What’s Goin’ On In Room 133

OK, Colleagues – for those of you who could have found better success on that last test (in other words, if you scored less than 70%) , this is your opportunity to get a passing grade in the books for this lesson.   And for those of you who wanted a better score than you got, this is your opportunity to raise it to the next letter grade.  (It’ll look real good on that report card!)

Print out the following worksheets.   There are some fill-in the blank notes (use your text, interactive notes and the old noodle!).  There are a few questions to do on the worksheet themselves.  And, on the second page of each sheet, I have a list of questions from your textbook* that you have to tackle.   Complete everything and bring it in for credit – or extra credit, if you’re into that sort of thing ! 

7.1 Test Make-up Fractions Percents

7.1 Test Make-up Scientific Notation

Git ‘er dun – and git yer grade right!  

(*Enriched Math: these questions are in the blue textbook, so see me if you want in on this!)

You have your sheet of fractions, Colleagues.  You need to annotate the decimal equivalent in the upper left corner and the percentage equivalent in the lower right corner of each fraction’s square.  (Sure hope you brought it home!  :0  If I find an e-version of the handout, I’ll post it here later this evening.)

Enriched Math Folks and anyone else up to the challenge:  We got to Scientific Notation and talked about using it for big numbers 93,000,000 miles between the earth and the sun.  And you also know that it can be used for small numbers too.  Can you figure out what the scientific notation is for any of the fractions on that sheet?  Hmmmm…

Rock on, Colleagues!    (Quiz tomorrow!)

The Decimal Point, that is?  We have looked at fractions and ratios and we now turn our attention to another fashionable form of a fraction, the dashing, the debonaire – the Decimal.  Yes, nation, even though this formidable fraction has been stripped of its elegant fraction bar, it is still considered a fraction, one that has gone through a unique transformation.  Yes, it has distinguished itself by actually dividing the numerator by the denominator – using long division, no less! – and for that we award it the noble Decimal Point.  The number that results from our division takes its place (or places) in our mathematical pantheon of heroes otherwise known as our base-10 system.  And the places that it holds are the tenths (1/10ths), the hundredths (1/100ths), the thousandths (1/1,000ths) and so on.

Wow, what would we ever do without it?  So take a look at page 556 in the text and run through questions 1- 28.  We’ll also have a few worksheets to keep ourselves in shape as we prepare to do the heavy lifting to come!
