Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
Curated OER
Create Your Own Family Crest
Students develop a design for their own family crest. Students make a large model crest for their family.

High School Mathematics Problems from Alaska: Azimuth and Arc Length
Students track the Azimuth sunrise and sunset over time by creating a chart.
Curated OER
All Messed Up
Pupils begin the experiment by mapping and calculating their school parking lot. They calculate the volume of water falling on the lot and map the route the water runoff takes. They discuss the roles that humans play in affecting water...
Curated OER
Angles and Arcs
Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs.
Students give examples of concentric, similar, and congruent circles and congruent arcs.
Curated OER
Math: Arcs and Chords
Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...
Curated OER
Math: a World of Symmetry
Learners expand their knowledge of quadrilaterals and identify basic symmetrical forms. Over three weeks, they explore the math, application, and discussion of symmetry. After conducting Internet research, students create symmetrical...
