Curated OER
Understanding Reflections by Paper Folding
Students investigate reflections and rotations. In this geometry lesson, students perform hands on experiments as they study reflections in the axis and over a line. They investigate human factors and work physiology, relating it to math.

Governor's Garden
Young scholars review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...

Tessellations: Geometry and Symmetry
Students examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling to...

It's a 3-D World Out There!
Students construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Students use K'NEX materials sets to...

Twenty Questions: Fourth Grade Math Terms
Questions related to math vocabulary from a large variety of categories for 4th graders are displayed throughout this Jeopardy game. Concepts covered include angles, shapes, computation terms, statistics, and place value.
Curated OER
Plain Figures And Measuring Figures
Seventh graders investigate the mathematical concept of a sector. They apply the concept to an example problem and then move into a more complex application. They find the area of the side of a cone. This is done as students calculate...
Curated OER
Tantalizing Tangrams
Fourth graders participate in what is considered to be a model lesson. The lesson focuses upon polygons and basic geometry. The lesson addresses national standards and displays how others should be done.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The activity and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
Tangrams
Students construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with the...
Curated OER
Tangram Perimeters
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.
Curated OER
Circles and Clocks, Shapes and Time
Learners work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....
