Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the...

Let the resource take center stage in a lesson on population density. Scholars use provided historical data on the center of the US population to see how it shifted over time. They plot the data on a spreadsheet to look the speed of its...

Show your class that trigonometric functions have characteristics of their own. A resource explores the features of trigonometric functions. Learners then connect those concepts to inverse trigonometric functions and trigonometric...

Learn similarity through a transformations lens! Individuals examine the effects of transformations and analyze the properties of similarity, and conclude that any image that can be created through transformations is similar. The...

Individuals show what they know about the geometric representations of complex numbers and linearity. Seventeen questions challenge them to demonstrate their knowledge of moduli and operations with complex numbers. The assessment is...

Young scholars explore the solar system. In this planets lesson, students learn about the other planets in the solar system. They watch a video clip from National Geographic on the solar system, compare and contrast the planets and...

In this exploring pendulums learning exercise, students experiment with pendulums they make in the lab. They vary the length of the strings and the weights to observe the changes in the pendulum's amplitude and frequency. They answer 3...

In this geometric calculations of solar storms worksheet, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They use...

Students apply the properties of a right triangle. In this triangle activity, students describe and compare radians to degrees. They solve problems using the properties and ratios of a right triangle.

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

In this triangulation worksheet, students 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 engage in a lesson that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the importance of...

For this DC motor worksheet, the learner answers 3 open-ended questions pertaining to the design of a DC motor. The worksheet is printable and the answers are revealed online.

In this similar figures learning exercise, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a...

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

Students explore the concept of sine. For this sine lesson, students create a sine graph from tooth picks. Students create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put them...

In this tessellation worksheet, students draw tessellations using specified figures. This one page worksheet contains five multi-step problems.

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

In this angular size worksheet, students read about how astronomers determine the size of objects in the sky by using their angular size. Students are given equations that allow scientists to convert the angular size into kilometers....
