Pupils identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Pupils then...

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

Students culminate a unit on measurement with a focus on area and perimeter. They design a floor plan of their dream room on graph paper showing the proper area and perimeter. They plan the budget for their room and make a 3-D scale...

Third graders explore the attributes of polygons. In this geometric shapes instructional activity, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons....

Learners read "Captain Invincible and the Space Shapes" by Stuart Murphy and view a PowerPoint presentation on shapes. They identify shapes presented in the book and then identify shapes found in their classroom.

Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.

Students explore pyramids. In this math lesson, students discuss where they have seen examples of pyramids. Students classify pyramids as three-dimensional figures and identify their attributes.

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.

Quadratic solutions come in all shapes and sizes, so help your classes find the right one! Learners use the quadratic formula to find solutions for quadratic equations. Solutions vary from one, two, and complex. 

Develop an understanding of algebraic sequences through an exploration of patterns. Five leveled problems target grade levels from elementary through high school. Each problem asks young mathematicians to recognize a geometric pattern....

Help your classes find the significance in this lesson! Learners analyze the probability of Diff values. They then determine if the difference is significant based on their probability of occurrence. 

Students establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Students identify and match pictures of three dimensional shapes while playing a board game with peers. They take turns with their partners in spinning the spinner and moving to the next space on the game board that shows the same shape.

First graders identify geometric solids. In this shapes and solids beginning geometry lesson, 1st graders reach into a bag and identify the geometric solid they feel. Students describe shape attributes and match two dimensional shapes to...

Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.

Third graders incorporate math into dancing. In this algebra lesson plan, 3rd graders identify different shapes and patterns using dance movements. They relate the different creations to polygons as they incorporate the use of stretchy...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Have your class practice measuring the perimeter of various objects using this resource. Fifth graders place various-sized polygons in order (from largest to smallest). They use non-standard measuring tools to estimate the distance...

In this interactive instructional activity, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create...

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.
