Two-Dimensional Objects

Three dimensional objects are not flat! Young learners explore 3-D shapes and their many faces. Have them find some of the 3-D objects in their environment, such as: spheres, rectangular prisms, cones, cubes, cylinders, and pyramids....

"How can you help students visualize numbers in a way that is compatible with our base-ten number system?" The answer is simple: use ten-frames. Whether they're being used as a part of classroom routines or as instructional tools, this...

Young mathematicians explore the beauty of geometry with this cross-curricular math and visual arts lesson. Over the course of four or five days, children observe and discuss the geometric and organic shapes found in two pieces of...

Entertaining as well as educational, this math activity about decomposing numbers is bound to capture the engagement of young learners. Given a cup and five two-color counters, young mathematicians simply shake and spill the cup,...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

A collection of two lessons, kindergartners will identify two-dimensional shapes in solid shapes. They will develop basic knowledge of the components that make up a sphere, rectangular prism, pyramid, cylinder, cone, and cube. Young...

In search of a comprehensive geometry resource to supplement your elementary math instruction? Look no further. This geometry chapter, taken straight out of a math textbook, provides everything you need to begin teaching young...

Number 2 is star of a music video featuring a friendly duo that points out pairs of objects—gloves, ears, shoes, and more!

Create three dimensional objects in an applied science lesson. The goal is for your class to recognize, compare, and model shapes. Using cookie cutters and clay or play dough, they create models for three-dimensional shapes.

Bring three-dimensional shapes to life in your classroom. First introduce the vocabulary of three-dimensional shapes, such as sphere, cube, and pyramid. Then, show your kids examples of how to use two-dimensional objects draw...
