Justin's Blogging on Blogging in Blogger

What was the hardest thing about this unit?
For me, the hardest part was trying to divide the subs equally among the people. Most of my ideas were wrong by a small amount(like 0.2 or something) so they didn't work togther and i was confused.

What do you understand now that you did not understand before?
I know understand how to show fractions using a one hour clock. 1/2 an hour is 30 minutes 1/6 an hour is 10 minutes! I also learned how to find 3/4 of any number. Say you trying to find 3/4 of 24. First you cut 24 in half. That is 12. Then you cut 12 in half. That equals 6. After thta you add 12 and 6. 12+6=18. 18 is 3/4 of 24.

If you had to teach your parent something about fractions what would it be and how would you do it?
If I had to show my father something about fractions i would show him how to find which is bigger on a one hour clock. 1/2+1/4 or 5/12+2/6. First I would draw 2 circles (each representing 60 minutes) and cut it in half(1/2=30 minutes) and cut it another quarter(1/4=15 minutes). Then you should add them together, that equals 45 minutes. Next I would show the next fractions. Cut the clock into 12 equal peices and shade 5 in(5/12 is equal to 25 minutes) and then shade in four of the extra pieces (2/6=20 minutes) 25+20=45. So both fractions are equal.
