Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
Curated OER
Polygons
Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.
Curated OER
THE MEAN INDEX CARD
Middle schoolers cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Geo Jammin' By DeSign - Day 2, Lesson 9: Bringing It To A Fine Gloss-ary
Young scholars create a glossary of geometric terms while exploring tangram manipulatives.
Curated OER
Symmetry of Road Signs
Young scholars identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

Medieval Mathematicians and Whimsical Windows
Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.
Curated OER
Tiling the Plane
Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...
