Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related lesson is Coordinate Grid: Mapping an Archeological Site.

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...

Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Middle schoolers measure the angles of a milk carton. They identify and label acute, right, and obtuse angles. Using appropriate tools, students determine the volume of a cube or a rectangular prism. Middle schoolers complete...

Students investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

In this Archimedes worksheet, students complete and respond to 4 different problems related to different triangles. First, they find the midpoint of each side of a given triangle. Then, students connect the midpoints with the opposite...

This task asks learners to prove that the segment joining the midpoints of two sides of a parallelogram is both congruent and parallel to an adjacent side of the parallelogram. The activity would be good to use in a discussion about how...

Shapes are all around us! Kindergartenrs identify shapes in their world and guess the shape being described. They participate in a shape hunt.

Let's study 2-D shapes! Young mathematicians compare and classify shapes according to attributes. They evaluate shape riddles and predict the shape being described. Here is the website where you can find the...

A six-page packet walks, or bends learners through angles that combine to create triangles. Definitions are given for right triangles, obtuse and acute triangles. They draw angles according to directions, using a protractor to meet the...

In this Aurora Borealis worksheet, students read about how early scientists used triangulation to measure the height of the Aurora Borealis. Students solve 3 problems using triangulation.

High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...

In this triangulation worksheet, learners solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...

Students explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles,...

Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Students create a silhouette by directing light at a person. They change the light, distance from the person and angle to make the shadows different. They are to describe the relationship between the light source and the object.

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

Students create different shapes by putting light on different objects. They change the distance from the object, the light source and angles to make the shadows different. They are to describe the relationship between the light, object...

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

Students calculate the tangent ratio given a right triangle. In this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.

Students identify and analyze how levers work by raising a brick with a shish kebab skewer. Students present their work, explaining what did and did not work, including illustrations of the lever lift from different angles. Students...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.
