This lesson focuses on the characteristics of a circle including similarity, radius, circumference, and Pi. It provides formulas to determine the area of a circle, calculating Pi, and learning exercises throughout.

Working as a team, students discover that the value of pi (3.1415926) is a constant and applies to all different sized circles. The team builds a basic robot and programs it to travel in a circular motion. A marker attached to the robot...

Find a quick, concise explanation of Pi. Examples are given and clearly explained.

Rather than dividing a circle into some number of segments (like 360 degrees), mathematicians often prefer to measure angles using the circumference of a unit circle - a circle with radius 1. This way of measuring angles is called...

The circle is one of four different shapes which can be created using "slices" through a cone, a 3-dimensional solid that has a circular base joined to a single point (called the vertex) by a curved side. If you tilt a cone, you get an...

At its core, the LEGO MINDSTORMS product provides a programmable microprocessor. Students use the EV3 processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying...

Santa Maria del Pi (Barcelona)

This is a great place for lesson information on the concept of pi. Three other tabs are available besides the-What Is It? tab. They are: Tips and Tricks, When Students Ask, and Lesson Ideas. Each tab has just the right amount of...

Experiment with a simulation to get an approximation of Pi by dropping a needle on a lined sheet of paper.

A lesson that introduces students to the International Phonetic Alphabet. Students learn the symbols for vowels used in Italian and apply them to an Italian song. The lesson culminates with students creating a podcast.

Students practice their multiplication skills using robots with wheels built from LEGO MINDSTORMS NXT kits. They brainstorm distance travelled by the robots without physically measuring distance and then apply their math skills to...

This site provides detailed information on the Chinese invention of block printing. Includes an image of the carved wood that was used in early Chinese printing.
