Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

What caused the extra rotation? Class members visualize a coin rolling around the circumference of another coin. They determine the reason the rolling coin rotates twice. Further questions require them to determine a generalized formula...

It's probably a good idea to use the unit. Young mathematicians learn about conditional probability using Venn diagrams, tree diagrams, and two-way tables. They also take into consideration independence and the addition rules.

The team at Periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about krypton- element number 36 in the periodic table and the fourth noble gas. [1:10]
