Yesterday in class we looked at changing a fraction into a decimal, then changing that decimal to a percent. Students took notes on the steps necessary to do these conversions, then we practiced a couple of eog type examples. Students should be writing these examples in their notes or on the back of their outline. At the end of class, I gave a survey to each class to gather some data for todays assignment.
Today, students will be given a copy of the survey results and figure out what percent of the class chose each answer. I will allow them to work in pairs unless behavior becomes a problem.
Below are the steps we used to convert from fractions to decimals and decimals to percents
Fraction to decimal
-Convert mixed numbers or whole numbers to improper fractions and simplify if possible
-Divide numerator by denominator
Decimal to Percent %
Move decimal 2 places to the right
Add % symbol on the end
Percent to decimal
Move decimal 2 places to the left
Drop % symbol
