Fun with Fractions and Percents!

A fraction can be showed as a percent by converting the fraction to a decimal number.Then multiplying the number by 100 to get the percentage. Percent means it is out of a hundred.
                                                                   1/4= .25=25%

                                             one fourth
Another trick to converting a decimal to percent is moving the decimal point behind the hundredths place to the right. Like shown in this video.


When at the end of teaching converting fractions to percentages you can try playing BINGO if you know your class can handle this type of activity in a disciplined manner. I remember playing this game in middle school, Just create different BINGO sheets of fractions and percents then make matching cards in the opposite form as fraction or percent). You will call out what is on the card and you may show it so they can have a visual also then they can mark their cards as you go along. I found a game like I explained with just decimals included at the following link. BINGO game.
