Polygons And Polyhedra
Pupils recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of pupils will extend the study of polygons to quadrilaterals.
Curated OER
Polygons and Plane Figures
Learners choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Self Check Practice
For this planes worksheet, students solve 5 multiple choice problems. Students determine which planes intersecting create a given line. Students determine which point is coplanar with three other ones.
Curated OER
Polygons Defined
Fourth graders explore polygons. For this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.
Curated OER
Geometric Shapes at the OK Corral
Students explore regular geometric shapes. In this shapes activity, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.
Curated OER
Congruency Basics
Fourth graders investigate congruent shapes. In this congruency lesson, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.
Curated OER
Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
