Math: Symmetry and Similarity
Students describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist...
Curated OER
Plane and Solid Figures
Students define a plane and a solid shape. In this geometry instructional activity, students compare and contrast different geometric shapes as they relate to solids. They name the geometric solids based on their sides and edges.
Curated OER
Geometry and Measurement
Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Congruent Shapes
First graders view congruent shapes on a white board and define what congruent means. In this congruent shapes lesson, 1st graders recognize which shapes are congruent and which aren't Students complete a giant worksheet in...
Curated OER
Space Geometry
Students explore points, lines and planes as it relates to geometry. In this geometry lesson plan, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.
Curated OER
Marshmallow Geometry
Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson plan, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...
Curated OER
Plane Shapes and Solid Figures
In this math worksheet, students study the properties of plane shapes and solid figures. Students fill out a chart after they have calculated the number of flat surfaces, edges and vertices.
Curated OER
Castles
Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.
Curated OER
Identify Faces
In this solid shapes worksheet, students learn to identify solid shape faces. Students identify the solid shapes and the faces in the six word problems.
Curated OER
Circles to Spheres
Students investigate circles and spheres. In this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Students investigate the relationship between plane and space shapes.
