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...

Young scholars 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.

It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...

Scholars take transformations from the second to the third dimension as they extend their thinking of transformations to include three-dimensional figures. They explore how to use matrices to represent compositions of...

How many right triangles can you find in a prism, cone, or pyramid? Using right triangles to find lengths in three-dimensional figures is the focus of the lesson. After working with the Pythagorean Theorem to find missing side...

Some shapes have square corners, and some do not. Scholars participate in a sorting activity as they determine if these 12 shapes have square corners, categorizing them based on this attribute. Encourage geometers to draw the square into...

Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...

Students hone in on their skills at reading diagrams.  In this dimensional lesson students collect information on the functions of organs then figure out how all the parts work together. 

Here is a way to help your charges identify circles and spheres. In this shapes geometry and technology lesson plan, students identify and draw circles and explain the related attributes. They recognize circles and spheres while...

Students explore the concept of constructions, sketches, and drawings. In this constructions, sketches, and drawings lesson, students discuss the differences between constructions, sketches, and drawings through teacher led discussion.

Students describe geometric figures. They create pictures and list each shape they used to create their pictures. They discuss the importance of shapes in their lives and create ten different geometric shapes using the Drawing tools in...

Why do some stars in a constellation appear brighter than others? Using a get-up-and-move astronomy activity, scholars explore perspective and the appearance of constellations in the sky while developing an understanding of the...

Develop young mathematicians' knowledge of two- and three-dimensional shapes with this geometry workbook. From learning about the classifications of different shapes and figures to calculating their area, perimeter, and volume, this...

Learners use manipulatives to study shapes. They sort shapes and use correct geometric terminology to describe them. Students find real-life examples of 2 and 3 dimensional shapes, and classify figures in their classroom according to...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

First graders explore shapes. In this geometry lesson, 1st graders make shapes with geo-boards, use play-dough to make three-dimensional figures, and make a shape book using pre-cut shapes.

Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the...

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

What a great assessment to give young mathematicians in order to test their knowledge on two- and three-dimensional shapes. Learners name various shapes, identify the number of edges, faces, and vertices, match an unfolded version of a...

This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

Students explore various polygons and examine how shapes can be manipulated in a variety of ways. In this shape tool lesson, students identify geometric shapes in two dimensions. Students identify and draw one line of symmetry in a...

Students research art by identifying the work of Keith Haring. In this sculpting lesson, students utilize the web to examine sculptures and drawings in the style of Keith Haring. Students utilize sculpting wire, foil, pencils, glue and...

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...
