Hexagoning the Circle
Students explore similarity to see that the area of a circle should be a constant times the square of its radius. Students create a hexagon. Students share their designs with the class.
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.

Square Circles
Students analyze and demonstrate how a circle can be measured in square units and examine how diameter, circumference and radius are related.
Curated OER
The Derivation of (Pi)
Seventh graders groups measure the diameter and circumference of each of the circular objects in the room. They record their results on their student worksheets and access a computer spreadsheet program to compile their results.
Curated OER
Pythagorean Theorem Investigation
Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.
