Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.

First graders find angles in their classroom. In this geometric figures lesson, 1st graders identify, describe and classify angles they see in their world. Students create pictures that contain angles and display them in the room.

Learners formulate a definition of tessellations by comparing and contrasting different patterns and shapes of real objects. They discuss the relatioship between shapes and patterns as well as their function in the real world. Students...

Students explore the concept of copying one another. In this early childhood lesson plan, students discuss what a copycat is and why people copy one another. Students then discuss the story Rainbow Fish: The Copycat Fish, recording...

Learners make art based on the ribbon work of the Woodland Indians. Background information on the art form and procedure are laid out in an easy to follow step-by-step format. 

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

n this geometric lesson plan, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

How do you know you know? Prove it! The guide goes through several examples and includes a link to a video to teach learners how to work through coordinate proofs. The goal is to prove that different shapes are indeed that shape. 

Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Here is a cute problem that requires visualizing two-dimensional shapes within a three-dimensional object, and using properties of triangles and the Pythagorean theorem to solve a real-world problem. There is a small mistake in this...

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

In this finding the area of geometric shapes worksheet, students observe parallelograms and trapezoids and use the information given to find their areas. Students solve 4 problems.

In this pattern recognition worksheet, students determine which shape comes next in nine strips of shapes and then draw that shape on the line provided.

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

In this sorting and graphing worksheet, students sort 15 objects and then fill in bar graphs to tell how many of each shape there are. The shapes are: heart, star and triangle.

10 this geometry instructional activity, learners identify the different angles created by polygons and name the shape created based on the number of sides. There is an answer key.

High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

In this circles and parabolas instructional activity, students follow directions to draw parabolas. They fold paper to represent a parabola. Students also use straight lines to create a circle. This one page instructional activity...

For this science learning exercise, students collaborate in performing an investigation regarding the best bridge construction for maximum strength. Students build several designs of bridges out of pins, straws, fishing line, and small...
