Soft Sculpture Birds
Art can mimic life, and animals are always interesting subjects. Learners create large soft sculptures (stuffed) birds using paper, paint, and other basic collage materials. They view images of birds, and discuss bird traits and shapes....
Curated OER
Let's Tesselate
Students investigate the geometrical concepts of translation, reflection, and rotation. They make different observations looking for the concepts that are displayed in classroom items like floor tiles, carpet designs, and visuals hung in...
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.

Easy and Artistic Printmaking Using Mixed Media Materials
Students explore printmaking which began with the ancient Chinese who carved seals from stone, inked them and used the seals as identification symbols. They produce a print in this lesson.
Curated OER
Grade 5: Testing for Tessellations
Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Introduction To Melodic Notation: Sol-Mi
Second graders discover the use of melody in music and how it relates to simple songs and music notation. Students sing and move throughout this lesson. Emphasis is placed upon group and individual practice interpreting musical melodies.
Curated OER
Fractals Rock
Students identify the repeated sequences of a pattern. In this geometry lesson, students identify fractals in patterns and nature. They construct a fractal tree and make conjectures.
Curated OER
Creating Adinkra Symbols
Students discover examples of adinkra cloth. They explain the history of the symbols themselves. They create a larger pattern using geometric symbols. They discover how the symbols can be used to communicate with one another.

Triangle Inequality Theorems Investigation
Young scholars estimate and measure triangles. In this geometry lesson, students identify the relationship between three sides and a triangle. They use the inequality theorem to decide if a triangle will be formed or not.
Curated OER
Functions and the Vertical Line Test
Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.
Curated OER
Comparing Costs
Learners compare the costs of two cellular phone plans and determine the best rate. They use a table and a graph of points plotted on a Cartesian plane to display their findings. Students write an equation containing variables that could...
