Camping with a Triangular Prism and Its Net
Students differentiate triangular prisms from other prisms using nets. In this geometry lesson, students define the properties of a triangular prism and its symmetry. They build a triangular prism moving lines around.
Curated OER
Tangents to a Circle
Young scholars construct tangent lines. In this geometry lesson, students identify the point of tangency, secant and tangent lines. They graph the lines on the Ti and make observations.
Curated OER
Measuring the Earth
Young scholars identify types of arcs and angles in a circle, find the measure of arcs and angles, and solve real world problems involving lengths of segments in circles, lengths, and areas.
Curated OER
Conjectures For Intersecting Circles
Students identify properties of circles. In this geometry lesson, students identify the center of two intersecting circles.They use Cabri software to create circles and move it around to make observation.
Curated OER
Chors, Secants, Tangents
High schoolers identify the relationship between chords, secants and circles. In this geometry activity, students calculate the length of the chords. They sketch the secant lines on a circle.
Curated OER
Side Splitter Triangles
Students investigate the side splitter theorem. In this geometry lesson plan, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.
Curated OER
Constructing Perpendiculars
Young scholars construct perpendicular lines. In this geometry lesson, students use a compass and straight edge to do construction. They start from a point to a line.
Curated OER
Quilt Geometry
Seventh graders explore lines of symmetry, congruent polygons and patterns. They listen to "The Seasons Sewn," observe a PowerPoint presentation, and identify congruent polygons and visual patterns. Through an internet activity, 7th...

Vocabulary from The Outsiders
Learners listen to audio tape of segment of novel, The Outsiders, practice using online dictionary to look up and define vocabulary words, and create list of terms in Microsoft Word document.
Curated OER
Circle Packing
Young scholars identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.
Curated OER
Power of a Point
Students solve problems by finding the radius or diameter. In this geometry lesson, students identify the tangent line of a circle and use properties of circles to find the radius. They relate circles to the real world.
