SIXTH GRADE

Today, the class practiced some more with adding and subtracting decimals. On the assignment, do #1-22 and 27-30 only. Please use a separate sheet of paper for at least #11-22 and #27-30. Parents, just so you know the class is settling down and worked much better today! They are a talkative bunch, but so far, they are eager to learn and very willing to answer questions. I'm looking forward to a great year with them!

SEVENTH GRADE

Math: Today, the class wrote down the rules for adding integers. The assignment is another full page of integer addition with a few integer word problems on the back. The key to understanding integers is to just practice, practice, practice! Here are the rules:

ADDING INTEGERS

When I say, "adding integers" I mean that there is a + sign in between the numbers. You may not actually add the two numbers together:

When the signs are the SAME, add the numbers and KEEP the same sign.

(+3) + (+5) = (+8)      AND   (-2) + ( -9) = (-11)

When the signs are DIFFERENT, subtract the numbers and use the sign of the bigger number. (Remember, by "bigger" we are looking for the number that is bigger without it's sign...or you can think about which number is further away from zero on the number line.)

(+5) + (-9) = (-4) -----------signs are different, so subtract. 9-5=4. And since -9 is further away from zero than +5, you will use -9's sign to make the answer -4.

(-3) + (+10) = (+7) --------signs are different, so subtract 10-3=7. And since +10 is further away from zero than -3, you will use +10's sign to make the answer +7.

Geography: We began painting the continents on our globes today! Some continents are a bit misshapen, but the students are really trying and our goal is to get a good idea of just how big they are and where they are on the globe in relation to the other continents. We will be finishing up by Wednesday.

EIGHTH GRADE

Pre-Algebra: More scientific notation. Remember, you are changing each number into scientific notation. If you start with a really BIG number, the exponent will be positive. If you start with a really small number, the exponent will be negative! Here's the video from Friday. It will help you on today's assignment as well:

Algebra I: Multiplying and Dividing rational numbers. Remember the rule for signed numbers. If the signs are the same, it's positive. If the signs are different, it's negative! It doesn't matter if they are fractions or decimals. You still follow the same rules. Remember, when multiplying fractions, you first look to see if you  need to change any mixed numbers into improper fractions. If so, do the u-turn and then cross cancel. For dividing fractions, remember to change the division to a multiplication and flip the second fraction. Then cross cancel! Send me an email if you get stuck anywhere else. I'm here to help.

Your assignment is #8-94 (or 96?) EVENS only!

See you tomorrow,
