Radian Measure
In this Algebra II/Pre-calculus instructional activity, students explore radian measure of an angle and convert between degree and radian measure. The seven page instructional activity contains explanation, examples, and nineteen...
Curated OER
Radian Measure
Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.

Finding Areas of Triangles, Rectangles, and Circles
Students find the areas of geometric shapes. In this geometry lesson plan students find and measure the sides, perimeters, and areas of quadrilaterals, triangles, and circles. Students relate the measures to the others by using formulas.

Circles and Angles
Students identify tangents, chords and secants. In this geometry instructional activity, students graph circles and identify angles created by secant lines, tangent lines and chords.
Curated OER
Measuring Pots
Students use an activity sheet to construct analogies about possible function of ancient or historic ceramics and compute circumference from a section of a circle as they study measuring pots.
