Here is a way to help your charges identify circles and spheres. In this shapes geometry and technology lesson, students identify and draw circles and explain the related attributes. They recognize circles and spheres while exploring...

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.

Fourth graders view and identify three-dimensional figures. They analyze and discuss various figures, build three-dimensional figures, and complete various worksheets and worksheet discussion questions.

Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

Students compute the surface area of 3 geometric solids to determine the shape of package that would require the least amount of paper to wrap. In this geometry instructional activity, students work on a two-question assessment embedded...

Learners explore scale factor as they create a scale drawing of a box, then determine the surface area and volume of the original and the scale drawing. The one page worksheet contains activities and procedures with four questions....

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

First graders identify geometric solids. In this shapes and solids beginning geometry lesson plan, 1st graders reach into a bag and identify the geometric solid they feel. Students describe shape attributes and match two dimensional...

In this plane figure worksheet, students complete 4 multiple choice questions, determining which solid figure can be traced to make a given plane figure. A reference web site is given for additional activities.

If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the activity develops the definition of a general cylinder. Scholars continue on to develop a graphical organizer...

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

In this math worksheet, students build a truncated dodecahedron. This is a solid shape with 12 regular decagonal faces and 20 equilateral triangular faces. Students build this shape to assist in developing their cognitive and geometric...

In this geometry worksheet, students analyze 9 drawings of geometric shapes and solid figures. Students write the name of each shape. There is no word bank.

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Third graders construct a dodecahedron that displays facts about two and three-dimensional figures. They use a pattern to construct a dodecahedron after writing facts about geometry onto each of the figure's twelve faces.
