Curated OER
Basic Geometric Constructions
Learners observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...

Vectors Via the Calculator
Eighth graders resolve vector problems without the knowledge of math. In this vectors lesson students with poor math skills get a chance of passing the course.
Curated OER
Parallax
Students discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."
Curated OER
Graph Both Crusts
Fourth graders calculate the angles and construct a pie graph of the percentages of the elements in the continental and oceanic crusts. Then they analyze the results. They can be assigned the task of researching the percentages.
