Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Students explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

In this visual discrimination worksheet, students match the circle, triangle, rectangle, and square to the appropriate everyday objects that have those shapes.

Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.

Students estimate and measure exact. In this geometry lesson, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.

Students define and identify shapes by name. For this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Young scholars calculate the surface area and volume of a sphere. In this geometry lesson, students define nets, surface areas and volume of prisms, pyramids, cylinders and cones. They use the computer to create nets and analyze shapes.

For this counting shapes worksheet, students count how many squares, rectangles, circles, and triangles they can count in the picture of a house. Students count 45 shapes total.

Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry instructional activity, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret...

Name that shape! This simple worksheet has learners identify each geometric figure. They examine rectangular prisms, cylinders, rectangular pyramids, and hexagonal prisms. This one-page worksheet contains 8 problems, and the goals seems...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson plan to create 3...

Emerging engineers perform pre-lab calculations in this first of a three-part lesson on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of their...

Eighth graders study the cultural and architectural history of San Diego. After study they create a design of a home based of features from historical and modern homes found in their research.

Students design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.

Practice your knowledge of all possible cross-sections of common 3D objects. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Match 3D objects with their 2D cross-sections. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Basic practice problems involving cross sections of 3D objects.

Join Mel and Alba and find out more about 3D shapes and the position of objects.

The geometry resource investigates three-dimensional objects. Objects include prisms, cylinders, cones, and spheres. Detailed examples and practice exercises are included.

In this exercise, students practice finding the surface area of 3D objects. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.
