Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Students find the perimeter and area of circles, triangles, and rectangles. For this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no creative...

Third graders discover geometric shapes by completing a series of games and activities. Using ropes with knots tied every foot, they make shapes such as squares, triangles, and hexagons. In pairs, 3rd graders use pattern blocks to...

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this activity to create 3...

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

In this area worksheet students read story problems, determine the necessary information to solve the problem. They find the amount of material needed to construct three-dimensional figures. Students determine the greatest and least area...

Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.

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 engage in a lesson that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the importance of...

In this geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.

Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, young scholars identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and...

In this geometry worksheet, learners construct polygons and calculate the different angles formed by each shape. They construct circles, trapezoids, and rectangles and answer 20 questions.

Learners 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.

Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.

In this geometry activity, students solve problems based on the triangle inequality theorem(s) in which determine if the given lengths can form a triangle, given two sides of a triangle determine the range of the third side, and order...

In this algebra instructional activity, students review the basic concepts of algebra and linear equations. They solve polygons and shapes for their area and perimeter. There are 27 questions.

Shapes are all around us! Kindergartenrs identify shapes in their world and guess the shape being described. They participate in a shape hunt.

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...

Students create tessellations. In this geometry instructional activity, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.

Fourth graders explore obtuse triangles. In this geometry lesson, 4th graders make obtuse triangles with paper and scissors. They determine how to find the center of their triangle.
