|Lessons not in a Unit|
| ||Circumference of the Earth
||This lesson focuses on using the estimation of the circumference of the
earth to reinforce basic geometric properties of circles and parallel lines.
The lesson continues with using Eratosthenes method to estimate the
circumference of the earth.
| ||Introduction to Negative Numbers
||This lesson introduces the student to negative numbers using the
concepts of magnitude and direction in both visual and kinesthetic
| ||Adding And Subtracting Negative Numbers
||This lesson helps the student to understand the meaning of adding
and subtracting positive and negative numbers.
