Parallel and Perpendicular Lines
Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.
Futures Channel
Folding Circles
Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.
Curated OER
Circles and Clocks, Shapes and Time
Young scholars 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...

Sketching Prisms
Students sketch and create nets of different polygons.In this geometry lesson, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
Circle Art
Students investigate two and three dimensional shapes. In this geometry instructional activity, students write equations of circles and graph them correctly. They create pictures using circles.
Curated OER
Polygons And Polyhedra
Students 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 students will extend the study of polygons to...

Symmetry of the Southwest
Fourth graders examine mirror symmetry. In this symmetry lesson plan, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.
Curated OER
Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
