Your geometry learners are guided by questions that help them use the language of reflections to explain the Side-Angle-Side congruence between two triangles in this collaborative task. Given a sample solution, declaring the...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Your geometry learners explore Angle-Side-Angle congruence in this collaborative task. The sum of the interior angles of all triangles being one hundred eighty degrees, is the key learners will discover as they explain their reasoning...

Your learners will make good use of the Socratic method in a collaborative task that begins with an assumed solution and ends with deeper understanding of the idea of determining two triangles congruent.

Learn about constructing figures, proofs, and transformations. The seventh unit in a course of nine makes the connections between geometric constructions, congruence, and proofs. Scholars learn to construct special quadrilaterals,...

Discuss how political postcards affected everyday people's thoughts and beliefs. Pupils continue a unit on the Dreyfus Affair as they engage in class discussion, watch a video, view a PowerPoint presentation, and fill out worksheets to...

Historical events do not occur in a vacuum. Such is the case of the Dreyfus Affair, where the connection between Captain Alfred Dreyfus, Emile Zola, and Hannah Arendt is fused by the events of the early 20th century. The informative...

Construct yourself a winning geometry unit. A set of lessons introduces geometry scholars to constructions and proofs with compasses and straightedges. It also covers triangle congruence through transformations. This is the second of...

This task asks learners to prove that the segment joining the midpoints of two sides of a parallelogram is both congruent and parallel to an adjacent side of the parallelogram. The activity would be good to use in a discussion about how...

Students complete poetry writing activities and art analysis activities. For this creative writing and art lesson, students analyze a cubist piece by Picasso and discuss abstraction. Students read a poem by Gertrude Stein about Picasso...
