Identifying Lines of Symmetry
Students calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.
Curated OER
Studying Special Segments in Triangles
Students investigate special segments in triangles. In this geometry lesson plan, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
Curated OER
Mathematics in Robotics
Learners build and create using math. In this geometry instructional activity, students differentiate between congruent and similarity as they observe polygons. They create robots with different functions using properties of geometry.
Curated OER
Congruent Boxes
Learners decorate the congruent faces and edges of boxes in exactly the same way. They teach the terms "congruent," "faces," and "edges" to their parents.
Curated OER
Give It a Whirl
Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.
