Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...

Students identify shapes. For this geometry lesson, students cut out various shapes and create a "Shape Collage Pizza." Students glue their shapes onto a pizza template.

Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Students identify and name basic shapes and points. In this elementary geometry lesson, students use printable cut outs to name circles, triangles, and squares before playing a game with them. They play a game of "Pin the Tail on the...

In this equilateral triangles worksheet, students study the various triangles to identify equilateral triangles. Students may count the triangles.

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

In this transformations and translations in Geometry worksheet, learners use geometric shapes and grids to translate six transformations in each of two activities.

Shapes in art, shapes in stories, shapes in the environment, shapes all around. A multi-part lesson that includes looking at the artist Paul Klee's work, reading books about shapes, taking a walk in the neighborhood and identifying...

Students study about our dependence on the earth's resources for materials. They practice their knowledge of geometric shapes by recognizing them in the context of the story.

Students classify quadrilaterals, In this quadrilaterals lesson, students watch a video about parallelograms, discuss the different types of quadrilaterals, and complete a worksheet classifying quadrilaterals.

Are your geometry whizzes learning about angles and shapes? This online learning exercise gives 10 multiple choice questions based on images and word problems. Concepts include deducting angle degree, classifying shapes, and identifying...

Polly want a polygon? Young mathematicians sort shapes using an interactive. They classify the shapes as convex polygons, concave polygons, or not polygons.

In this tangram worksheet, learners find the area of each tangram shape. Afterwards, they name each piece and find the area of combined figures. This one-page worksheet contains approximately 25 problems.

Working on symmetry in your class? If so, this worksheet might be for you. Learners observe different triangles and quadrilaterals, determine which are symmetrical, draw in the lines of symmetry, and color the symmetrical shapes. In...

Stretch your mind about triangles. Given a triangle, scholars consider a smaller triangle formed when they stretch three rubber bands from each vertex to the opposite side. They determine the ratios of the areas and perimeters of the...

In this quilt patterns worksheet, 7th graders identify and complete 6 different problems that include various patterns using shapes. First, they fill the square with the polygons listed on the left as stated. Then, students use...

In this geometry worksheet, students identify different kinds of triangles. Students are given four triangles with their measurements and are to determine which triangle it is by choosing from six different kinds.

In this geometry skills learning exercise, students respond to 6 questions that require them to examine geometric shapes and identify them as circles, squares, triangles, or rectangles.

Learners research how engineers and scientists generate linear and angular measurements with geometry to survey the Earth and Mars. They assess how geometric shapes affect navigation. A surveyor comes to the classroom and explains how he...

In this area learning exercise, students find the area of ten figures that are drawn on a coordinate grid. Five of the shapes are triangles. Five shapes are irregular quadrilaterals.

In this triangles worksheet, 10th graders solve 10 different problems that include determining the measurement of various angles. First, they determine the area of a triangle illustrated on the sheet. Then, students use the picture to...

In this identifying shapes worksheet, students tell which shapes in sets are named, choosing from cube, triangle, cone or sphere. A reference web site is given for additional activities.

In thins triangles review worksheet, students examine 4 triangles and their measurements. Students classify them as equilateral, isosceles, or scalene.

In thins triangles review worksheet, students examine 3 triangles and their measurements. Students classify them as acute, right, obtuse, equilateral, isosceles, or scalene.
