Curated OER
Light Bounce
Students solve problems involving triangles. In this geometry instructional activity, students apply properties of triangles to find the missing angles and sides. They identify angles of parallel lines cut by a transversal.
Curated OER
Triangle Exterior Angles Theorem
Students identify the measure of missing exterior angles. For this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.
Curated OER
Making Parallel Lines
Students differentiate between parallel and perpendicular lines. In this geometry lesson plan, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.
Curated OER
Focusing on Lenses
Students explore scientific observations by examining the parts of a microscope. In this optics lesson, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a microscope. Students...
Curated OER
Geometry House!
Fourth graders use computer drawing tools to create a house of geometric shapes.
Curated OER
Venn Diagram Lesson Plan
Students use Venn diagrams in order to classify different objects and numbers. They then use "Venn Diagram Shape sorter" applets on the computer.
Curated OER
2-D Geometry
Third graders are introduced to new vocabulary related to Geometry. As each word is mentioned, they demonstrate the word with their body. In groups, they identify the similarities and differences between each line and angle. To end...
Curated OER
Making Tangram Pieces by Folding Paper
Third graders follow directions to make a set of tangram pieces. After reading a story, they compare and contrast the differences between two-dimensional shapes. To end the lesson plan, they use the tangram pieces to create their own...
Curated OER
Basic Geometry Ideas and Angle Measurement
Seventh graders explore the concept of basic geometry. In this basic geometry lesson, 7th graders identify the correct picture for a given vocabulary word such as midpoint, line, ray, or parallel lines. Students discuss examples of...
