Mr. Bo Jangle, What's Your Angle?
Third graders explore angles. In this geometry lesson plan, 3rd graders identify and define acute, obtuse, and right angles. Students form angles with their bodies, find angles in picture books, and record angles found outside in their...
Facing History and Ourselves
Analyzing Historical Evidence
High schoolers examine World War I war crimes. In this world history instructional activity, high schoolers use primary and secondary sources to research and understand the systematic nature of the Armenian Genocide. High schoolers...
Curated OER
Preparation and Transition to Two-Column Proofs
Students investigate proofs used to solve geometric problems. For this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...
Curated OER
Ancient Ones
Students read the story Ancient Ones about a forest that is connected to all the life around it. In this reading lesson plan, students also create a tall folding book about the forest.
Curated OER
Investigating Area Relationships
Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.
Curated OER
Inscribed Angles
Students calculate the inscribed angle of a triangle. In this geometry instructional activity, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.
Curated OER
All Around Triangles and Quadrilaterals
In this triangle/quadrilateral worksheet, learners use a centimeter ruler to draw triangles and quadrilaterals with given perimeters. Answers are included on page 2.
Curated OER
2-D Geometry
Third graders describe and compare attributes of two-dimensional shapes. They explain geometric terms, angles and shapes. Students demonstrate each vocabulary word with their body and they mirror the body positions associated with each...

Math with Maps and Globes
Students round out their math skills with these ‘round the world' ideas. In this math and geography lesson, students try out time zone sticks, a polar race, and tic-tac-globe to engage them in learning more about globes and the...
Curated OER
SAS Similarity Theorem
Students identify and use the similarity theorem. In this geometry lesson, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.
Curated OER
Concurrent Lines, Medians and Altitudes
For this geometry worksheet, students construct angles and identify medians and altitudes. They use a compass and protractor to perform heir construction. There are 28 questions.
Curated OER
Circumscribed Polygons
Students investigate polygons and construct ferris wheels. In this geometry lesson plan, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and circumscribed polygons.
