Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Create a world of similar models. The geometry and measurement unit uses real-world scenarios to create models of familiar buildings and rooms. Scholars work with blueprints and scale models to compare areas and volumes between the...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

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

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

Instructions on a simple way to get started drawing in 3-D by drawing objects using an isometric grid.

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.

Can you help Leela find objects of different 3D shapes in her parents' tea store?
