In this triangles activity, students identify 3 triangles by the length of their sides and 3 triangles according to their internal angles.

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Students investigate the Pythagorean Theorem. In this geometry lesson, students define angles and sides of right triangles. They calculate the area and surface area using formulas derived by the Pythagorean Theorem.

Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle lesson plan, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...

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

Students study polygons. In this math lesson plan, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.

Students explore geometry by drawing various shapes in class. In this triangle characteristics lesson, students identify the attributes that classify a shape as a triangle and practice using their bodies to create triangles in class....

Fifth graders participate in a review game of geometry topics. In this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...

Students classify different types of triangles. In this geometry lesson, students identify and use properties of triangles. They differentiate between isosceles and equilateral triangles.

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

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...

In this polygon worksheet, students observe pictures of polygons and identify their proper name. They read descriptions of polygons and determine the polygon described. This one-page worksheet contains ten problems.

Tenth graders investigate where in the real world triangles are used. In this geometry lesson, 10th graders write an essay describing where in their lives triangles are used. They can use food, buildings, clothing or anything triangular...

Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...

In this geometry learning exercise, 10th graders examine the special segments that occur in a triangle.  The three page learning exercise contains twenty-five problems.  Answers are not included. 

Learners identify the pattern in a problem. In this geometry instructional activity, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.

Young scholars are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...

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

Learners participate in a number of hands-on shape-related activities. They match and sort shapes by attribute, read books about shapes, complete shape art projects and explore and compare parts of shapes.

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Learners identity simple geometric shapes. In this early geometry lesson, the teacher introduces students to triangles, squares, and rectangles, then learners identify and classify the shapes as they are found in the classroom. To...

Students identify, compare and classify the various shapes. In this shapes instructional activity, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher...

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...
