Seventh Grade
ITBS tests are this week and we spent most of the morning taking some of the tests. Homework will be minimal, but the class will still have Spelling and Vocabulary. Spelling unit 8 is due on Friday. Tomorrow, we will discuss the new vocabulary words. The unit isn't due until next Wednesday.
Remember to get plenty of sleep and eat breakfast! Bring a healthy snack too. Your brain needs energy to do well on the tests!
Eighth Grade
Lesson 2-2 #26-44 ALL.
Dividing scientific notation.
To divide in scientific notation, first, divide the first numbers. You can use a calculator to do this. Then, to divide the powers of 10, subtract the top exponent minus the bottom exponent. Then, check to make sure that the answer is in scientific notation. For example:
The first step is to divide 3.5 by 7. That is 0.5.
Then, subtract the exponents: 5 - (-3) = 5 + (+3) = 8
Next, check to see if the answer is in scientific notation. Since there is only a zero before the decimal, you need to move the decimal one place to the right. Because you are moving to the right, you add a negative 1 to the exponent. So 8 + (-1) = 7.
See you tomorrow!
