Lesson #2 - Changing Percents to Decimals This tutorial centers on dividing by 100, and provides many examples of changing percents to decimals. Includes working with percents that are less than 1% as well as percents that are greater than 100%.
Lesson #4 - Changing Percents to Fractions and Mixed Numbers. Tutorial gives many examples of writing the fractional and mixed number equivalences of percents. Offers option to review common factor, and before entering the concept check section, presents option to review proper, improper fractions, and changing a mixed number to an improper fraction.
Lesson #5 - Changing Fractions to Percents Tutorial with functional graphics offers many examples of this basic skill. Because the technique of changing decimals to percents is a needed skill in changing fractions to percents, the tutorial has several options for review before the student enters the concept check. Item analysis in the concept check focuses on changing proper fractions to percents, changing mixed numbers to percents, and changing improper fractions to percents. A part of the tutorial reviews dividing the numerator by the denominator in problems with a remainder of more than two decimal places.
Lesson #6 - Finding a Percent of a Number Tutorial with graphics and concept checks offers many examples and poses writing the percent as a decimal as well as a fraction, and then multiplying. The lesson covers multiple discounts and many daily applications of finding percents. It offers options to review prerequisite skills. Item analysis gives student performance on percents less than 1, from 1 to 99, and 100 and greater. Graphics show the difference between the decimal equivalent of a fraction and the decimal equivalent of a fractional percent in the context of the multiplier used to find a percent.
Lesson #7 - Finding the Percent One Number Is to Another Number Tutorial with graphics and concept checks offers many examples and applications of the basic method of dividing the part by the whole. It offers options to review the prerequisite skills of changing fractions and decimals to percents. Item analysis gives student performance on percents less than 1, from 1 to 99, and 100 and greater. Problems stress finding the question asked by careful examination of the language of the problem.
Lesson #8 - Finding the Percent of a Change -- an Increase or a Decrease Tutorial explains the basic method of finding the percent of a change, gives many examples, and applies the basic method to problem solving. It offers options to review the prerequisite skills of changing fractions and decimals to percents. Scrutiny of what the question asks is emphasized in working the problems.
Lesson #9 - How to Find a Number When the Percent Is Known Tutorial explains the basic method of dividing the part by the percent known. It also covers the algebraic method of solving for "n." Includes option to review the prerequisite skill of changing percents to decimals.
Lesson #10 - Review of Mixed Problems on Finding Percents Problems used are from Lessons 6-9. Twelve questions are asked randomly from a bank of sixty-two questions. Incorrect responses are followed immediately by complete explanations of the correct solution. Option to improve score by redoing another quiz is presented if the score is less than 100%.
