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....

Junior geometers practice stating the names of different geometric shapes. They define and name the different shapes and compare and contrast shapes to one another. They also relate the shapes to objects in the real world.

Print these shapes on cardstock, laminate them, cut them out, and use them to teach kindergarten and first graders about the attributes of shapes. 

Shape shifters examine and experiment with pattern shapes.  In this geometry instructional activity, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed...

Third graders participate in a variety of hands-on activities that involve the effects of force on an object: What a Load, Over the Edge, Collision Zone, and Straw Rocket. They practice describing and comparing attributes of...

Sixth graders investigate the geometric concept of shapes. They locate shapes in their immediate environment and label them according to basic shape. The shapes that are found are recorded by the teacher on chart paper and any...

Through the use of Internet, video, and hands-on activities, youngsters learn the parts and characteristics of a circle. This fantastic lesson has some excellent website activities included in the plan. Your kids will have a much greater...

Students explore the concept of equivalence as it relates to comparing concrete objects to determine greater or lesser attributes such as length and weight. In this pan balance-shapes lesson plan, students make estimations while...

This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

Fifth graders sit in a circle and are given geometric attributes, i.e. four equal sides, etc. They run around the circle when a shape is called that corrolates to their attributes. They try to tag other students also running around the...

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.

Students 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.

Sixth graders read and discuss information regarding the shape and attributes of an eggshell. For this shape of things lesson, 6th graders gather relevant information that pertains to the incubation and formation of an eggshell. ...

Sort this resource into the Use pile. Scholars investigate attributes of quadrilaterals and then use the results to sort and classify the shapes labeling each figure with their properties to justify the classifications.

Linear measurement is the focus of this math lesson. Youngsters work in groups to build towers with blocks. They build towers represented on index cards and determine how many blocks taller one tower is.

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...

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...

What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Although learners don't need to identify numbers as even or odd here, they do match each to a set of shapes. There are six numbers written numerically along with either odd or even. Scholars match each to a set of shapes with...

Students classify various hardware items using the attributes of the objects. In this classification lesson, students group objects based on their attributes and explain their classification key.

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...

Fourth graders use polygons to create animal figures with symmetry. In this polygons and symmetry lesson, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math activities.
