Circles and Clocks, Shapes and Time
Students work in groups to research clocks and practice telling time. In this telling time instructional activity, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles...
Curated OER
Arc Length and Sectors
Find the length of an arc. High schoolers relate central angles to the area and length of a sector and graph circles on the TI to make predictions.
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.
