Today we had a quiz on changing percents to fractions and back again. We went on to learn how to convert percents to decimals and back. Students understand that a percent can be made into a fraction and then written as a decimal but then they were shown the 'trick'. Thinking about the alphabet...we now that to go from a'D' (for decimal) to a 'P' for percent, you travel to the right. So going from a 'P' to a 'D', you travel to the left. Therefore, when you convert a decimal like .34 to a percent, you move the decimal point 2 places, (always 2) to the right and your answer is 34%. Likewise, if you are converting a percent such as 9% to a decimal, you move the decimal point 2 places to the left such = .09 [we assume the decimal is after the whole number unless there is one present]. Tonight's homework reviews fractions and percents as well as decimals. Homework is in the workbook [8-4] Practice 1-5 and 11-16 AND [8-5] Study Guide 1-16.
