Learners examine the 10 steps of the accounting cycle. The cycle begins with the analysis of source documents and ends with the post-closing trial balance and interpreting the financial information.

Learners identify types of activities in the Plan-Do-Check-Act Cycle and watch how the cycle works on the job.

Learners examine the three steps of a processor scan cycle.

In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.

Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.

Explore The Study Cycle – an approach that research and experience shows is the best and most efficient way to study

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

In this learning activity you'll plot GDP data on a graph and determine a phase of the business cycle.

In this animated object, learners examine the different phases of a cell's life.

In this interactive object, learners study animal estrous cycle lengths. They then test their knowledge in three exercises.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.

In this interactive lesson, learners study examples of nouns that can be counted and nouns that cannot. They then identify whether a word is a "count" or a "noncount" noun in a practice exercise.

Students review the spelling rules for adding a suffix to a base word. They practice changing the "y" to "i" for some of the words that end in "y."

In this interactive object, learners practice using the phrasal verbs "get on," "get over," "get away," "get down to," and "get away with."

Students practice adding some of the basic prefixes to words in the English language.

Students practice adding prefixes to a variety of words in the English language.

In this learning activity you'll review and practice using "they're," "there," and "their" correctly.

In this learning activity you'll practice entering the plural present, plural present perfect, past, and past perfect forms of verbs.

Learners add suffixes to base words to form new verbs in this interactive exercise.

Students add suffixes to base words to form nouns in this interactive lesson.
