Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

In this polygon worksheet, students identify and create a six-pointed star by completing 6 steps. First, they use a compass to trace a circle with a given radius. Then, students draw a point on circumference of the circle and place the...

In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Test your scholars' knowledge of a multitude of concepts with an assessment aligned to the California math standards. Using the exam, class members show what they know about the four operations, positive and negative numbers, statistics...

Fourth graders investigate congruent shapes. In this congruency lesson, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

Students describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Ninth graders play guess my shape (either describe or use a feely bag to introduce the 3 shapes in the problem.) As they are identified put them in an order as shown in the problem. As the students work on the problem in pairs teacher...

Students identify polygons. In this geometric shapes lesson plan, students identify and describe polygons. Students create new shapes out of the shapes they are given.

Learners use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...

Students identify and create shapes. In this geometric shapes instructional activity, students identify various polygons and try to create new shapes using existing polygons.

Students listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.

Ninth graders experiment with paper folding to create geometrical shapes. Students analyze the Copymaster of the problem. After the students have worked on their own for a while, stop them and discuss.

Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...

In this symmetry worksheet, students select the shape from a choice of 4 that is not symmetrical, 4 problems total. Answers included on page 2.

Students explore geometry in Navajo rugs. In this shape art instructional activity, students create a Navajo rug design using triangles and squares. Students investigate designs on the Internet and then create an original design.

Students identify the shapes of different polygons. In this geometry lesson, students identify the same area and perimeter in shapes. They use the correct formula for the correct shape.

For this geometry worksheet, students solve 4 problems in which a given geometric shape is recognized and circled in a group of shapes. Students cross out the shape in each set that is not like the others.

Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.

Seventh graders measure surface area. In this geometry instructional activity, 7th graders find the surface area of various geometrical shapes. Using a computer program, students compute the area of 2-D and 3-D...

Fourth graders examine faces, edges, and vertices. In this geometry lesson, 4th graders participate in classroom activities that require them to compare geometric shapes, figures, and models.

Students sketch cones and identify its properties. In this geometry instructional activity, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.
