Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Have your class use online activities to recognize the names and properties of 2D and 3D shapes. They will listen to their teacher describe a mystery shape and try to guess it. Additionally they will watch clips online about a 2D shape...

Discuss the properties of 2D and 3D shapes in order to help learners understand the concept. Learners will participate in an interactive whiteboard lesson to develop understanding of 2D and 3D shapes.

Third graders describe 2D and 3D shapes. In this geometry lesson plan, 3rd graders watch a PowerPoint presentation showing the terms used when analyzing shapes: vertex, edge, angle, side, and face. They compare shapes to see what they...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students utilize the Poison Boxes activity on The Nature Park is used to practice the recognition of 2D shapes and their properties. They utilize a mathematics educational software program to gain practice.

Students identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.

Students define ellipses and their properties. In this calculus lesson, students analyze ellipses for their shape, center, major and minor axes. They create a paper ellipse to have a visual of what an ellipse really looks like in 3D.

Students create a bridge using engineering and geometric concepts. In this geometry instructional activity, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using...
