The goal of this site is to demonstrate the beauty of mathematics. The creator also wants to show the wonder and intellectual playfulness of math. Included on the site are many videos and essays exploring higher level mathematics. Titles include "How to Think Like a School Math Genius", "A Cute Finger Trick for Trigonometry", and "What is Zero to the Zeroth Power?". Most video titles are approximately 10 minutes in length. Also available on the site are two free PDF downloads: Guide to Everything Quadratic and Guide to Fractions. Be aware: parts of this site require some navigation (a few clicks) to get to your destination. But the "clicks" are well worth the time. At the time of this review, the link to "Curriculum Tidbits" was not active, but the Think Curriculum tab works. Although the author's books are available for sale on the site, there is plenty of free material available making the site worth exploring.

This site offers several interesting interactives for practicing math concepts at the elementary level. Many games go beyond the standard rote-type practice and involve critical thinking skills. For example, Beads on a String asks you to create a bead necklace using a pattern, but then asks that bead number 102 be blue adding difficulty to the challenge. Other activities involve estimation, money, logic, and symmetry. Activities can be sorted by age (5-12). Parts of this site appear in Dutch and you may have to simply hit the "translate" button to see the instruction in English.
