3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.
Curated OER
3-D Figures Part 2
Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
Curated OER
Three- and Two- Dimensional Geometry
In this three- and two- dimensional geometry worksheet, 7th graders solve 12 various problems related to geometric shapes and measurement. They first use paper and a pencil to sketch the front, side, back, top and bottom views of each...
Curated OER
Marshmallow Geometry
In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.
Curated OER
Exploring Projective Geometry
In this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.
Curated OER
Compare 2-D Shapes
Second graders examine the attributes of two-dimensional shapes. In this geometry lesson plan, 2nd graders play a game in order to identify two-dimensional shapes and to name them.
Curated OER
Shape Hunt
Young scholars explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Young scholars describe the attributes of their shape and...
Curated OER
Transformations
Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...
Curated OER
Mass Measurement
Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement activity, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...
Curated OER
Investigating: Finding the Volume
Sixth graders explore geometry by utilizing colored cubes in class. In this volume activity, 6th graders identify the different shapes they can create using their colored cubes and identify the formula for finding volume. Students create...
Curated OER
Problem Solving Using Power Polygons
Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...
Curated OER
Surface Area with Polydrons
Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...
