Students analyze the patterns in polygons and relate it to the rate of change. In this algebra lesson plan, students discuss the relationship between the data and the graph of the data.

Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, students use the TI to create a visual of their shape.

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.

Fifth graders apply the symmetry and angle properties of polygons and use fractions to express the relationships between the areas of rectangles, squares, and triangles. They analyze various country flags and develop mathematical...

Fifth graders study the metric and customary systems of measuring length with rulers, meter / yardsticks, and tape measures. They determine area of polygons and surface area and volume of three-dimensional shapes. They list as many...

Sixth graders use geoboards and dot paper to experiment with geometric concepts. For this geometry lesson, 6th graders complete four activities using geoboards or dot paper including naming points on a coordinate plan and finding the...

Tenth graders discuss the history of geometry as it relates to pentagons. In this geometry lesson, 10th graders solve problems of a pentagon inscribed inside of a circle using ratio. They review other properties for shapes of polygons...

In this secondary mathematics worksheet, students determine the reason that manhole covers are round and not polygonal.  The one page worksheet contains one problem with the solution.

In this geometry worksheet, students calculate the midpoints of polygons using coordinate pairs. They find the  angle bisector, altitude and median of the given triangles. There are 33 questions.

For this area worksheet, students commence solving for area of squares and rectangles, and continue to parallelograms and triangles, and continue again to rhombi and trapezoids and finish with circles, polygons, and shaded...

High schoolers calculate the altitude of triangles.  In the web based instructional activity, students explore the interior distance from a given point in a polygon to its side.  They compute the sum of these lengths. High...

Students calculate the volume of different polygons. In this geometry instructional activity, students identify the relationship between base and height. They calculate the area of each prism and cylinder.

The interactive lesson featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...

Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...

Sixth graders apply knowledge of how to calculate the area and perimeter of triangles. They determine why it is inappropriate to measure the area of land by its perimeter which is done in certain areas of New Guinea. They complete a...

In this geometry learning exercise, students find the area of four polygons. They compute the measure of an angle. Students find the length of the sides of a right triangle. They name one arc and find the measure of two arcs.

Geometers find the perimeter and area of rectangles. They discuss the definitions and characteristics of rectangles and squares. In groups, they use yarn to discover the perimeter of squares and rectangles. They count cubes to explore...

In this circumference activity, students solve and complete 5 different figures illustrated on the sheet. First, they cut out each shape found on the bottom. Then, students use the shapes on the left as clues to create the corresponding...

A one-pager featuring 2-D quadrilaterals.

Young mathematicians use their geometry skills to save the Land of Venn in an engaging math game. A fun way to reinforce children's understanding of basic geometric figures and shapes.

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

Make the connections between area, tiling, and multiplication. A performance task and associated unit presents the concept of area and makes the connection to multiplication. Pupils work through three major sections of instruction that...

Plan a dinner party. Using a book by Marilyn Burns as a context, pupils learn about the relationships between area and perimeter and surface area and volume. The hands-on activities have learners rearrange tables and cut up meatballs to...
