Students investigate right angles. In this geometry lesson, students define the word "angle" and create a right angle finder from an index card. Students find right angles in their classroom. As an extension activity, students try to...

Challenge young mathematicians' ability to compose and decompose shapes with this fun geometry puzzle. The goal is simple, locate all of the rectangles shown in a picture of three overlapping rectangles. Perform this activity as a whole...

What effect does changing the perimeter have on the area of a figure? The five problems in the resource explore this question at various grade levels. Elementary problems focus on the perimeter of rectangles and irregular figures with...

Students explore geometric shapes by creating them through paper.  In this geometric shape lesson, students bend, cut and shape paper to create geometric shapes.  Students discover how many ways they can produce new shapes....

An outstanding lesson plan on teaching the basic shapes and polygon names to young geometers is here for you. In it, learners investigate the role of basic polygons in the strength of structures. They use geoboards, rubber bands,...

Dedicate one or two class periods to creating a class glossary of geometry terms. Many geometry terms also appear in our every day vocabulary, but they have very different meanings. For example, the word gross in geometry is very...

Youngsters explore visual arts by participating in a geometry identification activity. They read the book The Very Busy Spider and identify the techniques spiders use to create webs. Have you ever noticed that their webs are geometric...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Lower elementary learners recognize solid shapes distributed for making fractions. Each individual uses a wheel and determine which part of a fraction is missing. This is a great lesson plan for your visual learners!

Students identify 3-dimensional geometric shapes and list the characteristics of each. Using modeling clay, they create their own models of specified geometric shapes. Students create and design a box to store their geometric models.

Third graders investigate congruent polygons through dance. In this congruency lesson plan, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Students gather information about the Melbourne Cup horse race in Australia. Then they study the geometry and physics behind the design of a racetrack. Students also work in small groups to problem solve and design their own board games...

Bring math and reading informational text together with a reading comprehension lesson. After kids read about isosceles, scalene, and equilateral triangles, they answer five comprehension questions to demonstrate how they can use context...

Learners explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Learners create examples of tessellations using pattern blocks.

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Students create geometric shapes with a jump rope. In this interdisciplinary lesson, students review the different shapes while getting some physical activity.

Student complete worksheet using the definitions of lines and angle vocabulary. They define the word and follow a direction given on the worksheet such "construct a line." They complete an online tutorial on how to measure angles using a...

Students use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this instructional activity. They make a set of tangrams and use them to...

With the help of the Area Officers and Perimeter Patrol, you learners will develop a better understanding of area and its relationship to perimeter. First, they view a video clip from Cyberchase, and then they visit a website to...

Use shapes to visualize fractions! Elementary learners color 1/2, 1/3, 1/4, 1/8, and 1/10 of various shapes. A great addition to your fractions lesson, or to introduce geometry in your math unit.
