Exponents III- Squares and Square Roots
Students explore the process of inverse operations to solve square root problems. After exploring the perfect squares and area, students examine methods to find square roots by observing the teacher, taking notes, and listing vocabulary...

Sir Cumference and the Dragon Pi
Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and then consider...

The Circumference and Diameter of a Circle
Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.

Fractions and Halves
Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

Line Of Best Fit: Feet & Forearms
High schoolers actively find the line of best fit. They gather their own data and then use a calculator to find the line of best fit, as well as the equation. They see how to use the TI 81 calculator in order to find the line of best fit.
Curated OER
Linear Progression
Students use graphing calculators to graph lines and create tables of values. They perform an experiment using M&M's and slinkys, then create their tables based on their results.

Composting
Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.

Squares and Square Roots II
Students evaluate squares and square roots. Through practice, they discover the inverse relationship between squares and square roots. Students take notes, solve square root and square root problems, and classify numbers as rational or...
