The Geometry of Indigenous Art
Young scholars examine the concepts of symmetry, rotations, reflections, translation, dialations, and tessellations and apply them to indigenous art. They also do Internet research and create artwork (painting, pottery, computer graphic...
Curated OER
Tangram Tantrums
Students discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.

Triangles in Architecture
Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.
Curated OER
Fractals
Students explore the concept of fractals. In this fractal lesson, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...
Curated OER
Data Representation
Students solve real life scenarios using math. For this geometry lesson, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.
Curated OER
Round and Round and Round We Go!
Students investigate motion using a CBL. In this algebra lesson, students collect and graph data on a coordinate plane. They define and identify amplitude and period of conic graphs.

Geo Jammin' - Day 4, Lesson 12: Geo Gee-Hawin'
Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.
Curated OER
Symmetry
Students make a design with pattern blocks and then pass them on to the rest of the class. They have to make them symmetrical and complete the design.
Curated OER
Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.
Curated OER
Measurements
Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.
Curated OER
Online Interactive Math: Upper Elementary: Mixed Skills
In this online math learning exercise, learners complete a 20 problem multiple choice online interactive learning exercise with mixed skills including geometry, rounding, and three digit multiplication.
Curated OER
What Makes A Face A Face?
Students discuss what enables us to read a face: features, expressions, standards of beauty, age and gender. They discuss what enables us to read motion: repetition, sequence, changes in form and scene.
Curated OER
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.
