No Edge, No Center -- Exploring the Shape of Our Universe
Students examine various "spaces" (including ones that are one-dimensional, two-dimensional, and three-dimensional). For each space, they will examine what it means to have or not have an edge, or to be finite or infinite.

Ellsworth Kelly
Young scholars examine and discuss artwork by the artist Ellsworth Kelly. They create an abstract picture of two-dimensional geometric shapes using Kid Pix software based on a photograph taken by the student.

No One's a Winner!
Students create two-dimensional maps showing the affects of a dam on those living both above and below the dam. Students discover the importance of educating the public before the construction of a dam.
Curated OER
Sneaky Peeky Symmetry Book
Students examine lines of symmetry with different shapes. Then students create their own books of symmetry with different two-dimensional shapes on each page.

Spyglass
Students distinguish between visualization and scientific visualization. They use the software program Spygalss to create images from two-dimensional arrays of numbers.
Curated OER
Earthquake Unit
Eighth graders watch the "Earth, the Environment & Beyond" video on earthquakes. Take notes and give an oral summary. They build a working, two dimensional model of a strike-slip, thrust, or normal fault.
Curated OER
Ship Shape
Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.
Curated OER
Parks Design Project
Students explore two dimensional geometric figures. They explore the relationships and measurements of geometric figures. Students apply proportion and scaling. They design a city park for students and teenagers.
Curated OER
Sign Language 2 (Found Object Sculpture)
Third graders develop their symbol three-dimensionally.
