Sixth Grade
Today, the class learned how to order and compare fractions. To compare fractions, you first need to check to see if the denominators are the same. You can't compare them if the denominators are different. If they are the same, then you just compare the tops. If they are different, find a least common multiple and change one or both of the fractions (just like you do if you were going to add them together) and then you can compare the tops. For example:
2/3 compared with 5/6
Since the denominators are different, I need to find a least common denominator. That would be 6, so I just need to change 2/3. It would change to 4/6. Since 5 is bigger than 4, 5/6 is bigger than 2/3.
To order fractions from least to greatest, you also need to have common denominators. So if the denominators are different, make equivalent fractions and then you can order them by the numerators.
Seventh Grade
To find the percent decrease, remember that you divide the amount of decrease by the original amount. So if you are going to find the percent decrease of 62 to 45, you would first subtract the numbers to find the amount it decreased. 62 - 45 = 17. Then divide 17 by 62. You would put the 17 in the box:
Add a decimal point and three zeros. Remember, you add the three zeros in case you need to round to the hundredth (nearest percent). Move the decimal point up and start dividing. In the above example, after dividing to three places, the answer was .274 - so I looked at the 4 to see if the 7 would go up or stay the same. Since 4 is less than 5, it makes the 7 stay the same. So, that makes .27 and then you move the decimal point two places to the right to make a percent. The percent decrease is 27%.You are only doing 2-12.
Geography - You need to start researching the information for your states project. On Monday, you will be working on the backgrounds during Art class and the 3-D sculptures/designs during Geography class.

Pre-Algebra:
Translations. You all did a terrific job on these today! Email me if you have any questions.
Algebra I:
Systems of Equations - Substitution. Here is a link to a blog post from last year. The video shows you how to solve using substitution. Let me know if you have any questions!
See you tomorrow,
