio, published a brand new proof of the Pythagorean Theorem in The New England Journal of Education. He concluded, “We think it something on which the members of both houses can unite without distinction of party.”
