Chp. 3 Assessment

Hey guys. Just wanted to give you a quick rundown of what's going to be on your Chapter 3 Assessment next Tuesday.

We will  be covering sections 1 - 6:

1 - Rounding/estimating (remember place values and how to round decimals)
2 - Estimating products and quotients (round the numbers first; then, solve using your new numbers)
3 - Mean, Median, Mode & Range
4 - Using formulas (plug in what you know; solve for what you don't know)
5 - Solving Equations by adding/subtracting decimals
6 - Solving equations by multiplying or dividing decimals

Please be sure to bring a calculator. Happy studying!
Oh, and just one more thought from Philosoraptor...

Assignment for Thursday, 11/21

Hello my friends. First, let me thank you for your kind words and support today. You all helped me get through the day and I appreciate it. :)

Tonight for HW, we're going to use the honor system. Pleeeeeease don't use a calculator; you will have a drill tomorrow that will require your awesome brains without one. It will not be graded for correctness, but I'd like to see where we all are in terms of decimal skills.

Try the exercises for multiplying and dividing decimals, as we move into the section for solving equations by multiplying and dividing decimals. This should be review for most of you, but if not, no worries - we will take the time to go over it before we move into the section. Once we're all on the same page and can do it by hand, we'll break out the calculators. Here are the links. Complete several of each and see how you. do.

See you tomorrow!

Equations Game

Howdy!

Today you'll be playing some team games to practice what we've learned about solving equations with decimals. Display the One Step Equation game on the Polyvision board (click this link):http://www.math-play.com/One-Step-Equation-Game.html. Select the 1-player game. Be sure to select the "superstar" level option when playing the game. Please designate a classmate to keep score on the chalkboard.

Divide your class into two teams. Boys vs. girls worked well last time if you'd like to do that again. Take turns going up to the board to answer the questions with the eno pen. Remember to take your calculator with you (or a notebook and pencil).

Team 1 will send a player to the board to complete a problem. Correct answers score 1 point. Incorrect answers score no points. After the first player from Team 1 has gone, Team 2 will send a player to complete a problem. Then Team 1 will send another player, and so on, alternating between your two teams. The team with the most points at the end of the game wins. Have fun!

So far in Chapter 3...

I just wanted to take a second and briefly review what we've learned so far in Chapter 3.

1. Rounding & estimating with decimals
    ---Remember your place-values when being asked to round to a specific number.
    ---The rule is "5 and above, give it a shove; 4 and below, let it go."
    ---Remember that, after we round a number, we drop the digits that came after the digit we've rounded

2. Measures of Central Tendency
     ---Mean, Median, Mode, & Range are all ways to measure/describe/analyze a set of data
     ---Mean: Average // Median: Middle # // Mode: # that appears most often // Range: Highest - lowest
     ---***Take a look at the previous post for some creative math notes!

3. Formulas
    ---To solve a formula, simply plug in what you know (the numbers you are given) and solve for what
         you don't know (the unknown variable).
 
3. Solving Equations with Decimals
     ---Solve these the same way we solve equations with whole numbers - perform the inverse operation
          to solve for the variable.
     ---Now that we've practiced adding/subtracting decimals and have demonstrated that we can complete
         these operations without our calculators, we can use our calculators for assignments which require
         adding and subtracting decimals.

Mead, Median, Mode & Range!
