In this classifying shapes using Venn diagrams worksheet, students draw examples of isosceles, right, and equilateral triangles in the proper sections of the first graphic organizer. They draw polygons, both regular and quadrilaterals,...

In this parallel lines and proportional parts learning exercise, 10th graders solve 5 different problems related to determining whether lines are parallel and proportional in each figure. First, they refer to the figure shown at the top...

In this math worksheet, students complete the graphic organizers while filling in the missing values by using the trigonometric ratios.

In this math learning exercise, students find the solutions to the missing angles and sides of the triangles using the correct trigonometric ratios.

In this geometric shapes worksheet, students count how many triangles, rectangles, and circles they see and write down the numbers in the boxes provided.

In this math worksheet, students examine the two triangles and they compare them to each other. The shapes are measured and labeled as comparable to each other.

Students engage in a study of the Pythagorean Theorem to classify the hypotenuse of a triangle. The teacher uses examples from the activity to aid students in comprehension of solving problems that involve problem solving. They create a...

Seventh graders participate in a lesson that is focused upon the concepts of classifying different angles and triangles. They practice classifying triangles according to its kind that includes types of angles, congruence, and vertices....

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Learners explore about triangles and the simple machines that are made from those triangles. They are able to identify the kinds of triangles in the machines, tell how the triangular shapes make the machines function, and build a simple...

Fifth graders explore Pythagoras' Theorem. They examine the pattern linking the length of the hypotenuse of a right angled triangle and the length of the other two sides. Students find an unknown side in right angled triangles.

Fifth graders explore the importance of triangles in the real world. They find the unknown side of a right triangle using a scale drawing. Students use Pythagoras' Theorem and other appropriate ratios.

Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...

Young scholars are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Students build on existing knowledge of median and midpoints of triangles. They incorporate their prior knowledge to develop an example of the center of a mass of a triangle. They share their sketches with their classmates.

Twelfth graders apply perimeter measurement to items found in newspapers and calculate the cost in terms of feet or yards. They share answers and explanations with classmates.

Students explore how the Pythagorean Theorem works and how to apply it.

In this triangles activity, high schoolers solve 1 problem of multiple variables within a single picture of various triangles intersecting with a pair of parallel lines.

Students use problem solving skills, formal geometry, and The Geometer?s Sketchpad. They model and solve two real-world problems by constructing the in center and circumcenter of triangles.

Second graders investigate the task of making a large hexagonal plate by putting together smaller ones. The lesson has detailed example problems for the teacher to use during direct instruction. The manipulative activities strengthen the...

Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...
