How do I figure out my grade?

Converting percents to decimalsWhen I grade Math 112 tests I often write the raw score as a fraction.  For example, on Test #1 the total number of points possible was 18.  If you got 13 out of 18 how do you figure out the percent?  Here's how you do it!  Just divide the denominator (18) into the numerator (13) and round the answer to the nearest hundredth.  Then change the answer to a percent. 

So, for our example:  13 divided by 18 is .72222222. . . .   To round to the nearest hundredth you look at the number in the thousandths place (the third number after the decimal), which is 2.  Since this is not 5 or larger you do not round the number in the hundreds place up.  So .722222 . . . . is .72 to the nearest hundredths.

Now we have to change this to a percent - but that's not hard!  Just put 72 over 100 and you can see the score is 72%!

If you show me how to change YOUR raw score into a percentage by writing it out on a separate sheet of paper I will give you 2 extra credit points.  But don't tell anyone!  This offer is only for students who read this blog!!!!!  So how will I know if you read my blog?  You have to leave a comment here!  If you do those 2 things (show work and leave a comment) then I'll give you the extra credit points!!!!!  :)  Have a good day!

How you can practice basic skills!

Greetings!

I'm in a training at Los Angeles County Office of Education and we're learning how to create blogs. I'm not quite sure how I'm going to use this for our class, but I think it will be fun to try it out and see if it's useful for our class.    

I found one cool website to help you practice times tables in a fun way!  You can practice twos through fifteens or mixed numbers.  They give you 8 problems at a time, you pick the correct multiple choice answer and submit, and each time you try it you'll get different numbers.  If you need practice with your times tables it is a fun way to practice.

Here it is: http://www.mathsisfun.com/timestable.html

I also found a fun way to practice fractions playing different games - soccer math games, millionaire math games, baseball math games, and on and on.  Try it and let me know if you like it!
