Curated OER
Relating Algebra to Geometry
Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.
Curated OER
Orthographic Drawings
Learners investigate the creation of three dimensional drawings. In this geometry instructional activity, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.
Curated OER
Orthographic Drawing
Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.
Curated OER
Three Dimensional Solids
In this geometry worksheet, 6th graders examine 3 isometric drawings and match them to 3 three-dimensional solids. They draw the front, side, and top views of 3 three dimensional solids by depicting the unit cubes that were used.
Curated OER
Exploring Projective Geometry
In this exploring projective geometry worksheet, learners use computer software for instruction, then answer 9 questions about 3D drawings.
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.

Surface Area and Volume
You and your class will like this lesson plan on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and...
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
Curated OER
Polydron Fun
Learners investigate nets as they relate to volume and area. In this geometry instructional activity, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about...
Curated OER
Exploring Area
Tenth graders calculate the area of various shapes. In this geometry lesson, 10th graders use isometric paper to draw shapes. They identify their shapes by name and calculate how many triangles will fit in the area of a shape.
Curated OER
Modular Houses
Learners, working in pairs, are presented with the problem. They are asked to design modular houses using four cubic modules, all the same size, which touch each other on complete faces. They must draw each of their houses on isometric...
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
Net "Working"
Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...
