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...

Systematically combine shapes to arrive at one solution. The resource models a system of linear equations using colored shapes. Pupils follow rules to combine circles and squares to add the two equations together, resulting in one...

In this geometry skills instructional activity, students examine a graph and respond to 5 questions that require them to identify the coordinate pairs of object on the grid.

In this lower elementary geometry instructional activity, students make a shape book. They receive a book with the outline of a circle, triangle, square, and rectangle with the word that names the shape. They cut out images of the four...

High schoolers analyze relationship between the increase in polygons sides and a circle. In this geometry lesson, students relate the size of the central angle of a polygon, to a circle. They compare the formula for the area of a polygon...

Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Young scholars explore tessellations. They are shown a selection of shapes. Students identify shapes that tessellate and justify their answer. Young scholars create their own tessellation.

Students observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

After walking in a nearby neighborhood, have your class create this amazing city street pop-up. They study the facades of the buildings they see, focusing on geometric line, shape, and architecture. They then draw, cut, and create a city...

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...

Young scholars recognize things that are the same and things that are different. They use shape, size, numbers and color, for recognition. They make fish with different shapes/colors on them and 'fish' for the kind of fish that displays...

Youngsters add some shapes to this castle drawing before analyzing its geometry. They count the circles, triangles, rectangles, and squares. The objectives here include drawing, recognizing, and counting shapes as well as writing numbers...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Lower elementary learners recognize solid shapes distributed for making fractions. Each individual uses a wheel and determine which part of a fraction is missing. This is a great instructional activity for your visual learners!

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this instructional activity to...

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....

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.

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 create a picture of an actual scene or overlap the called out lines or shapes into a space-breaker. If someone calls out a line or shape a student had not planned to use in the art, they have to figure out some way to use it...

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...

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

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.
