Students identify properties of parallelograms. In this geometry lesson, students label polygons as parallelogram or not. They define and label the properties of a kite.

Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.

Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.

Twelfth graders apply the formula for finding the area of a triangle to various problems. They work real life problems for finding the area of a bathroom and the cost of tiling it. They play a game, Triangle Bingo, where they match...

Students demonstrate the relationship between stress and strain, then graph stress-strain curves for various common materials. Students interpret graphed results and discuss differences in mechanical properties of materials.

Students watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record their...

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Use this task as an exit ticket for your eight graders during the geometry unit. All they need to do is identify the coordinates of a point reflected over y=2000. 

Young scholars experiment with straight edges and compasses to divide lengths into equal parts. They identify different fractions of the total length.

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Students develop an appreciation of the use of geometry in our everyday world and structures. Students collect various picures and multimedia objcets that explain geometric principles and place them in a powerpoint presentation to be...

Eighth graders explore the characteristics of a circle and the formulas to find circumference. They use a bicycle wheel to determine the circumference around a wheel. They utilize a worksheet imbedded in this plan which has a variety of...

Young scholars are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to...

Stuck trying to remember the formal language of a geometric proof? Never fear, this handout has them all ready to go. The reasons are sectioned by topic so this handy guide is ready when you are to tackle those two column proofs. 

In need of math vocabulary cards? Use a set of 66 vocabulary cards with topics focused mostly on geometry terms. Each sheet has two cards on it. The top half has the word printed in bold text, while the bottom half has the card with...

Is the amount of information getting overwhelming for your geometry classes? Use this strategy as a way to organize information. The resource provides a handout of information studied in relation to triangle congruence. It includes a...

Fifth graders work with polygons.

Second graders describe a polygon in the form of a riddle.

What type of quadrilateral is that? Discover the difference between the types of quadrilaterals. Small groups investigate types of quadrilaterals using geometry software to find their properties. To keep track of the different...

In this math learning exercise, students examine the graph of the derivative. Then they determine the critical points that correspond to the relative extrema.

In this indirect Euclidean proof worksheet, learners write statements supporting the reasons for a given proof. This one-page worksheet contains ten problems.

In this online interactive math skills worksheet, students solve 10 multiple choice math problems regarding geometry skills. Students may view the correct answers.

In this math worksheet, students observe that the triangular numbers are associated with the sums of consecutive natural numbers beginning with 1.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...
