Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Students examine functions and function notation. They use computer activities to discover how to graph functions, and conduct a vertical line test. Students describe spatial relationships using coordinate geometry.

Students explore symmetry.  For this geometry and scientific inquiry lesson, students design paper airplanes with middle line symmetry, as well as right, obtuse, and acute angles.  Students measure the plane's angles using a...

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

Sixth graders view a video of tessellating an egg shape. They focus upon the problem solving strategies used and how tessellation geometry was used to construct the three dimensional figure. They create their own tiling patterns.

In this geometry worksheet, 10th graders investigate and solve various logic problems including the constructions and use of two way tables and Venn diagrams to assist in problem solving.  The eleven page worksheet contains nine...

Tenth graders explore congruent triangles.  In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson combines dry erase board activities and the use of technology.

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Tenth graders perform reflections on different geometric shapes. In this geometry worksheet,students define the concept of geometric reflections and find the coordinates of the reflection on a coordinate grid.

Students perform transformation on their polygons. In this geometry lesson, students identify the correct transformation of each shape. They move the polygons around on a coordinate plane. There are extension and homework activities...

Tenth graders explore and define the radius and diameter of a circle. In this geometry lesson, 10th graders calculate the circumference and area of a circle using real world objects and shapes. They discuss chords and lines tangent...

Students explore symmetry. In this geometry lesson, student identify and define bilateral symmetry, radial symmetry, pentagonal symmetry, hexagonal symmetry, and cubic symmetry. Students construct examples of these types of symmetry and...

Bring out the inner artist with this Abraham Lincoln lesson plan. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...

How similar do figures have to be to be similar figures? Individuals learn to identify similar figures by verifying that angles are congruent and sides are proportional. Additionally, they match the corresponding parts of similar figures.

After learning that the sum of interior angles for triangles is 108 degrees, take it further to show that the sum of angles in any polygon is the same! Using hexagons, pupils practice finding the measure of the six congruent angles. Make...

Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They calculate the volume, area and perimeters of the shapes created on a coordinate plane.

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...

In this geometry instructional activity, 10th graders are given polygons on a coordinate plane. They calculate the area and perimeter of each shape, by counting the length of each square on the graph.

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Learners find out the meaning for prefixes used in math vocabulary. By dissecting words used in everyday math, they figure out what the prefix indicates and what the word means. A variety of well-organized worksheets and activities...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...
