Basic Visual Language
Students gain knowledge of the basics of visual communication. They are introduced to the three fundamental elements of visual language. Those are: camera angle, lighting, and compositions. Students video each other from different angles...
Curated OER
Shadows and Skyscrapers
Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...

Tetrahedron Kites
Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...
Curated OER
Frieze Patterns And Tiles
Students investigate geometry with the use of a creative project. They review relevant vocabulary that includes turn, flip, side, and angles. Students also practice conducting transformations used as inspiration for the project. Then...

Solar Car Races: Build and retrofit for speed
If you have solar car kits for your junior high schoolers, they can experiment with photovoltaic cell angle, light intensity, and aerodynamic design to discover what makes their car move more quickly. This is a classic activity to use...
Curated OER
Isosceles Triangles
Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...
Curated OER
Marshmellow Geometry
Young scholars explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

Mathematics in Art?
Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...
Curated OER
Quilt Geometry
Seventh graders explore lines of symmetry, congruent polygons and patterns. They listen to "The Seasons Sewn," observe a PowerPoint presentation, and identify congruent polygons and visual patterns. Through an internet activity, 7th...

Goldsworthy Project: Building With the Five Elements of Art
Seventh graders explore the five elements of art: line, shape, value, texture and color. They collect items from nature and arrange them aesthetically taking the five elements into consideration. They consider their work from several...
Curated OER
Application of Delta-Epsilon Definition of the Limit
Students create a Hexaflexagon using a formula. In this calculus lesson, students apply the definition of delta epsilon as it relates to limit to create a shape using creases. They relate the same rule to triangles and investigate angles.
