Travel using a compass. Get your bearings! What does that mean? Choose a starting point, set your bearings, move to a location, and then use your bearings to return to the original starting point. It is of utmost importance to understand...

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Students discover that the sum of the lengths of any two sides of a triangle must be greater than the third side. They are shown how a triangle is formed using three strips such as that the triangle is seen inside the strips.

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...

Middle schoolers study the triangle inequality. They will identify, compare, and analyze attributes of two and three-dimensional shapes. Then they develop vocabulary to describe the attributes. They also use manipulatives to analyze the...

Learners complete word problems dealing with perimeter, area, length of sides, and more. They complete 10 multiple choice word problems.

Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...

In this different dice worksheet, 9th graders read about the use of octahedrons as dice, review the probability with cubical dice, then answer the question of probability when rolling 2 octahedral dice.

In this isosceles triangles worksheet, pupils justify and determine the symmetry of an isosceles triangle. They explore the bisector of rectangles. This three-page worksheet contains two problems. Answers are listed on page three.

Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.

Bring about the change you want to see in the world  or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to...

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

Your class will investigate the relationship among different triangles. This geometry instructional activity, demonstrates how to make a connection between triangles and the Pythagorean Theorem. They identify the missing side or angle of...

Learners investigate the process necessary to construct regular polygons. They explore the degree measures of the angles in a regular polygon. Using this information and technology in the form of Cabri Jr., your pupils will construct...

In this geometry lesson, 10th graders fold a dollar bill to make a tetrahedron. They analyze geometric shapes and apply it hands on.

Learners create a Hexaflexagon using a formula. In this calculus lesson, students apply the definition of delta epsilon as it relates to limit to create a shape using creases. They relate the same rule to triangles and investigate angles.

In this triangles worksheet, students solve six word problems where they determine the angles measures in different triangles.

For this writing algebraic equations worksheet, students write the equation and solve the given word problems. There are 14 perimeter and 12 coin problems. Answers are on the bottom of the pages.

In this perimeter worksheet, students calculate the perimeter of various different triangles. There are four problems to solve.

Tenth graders discuss the history of geometry as it relates to pentagons. For this geometry lesson, 10th graders solve problems of a pentagon inscribed inside of a circle using ratio. They review other properties for shapes of polygons...

Students use the inequality theorem to solve triangles and their properties. In this geometry activity, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

Learners create different angles and shapes by using different lengths of straws. In this geometry straws lesson plan, students glue straws onto paper and define what they have made.

Learners develop their awareness that straight line segments can produce the illusion of a curve and helps them recognize and describe number patterns and geometric fundamentals.
