Examine the process of rotating images to visualize effects of changes to them. The fifth lesson of 18 prompts pupils to rotate different images to various degrees of rotation. It pays special attention to rotations in multiples of 90...

Design the best from the best. Groups work together to come up with the best configuration of different variables that affect a wind turbine. The teams choose from several variables such as the number of blades, the angle of the blades,...

Challenge scholars to show what they know about properties and addition and subtraction formulas for trigonometric functions. The resource provides a mid-unit check on the progress toward mastery of trigonometric concepts. The areas...

Two videos show first how to perform a rotation, given the center, the angle, and the direction of rotations. Individuals then see how to find what the rotation is from one figure to another. Pupils practice doing both in seven problems...

The universe is full of sources of energy. Explore the energy of pulsars with your classes through a simulation. An interactive lesson allows learners to manipulate the angle of rotation of both the earth and the pulsars. A real-time...

In this, the third in a series of four resources that use Robert Wise's 1951 version of The Day The Earth Stood Still as the core text, young film makers examine the language of film including shot composition, camera angle, lighting,...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based instructional activity includes a range of learning experiences, from experimenting with the rate at...

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

Is there a relationship between the sign of sine and cosine and the angle on the unit circle? Scholars use an interactive to see the value of sine and cosine within different quadrants. they then use the information to determine the...

It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...

Does complex number multiplication have the class spinning? Here's a resource that helps pupils explore and discover the geometric effect of multiplying complex numbers. In the 14th installment in the 32-part unit groups look at the unit...

What was the property again? Tired of hearing this from your pupils? Use this table to organize properties studied and as a reference tool for individuals. Learners apply each property in the third column of the table to ensure their...

In this angles instructional activity, students estimate angles to within 15 degrees, then measure and name each. A reference web site is given for additional activities.

Learners are given one angle measurement and determine either the corresponding supplementary or complementary angle measurement. A reference web site is given for additional activities.

Mermaids will sing to your class members as they engage in an activity related to T.S. Eliot's famous dramatic interior monologue. After engaging in a socratic seminar about literary devices in the poem, individuals choose one...

Learners examine a figure made up of different types of triangles and then determine whether each triangle is right, acute, or obtuse. Next, they color each type of triangle a different color. Finally, pupils answer three fill in the...

Students use prior knowledge of angle and lines as they conduct an experiment with a rolling marble to determine the shape of a mystery object located under a metal pie tin.
