Fifth graders solve problems while examining a variety of isosceles triangles.  In this isosceles triangle instructional activity, 5th graders examine shapes to find their characteristics.  Students pay particular attention to...

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.

Fourth graders explore geometric properties and relationships in a two-dimensional work of art. They first search for and identify polygons in a Cubist painting and then use polygons to create their own Cubist portrait of a classmate.

Students collect microscopic images from a variety of chemical specimens to determine the identity of a mystery powder. They use a ProScope Digital USB Microscope to describe and compare the crystal size and shape of the chemicals.

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Students randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.

Students interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...

Fourth graders examine nature paintings from a Utah museum for their physical characteristics. In small groups, they observe museum postcards and discuss the season, precipitation, temperature, and geometric shapes pictured. Focusing...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional shapes...

Second graders calculate mileage for a journey. In this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the...

Students describe techniques helpful in solving spatial problems which utilize the notion that a model is a simplified version of something complicated. They utilize methods such as sketching or drawing possible solutions to a problem.

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

Third graders create a butterfly drawing that includes the elements of art and principles of design. They create artwork that can be made into ceramic tiles to be installed around the classroom doorways in our new addition.

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...

Pupils investigate segments in a triangle by constructing a triangle using Cabri Jr. They construct segments within the triangle that lie on the midpoints of the triangle's sides. Learners then compare the slope of base of the triangle...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...
