Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

This activity is a follow-on activity to inscribing a square in a circle. The overall problem is more complex. It deals with geometric constructions, properties of triangles, and regular hexagons. The final part of the activity...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

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.

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.

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...

Learners are posted at the beginning and end of a 10-meter long line parallel to the ocean and are instructed to look straight ahead towards the water. The student at the beginning of the line uses a stopwatch, goes to the water's edge...

In this AC phase worksheet, students answer 24 questions about AC and DC voltages, phasor diagrams, sine wave graphs and Lissajous figures.

Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Students inspect the causes and effects of earthquakes and examine how seismic waves travel. For this earthquake lesson, students determine where earthquakes happen and why, before determining how to build an earthquake resistant...
