Math for Elementary Teachers 201
Today was the last day of the 201 class which means no more blogging for awhile. Although I am taking the second part of this class so I may be back. Not to sure if she is going to have us do this blog again but we will see. Looking back this class has taught me a lot and has made me more aware of what I have to work on if I want to be a successful elementary teacher and also thought about going into psychology because of this class too. haha well here is a cute comic to end this course of blogging hope all did well on the exam today! :)
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.

Equality of fractions
The equality of fractions can be illustrated with sets of objects and compared.
an example of illustration in achieving a problem:
1/2 = 2/4
1/2 = 2/4
2/3 = 4/6
First draw out your fraction models draw out 3/3 and then right under that draw 6/6. Once you have drawn those models out color in 2 of the 1/3 pieces and 4 of the 1/6 pieces. Do those look equal to you? well that is because they are! You have completed an equaltiy problem. to check your illustration of the equation just check it with the drawing below.
for more practice on fraction equality you can go to the following website by clicking the on the word fraction.
