Accelerated Pre-Algebra (10-11) A peek inside our classroom. This is an interactive learning community for students and parents of my 7th Grade Accelerated Pre-Algebra class for the school year 2010/2011. The discussion and information will be as meaningful as you make it.

Today in math class we talking about what we had to do for homework because everyone didn't know what to do for homework from the substitute. We had to make wumps like mug, zug, lug,bug, and glug. Then we copied down are homework. We started to see who was the imposter's from mug the wump. Then started to wrap up 2.1 by starting the wumps hats. we compared them to mugs hat that they all ready gave to us. Then we plotted the table for the graphs. We graphed them and then Ms Favazza handed out are test from last week with the GCF, LCM, fractions and decimals. Ms Favazza wasn't feeling good still so she couldn't yell at us as mush as she wanted to. ha ha. We started to learn the corresponding angle and corresponding sides in a shape. corresponding angles means if you make a shape bigger and compare it to the original one some sides and angles are the same the size is the only one that changes. Fun math class today.

Math class 12/1/10
The major topic of todays math class was multiplying and divideing fractions. When you multiply fractions you take the top row of the fraction to get an answer then do the same to the bottom. If the number is a mixed number you change it to a improper fraction.
4 1/2 * 2/6 = 9/2 * 2/6. So you multiply the top row of numbers 2 * 9 =18. Or if a number on the top can be divided be a number and a number on the bottom can be divided by the same number you can divide them. So cross out the 2s to 1 because 2/2 = 1. Also 9/3 = 3 and 6/3 = 2. so replace the numbers 3/1 * 1/2 = 3/2 this is alot easier. Then you have to try to simplify 3/2 = 1 1/2.
Division is very similar because you switch the place of the top and bottom number in ONLY the sencond number. So if the number problem is 10/6 divided by 1/2 you switch 1/2 to 2/1 then multiply. These are the basics of multiplying and divideing fractions but remember the rules of negatives, one negative the number is negative, and two negatives the number is positive. Just in case something like -1/2 * 9/7 happens.
