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...

Sew up pupil interest with an engaging, hands-on lesson. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses of included...

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.

Students calculate the surface area and volume of a sphere. For 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.

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Master place value with a series of lessons that use math journals, manipulatives, and place value mats. Kids follow the instructions to represent numbers of all sizes with base ten blocks and recording sheets. 

Learners play a game with shapes. They work in groups to identify the names and characteristics of various shapes. They give each other clues to see if others can identify the shape being described. This is a great hands on activity.

Students 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...

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...

Learners create a three dimensional model of a cell. In this cellular structure lesson, students use gelatin, plastic bags, plastic containers, and fruit to construct a model of a cell. They compare the cells structures and stack them to...

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.

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.

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...
