Students take a field trip to a local park or beach to collect objects. They practice counting the objects and put them into categories according to type of shape like a cone, cylinder, etc... As an extension to the lesson students could...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

The students create patterns and repeat colors for unity. They explore organic shapes and demonstrate awareness of design principles and art elements. They then create 3-D paper relief from a 2-D surface and demonstrate the difference...

Eighth graders calculate surface area of 3-D shapes. In this geometry lesson, 8th graders analyze cubes and prisms by finding their area and surface area. They compare the data of these two shapes.

In this 3D figure activity, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.

In this geometry/shapes worksheet, students select the shape in a row that is similar to a shape that begins the row, 4 rows total.

Fourth graders investigate regular polygons. In this regular polygon instructional activity, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.

Students review vocabulary shape cards. They match oral words of shapes with flash cards then they make and label their own set of shape flash cards and then review with a classmate.

Geometers graph figure translations, find coordinates for transformed figures, and write rules to describe transformations presented. The 2-page activity contains 14 problems, with answer key attached.

Third graders are exposed to finding the area of polygons by decomposing figures and recomposing them into rectangles. This strategy allows children to expand on their prior knowledge of constructing shapes by rearranging parts into...

Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Finish the winter wonderland with your preschoolers. They trace pine trees and the tops of mountains to complete the snowy drawing. Have them color their paper and display the drawings during a winter unit!

Students identify physical characteristics of developing streams and infer changes in the landscape by creating a river model.

Now that geometers know how to solve for square units, can they solve for cubed units? Explore this concept as scholars examine four cubes to solve for volume in each. A detailed example explains this process, but you may consider asking...

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...

Trigonometry, art, and Valentine's Day come together in a creative activity about parametric equations. Learners calculate several equations before graphing them either by hand, on a graphic calculator, or Excel spreadsheet to curve...

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...

Challenge your class to identify, label, and draw a wide range of symmetries with this worksheet. In addition, learners name symmetrical shapes and compare them to alphabet letters. This worksheet asks class members to work with lines of...

Upper graders investigate how to find the surface area when using two-dimensional shapes. They conduct an investigation in groups while working sample problems given during class discussion with the teacher. They also review how to...

Lizards are amazing! After a lesson on reptiles, take a look at this set of instructions. You'll be able to guide your class in making a paper lizard sculpture that moves. This idea also includes variations on the paper technique used...

High schoolers study geometric figures. They use graph paper or Geometer's Sketchpad to construct and decorate geometric shapes, and also create a 3-D polygon using construction paper and a given template.

Students research the similarities and differences between stabiles and mobiles, and the physics principles embodied in each construction. They investigate different types of fish and their habitats, paying special attention to their...

Students brainstorm names of plane and solid geometric figures. Afterward, they explore the skyline of large cities and note their agricultural shapes. Using construction paper, students build 3-D geometric structures to create a skyline...
