Lesson 

· Remind students that fractions, decimals and percents are all different ways to represent the same thing. · Percents can be written as decimals by dividing by 100. This is the same thing as moving the decimal two times to the left. · Students will write percents as decimals · Walk through reasoning before teaching students how to calculate percent of a number. · If the percent is between 0 and 99 then you are going to have an end result that is less than the number · Use the benchmark of 50% to estimate about what your number should be. · Walk through the procedure to calculating percents of a number. · First turn the percent into a decimal · Then write the equation of multiplying the decimal by number. · Check the answer to make sure it makes sense. ·
