Red Circle, Red Circle, What Do You See?
Young learners explore shapes and colors. They listen to Brown Bear, Brown Bear What Do You See? by Bill Martin Jr. and use the same language pattern to create a color and shape book of their own. After that, with the leftover magazine...
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: Tangents
Students discover how to recognize tangents and how to use their properties. They investigate and use the properties of angles, arcs, chords, tangents, and secants. Students use two tangents and the properties of similar triangles to...
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.

Connecting Formulas Related to Geometric Figures
Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.
Curated OER
Shaping Your World
Learners describe geometric figures. They create pictures and list each shape they used to create their pictures. They discuss the importance of shapes in their lives and create ten different geometric shapes using the Drawing tools in...
