Most objects have irregular dimensions — you have to find them! Teach your class how to find the volume of composite objects that can be decomposed into prisms. Objects get increasingly more complex as the lesson progresses.

Expose youngsters to 3-D objects in a hands-on learning activity involving marshmallows and toothpicks. Engage your young mathematicians by introducing them to 3-D shapes by means of a story book. Explore 3-D shapes by manipulating...

Students explore pyramids. For this math lesson, students discuss where they have seen examples of pyramids. Students classify pyramids as three-dimensional figures and identify their attributes.

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...

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...

It's amazing the complex figures that can be made using only a few simple shapes. Following a class reading of the children's book Grandfather Tang's Story by Ann Tompert, young mathematicians use sets of tangrams to create models...

To determine the dimensional change to quadruple the area, class members determine how to increase the dimensions of a square and a circle to increase the perimeter by a given factor. they then calculate the necessary factor to...

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...

In this nets of 3 dimensional figures worksheet, students determine which given figures will make given nets, then name a set of 4 shapes.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

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. 

First graders explore 2-dimensional and 3-dimensional shapes. In this geometry lesson, 1st graders examine the attributes of 2 -dimensional and 3-dimensional shapes. They also create the shapes as they build models. This lesson...

In this congruency worksheet, students complete problems dealing with congruent and non-congruent figures. Students complete 5 short answer and multiple choice problems.

Students make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

Geometers construct a mobile or ornament using nets of three-dimensional polyhedrons. Not only do they need to compute the volume and surface area of each figure, they also earn points for creativity, neatness, and more!

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...

These pictures will cost you! Each shape is worth a money amount. Scholars use this value system to price four images composed of these shapes. There is an example to help them get started which demonstrates labeling each shape before...

Building a six-sided number cube has never been so easy. Just cut out the figure on the solid lines, fold on the dotted lines, connect the sides together using glue or tape, and there you have it!

Young scholars play a bingo game to classify 3 dimensional shapes. In this 3 dimensional shapes lesson plan, students identify, describe, and classify shapes by playing a bingo game.

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...

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...

Creating with an app is nice. But, creating with an app and being able to print and use your creation is great! This tool provides the opportunity to hone the skills related to spacial awareness, three-dimensional thinking, creativity,...

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...

Hand your incoming scientists a collection of helpful worksheets to introduce them to your chemistry class. The packet addresses exponents, scientific notation, metric conversion, and dimensional analysis.
