Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

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.

Tenth graders are provided instructions, including a video, on calculating the surface area of a prism. The one-page interactive worksheet contains two worked questions. Answers are included. 

Students analyze characteristics of various 2 dimensional shapes and explore their properties and use various vocabulary terms to discuss geometric relationships.

Learners explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Students identify polygons.  In this polygon people lesson, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The lesson may be extended by allowing students...

High schoolers investigate quadrilateral construction in this geometry lesson. They use Cabri Jr. to construct the different quadrilaterals from the quadrilateral hierarchy given minimal definitions. The lesson reinforces the difference...

In this geometry review game worksheet, students use the provided game cards and calling cards to play a Bingo-like game. Students learn geometric terms while playing a group game.

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

In this geometry worksheet, 10th graders examine the effect of changing the dimensions of a figure proportionally on the perimeter, circumference, and area.  The one page worksheet contains six problems.  Answers are...

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

Seventh graders organize a 20 x 17 room with a given set of furniture pieces. Arrangement is to be based on maximum comfort and practicality. This lesson is a good way to teach and reinforce the mathematical concept of area.

Students investigate how to make a good parachute. In this physics lesson, students observe the motion of parachutes as it falls and measure the time. They collect data and calculate the average descent time for each canopy shape.

For this all about quadrilaterals worksheet, students interactively answer 10 multiple choice questions about quadrilaterals, then click to check their answers.

In this polygons learning exercise, students classify each polygon in as many ways as possible. Students then write polygon or not a polygon to classify each figure and find the measure of the missing angles. Students finish with one...

In this geometry worksheet, students define and draw quadrilaterals. They differentiate between the different shapes. There are 3 questions with an answer key.

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

Learners calculate the slope of parallel and perpendicular lines.In this algebra lesson, students differentiate between parallel and perpendicular lines. They graph their lines using the slope of the equation.

Students find the slopes for perpendicular and parallel lines. In this geometry lesson, students differentiate between parallel and perpendicular lines. They use Cabri software to create lines to compare.

Fifth graders use estimation to solve word problems. In this fractions instructional activity, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation....

In this geometric shape worksheet, learners respond to 4 questions that require them to connect the midpoints in the 4 figures and identify the new shape the connections create.

In this geometry skills lesson, students respond to 4 questions that require them to examine the pictured shapes and follow the instructions to create new shapes out of them.
