World of Measurement
"World of Measurement is a site designed for specifically for elementary students, so it focuses on the five most common measurements: length, mass, temperature, time and volume. It does not include any online calculators, but rather features explanations (what is mass?), tables of conversion and exercises to test your knowledge. Use the Site Map (link at the bottom of the page) to see all the activities and quizzes."

World Book: Counting the Days
"World Book editors have created a site for elementary and middle-school students that answers basic questions about the invention of the calendar. What I found most fascinating was the brief discussion of two proposed calendars that would simplify our timekeeping. The fixed (or thirteen month) calendar inserts the month of Sol after June. Each month is exactly four weeks long and an extra day (called a year day) is added at the end of the year. The second option is the world calendar which has twelve months of thirty or thirty-one days, and also has a year day at the end."

What is a Tessellation?
"This Math Forum page is a great introduction to tessellations for those who know some geometry. It defines regular tessellations (those made up of polygons whose sides are of equal length), and shows how the interior angles of a regular tessellation must be an exact divisor of 360 degrees. Included are links to a lesson plan (for teachers and homeschoolers) and additional activity pages for students. You can experiment with shapes from this (or any other site) by copying them (use a right mouse click) to a paint program. Within the paint program, you can rotate and paste the shapes into tessellations of your own."
