Young scholars investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Students explore the relationship of angles as it relates to 2 and 3-D shapes. In this geometry lesson, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They manipulate a math...

Investigate polygons from rectangles to triangles to octagons. Each level of the five-problem series targets a different grade level. Beginning with the level A problem, learners examine the relationship between area and perimeter by...

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

Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.

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

Young scholars 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.

Third graders create 2D and 3D shapes using marshmallows and toothpicks. In this geometry lesson, 3rd graders create their shapes and document the number of faces, edges, corners, angles, and sides. They share one shape and its...

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

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Fifth graders explore geometry by creating shapes with construction paper. In this shape characteristics lesson plan, 5th graders identify the different attributes that make up specific shapes and create them using construction paper,...

Students identify symmetry in shapes. In this geometry lesson, students fold paper to identify lines of symmetry. Students create various symmetrical shapes using folded paper.

Tenth graders investigate the history of geometry and its different shapes. For this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

In this interactive lesson, 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 tessellations. They...

Sixth graders create polygons. In this shapes lesson, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.

Not all structures take the shape of a polygon. The 21st lesson in a series of 29 shows young mathematicians they can create polygons out of composite shapes. Once they deconstruct the structures, they find the area of the composite figure.

How do you know you know? Prove it! The guide goes through several examples and includes a link to a video to teach learners how to work through coordinate proofs. The goal is to prove that different shapes are indeed that shape. 

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...

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. 

Students identify polygons.  In this polygon people lesson, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The lesson may be extended by allowing students...

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...

Students explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Students collaborate in graphing additional functions.

Learners 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.
