Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon instructional activity, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
Curated OER
Polygons Defined
Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.
Curated OER
Symmetry of the Southwest
Fourth graders examine mirror symmetry. In this symmetry lesson, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.
Curated OER
Art Using Sequence
Students are introduced to representative works of various artists including Paul Klee, Piet Mondrian, Sonia Delauny, Henri Matisse, Joan Miro and Henri Rosseau. They read books, participate in discussion and create original works of art.
Curated OER
Justifying Mathematical Conjectures
Sixth graders, in groups, explain why they think something. This requires students to listen to and respond to each other. In this particular lesson, 6th graders explain to their classmates when one can or cannot construct a specific...
Curated OER
Shape It
Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...
Curated OER
Geometric Shapes at the OK Corral
Students explore geometric shapes. In this math lesson, students identify geometric and non-geometric shapes using the computer. Students research geometric shapes in art and architecture.
Curated OER
Geometric Shapes at the OK Corral
Students explore regular geometric shapes. In this shapes lesson plan, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.
Curated OER
Similar Triangles
Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.
Curated OER
The Strongest Shape
Students work collaboratively to design and construct a roof out of Legos for a house that was built in a previous lesson. The roof must be structurally sound and pass certain criteria determined by the teacher.
Curated OER
Clock Arithmetic and Cryptography
Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.
Curated OER
Clock Arithmetic and Cryptography
Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their ciphers...
