Students classify, flip, slide, and turn a quantity of quadrilaterals.

Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Students experience how to illustrate some of the many connections between number and geometry. Through this 2-3 day focus on square numbers and triangular numbers, students make connections among mathematical topics.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Fourth graders identify and label different types of polygons in real life situations. Using a digital camera, they take pictures of polygons on the school grounds, tally the number of shapes found, and answer discussion questions.

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...

Students model and solve a real-world problem by constructing the centroid of a triangle. They explore relationships of the medians of a triangle and investigate how the centroid partitions each of the medians. Students investigate...

High schoolers 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...

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...

Learners compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

In this math worksheet, students analyze 15 pictures of geometric figures and match them to the names which are provided in a word bank. Students tell how many lines of symmetry each shape has.

In this transformations and congruence worksheet, 10th graders solve and complete 5 different types of problems. First, they calculate the length of a line giving their answer in 3 significant figures. Then, students prove that two...

In this shapes activity, students identify and name 6 different shapes by utilizing a binary tree (flow chart) to answer questions and guide them to their appropriate answers.

In this perimeter worksheet, students find the perimeter of given regular and irregular polygons. This four-page worksheet contains 20 problems. This interactive worksheet may be completed online or printed for paper use.

In this tessellations worksheet, students solve 2 word problems where they use the "make a pattern strategy" to form tessellations from geometric shapes. There is scaffolding for the problem solving strategy.

In this congruent triangles and rectangles worksheet, students solve 6 word problems where they identify whether triangles and rectangles are congruent, and construct triangles. Students must explain their reasoning and prove each answer.

In this similar figure worksheet, students use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page worksheet contains 8...

In this area and perimeter worksheet, learners are given the equations to find the perimeter and area of objects. They practice finding the perimeter by measuring the sides of given objects and adding them together. They find the area of...

Young scholars construct two dimensional models to illustrate squared numbers. For this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Young scholars identify powers and relationships between...

In this transformations worksheet, high schoolers solve 25 short answer problems.  Students dilate, reflect, and translate points and figures in the coordinate plane.  High schoolers determine scale factors and lines of...
