Learners follow step-by-step instructions for dividing algebraic fractions. They begin by reducing the fractions to their simplest form. Immediate feedback is provided. This activity has audio content.

In this animated and interactive object, learners view two examples of how to subtract fractions with unlike denominators and then work five similar problems.

In this learning activity you'll identify fractions and view illustrations of fractions.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

In this learning activity you'll demonstrate how to use unity fractions to complete conversion calculations.

Learners examine how metal detectors function. This object includes animation and sound.

In this learning activity you'll perform subtraction calculations using borrowing with mixed number fractions.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

Every speech starts with an outline. Knowing how to write one can make the difference between speech success and speech failure. In this module, we’ll explore what’s involved in creating an outline, demonstrate how to put one together, and give you examples you can use to create your own outline.

In this learning activity you'll play "How to Really Be a Millionaire" to learn the basics of accumulating wealth.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

The learner will understand how to properly use a fillet gage to measure weld size.

In this highly interactive and animated object, learners follow a step-by-step process to reduce algebraic fractions, which contain no addition or subtraction, to their simplest, most elementary form. Immediate feedback is provided. This activity has audio content.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

In this interactive and animated object, learners follow instructions for finding the lowest common denominator for a group of algebraic fractions. Immediate feedback is provided. This activity has audio content.

In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions so that they can then be multiplied. This activity has audio content.

In this learning activity you'll discover what C.R.U.D. applications are and how they're used in everyday life.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.
