Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Students explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Don't worry if you do not have the mentioned textbook; there is enough material here for you to carry out a pertinent polygon plan. After introducing your class to various polygons and the prefixes that help identify them, hand out...

Students identify solid figures. In this classification lesson, students recognize and name solid figures. Students identify which figures contain polygons and rectangles. Students practice counting vertices, faces and edges.

Students identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on each figure.

Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

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...

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

An outstanding instructional activity on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about...

Students cut out three different shapes and put them in the correct categories of parallelograms, trapezoids, and trapeziums. In this parallelogram lesson plan, students explain the sums of the angles of a triangle and a quadrilateral.

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Students classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Students identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Students use a dictionary to gather appropriate information for writing simple definitions. They recognize prefixes that relate to numbers, such as mono-, bi-, and tri-. Pupils use their creative abilities to extrapolate new words to...

Students investigate measurement through the use of literature through this series of lessons.

Fifth graders use estimation to solve word problems. In this fractions lesson, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This lesson...

Students 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 importance of...

Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.
