Mardi Gras!

Reminder to all 6th - 8th grade students: Tomorrow is our first house meeting! Don't forget your t-shirts, be in your house mentor's classroom by 8:00, and have your agendas filled out! See you in the morning! (Go Cabrini House!)

Sixth Grade

Investigation 2. Remember, you are just doing the first two drawings. (A & B) Do NOT do C - unless you just want to do one on your own. Also, to plot each point, remember that the first number tells you whether to go left or right, the second tells you whether to go up or down. So if you were supposed to plot (-2, 4), you would go left 2 (negative means left) and up 4, THEN put a dot. Each parenthesis is ONE dot. Connect all the points until you get to a LIFT PENCIL. Then, plot your next dot, but don't connect it to the last dot. When you plot the next dot, begin connecting again.

Seventh Grade

Grammar - pp. 42-43 Exercises A & B. Remember, DO NOT use the arrows! Make three columns: Noun, Linking Verb, Word linked - and write the appropriate words in each column. Do this for both exercises!

Literature - Worksheets over "A Dying Detective". Due tomorrow!

Spelling - Unit 24. First two pages. This is a unit review so make sure you are studying the words I told you would be on the test!

Math - Lesson 6-3. Proportions. Remember, a proportion is just two ratios that are equal. Two equivalent fractions ALWAYS form a proportion. All three of the following are proportions.
In the first one, if you multiply 3 x 2, you get 6 and if you multiply 5 x 2, you get 10. In the second one, if you multiply 4 x 3, you get 12 and if you multiply 7 x 3, you get 21. In the third one, you could tell that it is a proportion by simplifying each ratio first. 0.2 divided by 0.4 = 1/2 and if you divide 1.5 by 3, you also get 1/2. So these are all proportions. To simplify the ratios, just divide the TOP BY THE BOTTOM.

To find out if two ratios are equal, such as the following problems, use equivalent fractions OR cross products.


In the first example, you can see that 8 x 3 = 24, so to find x, just multiply 5 x 3. So x = 15. (That was easy!)

In the second example, use cross products. That means multiply the 4.2 x 0.9 to get 3.78 and the 1.5 x b. You would get the equation:

3.78 = 1.5b

Now, solve for b by dividing both sides by 1.5.

3.78 divided by 1.5 = 2.52

So, b = 2.52

That's it! You are doing #2-17 ALL.

Eighth Grade

Due to the Mardi Gras parade and party, we did not have class. I'll see you tomorrow!
