Math Class on 2/12/07
Today in math class we started on multiplying fractions. But first we got our quizzes back that we did on Friday. Everyones test scores were good. Then we learned the formula so that we could multiply fractions. Here it is, a over b times c over d. In other words would multiply the numerators together and the denominators together. Here is an example, to do 3 over 5 times 2 over 3. First you would multiply 3 and 2 which equals 6, then multiply 5 and 3 which equals 15. So the fraction would be 6 over 15.Here is another hint when you multiply a whole number with a fraction you make the whole number a fraction. Here is an example, to love the problem 6 times 3 over 5 we make 6 a fraction by making it 6 over 1 so we still keep the same value. So we multiply 6 times 3 which equals 18 and 1 times 5 which equals 5 so that our answer is 18 over 5. Anyway after doing some examples on the board we worked on correcting any mistakes on our quiz, then finished our practice CMT packets we started on Friday, then finally did pages 140-141 in J1. So that is what we did today in math class today.
Try and figure this one out. Send me your answer as a comment. I will post the first 10 people who got the right answer.

Hello! I just surfed on into your blog. This is very good! Are you an elementary school student just writing this for fun? If so, that’s really wonderful, and I hope you continue to use your blog as a vehicle to grow and explore all these topics. Or are you by any chance a whole classroom? Please let me know, as right now, I’m thinking of how whole classrooms can use technology to “publish” their work on the internet.
Keep up the great work! I loved reading your posts!
(Oh, and the answer to the fraction problem is 3/8, I believe!)
