Decimals and Percents - Part One
In this lesson, students will change decimals into percents.
First, you will copy the worksheet so that each student will have one.
Then, you will explain to the students how to change decimals into percents.
To change decimals into percents, you move the decimal point two places to the right and add the percent sign. For example:
2.27 = 227% .75 = 75%
After that, you will pass out the worksheet so that students can work on them independently.
