What’s Goin’ On In Room 133

Archive for October, 2009

Alex and 11 friends are celebrating Alex’s birthday.  His mom plans to distribute tokens for purchasing prizes to Alex and his friends.  Each person will receive 8 quarter tokens and 3 dollar tokens. 

Use the distributive property to describe this plan. 

(This is a GOOD one!)

Diane tried to solve the following puzzle: 

( _____   x  ______  )  divided by 2  ( _______ ) = 1. 

 According to the directions, she must fill in the blanks with the numbers 3, 4 or 6, one number in each blank.

Diane found two ways to solve the problem.  Can you find the two solutions?  What property is illustrated?  Explain your answer.

Read page 30 – 31.   Study Examples, Key Concepts and Vocabulary.  Do Questions 1 – 3 on page 32 in your Math Journal.  (DUE ON WED, OCT 28th)

Read your text, pages 23 thru 25.  Study Examples, Key Concepts and Vocabulary.  Do Questions 1 – 3 on page 26 in your Math Journal.

You can handle it, Colleague!  That’s why we have all those review problems on Statistics and Integers.  You don’t have to do them all.  Just concentrate on the ones that are the trickiest for you, and make sure you have those critters figured out. 

And as for the ones that you know cold – just run through one or two (SHOWING ALL YOUR WORK!), you know?  Just to make sure you don’t throw away any easy points !

ADDED NOTE: If I spoke with you today and you need that extra credit to boost those Test scores on Statistics and Integers, you know what you have to do.  The full 9-page Review Packet and the front page of the one with all the Dump Your Brain notes on it, both Examples section and the Mixed SOL Review section.  If you want it to count, bring it in on Monday.  I am looking forward to adjusting those scores ! 

Monday is going to be Great Day, dear colleague!  Rock on!

Take up the challenge to make up your grades, Colleagues! 

Some of you need to make up for the score on your Integers Test.  Some of you need the extra practice.  And some of you need the extra credit! 

The review packet (which most of you will get it on Friday) has a lot of good tips and examples – as well as some great word problems.  (Eleven of them on the 7.5 Integers section, as a matter of fact.) 

Come see me and let’s talk about how many you will need to do to make up your grade!  Essayons!

This problem is one that we talked a little about in all of our classes, but Enriched Math got it for homework.  Seems to me that we really ought to spread the wealth here because this was good practice.  (One of our classes actually got to finish this in class today.  That was good work!)

Rock on, Colleagues!

OK, Colleagues – illustrate these four different math sentences:

8 – 2 = 6

-8 – 2 = – 10

8 – ( – 2 ) = 10

-8 – ( – 2 ) = – 6

Try to show them in different ways, such as using the number line to show movement of operation or relative positions, using positive and negative icons/symbols, or in a way that YOU see is mathematically sound.  Looking forward to viewing your work.  We’ll count these as due on Wednesday the 14th.

Check it out, Colleagues!   Turn your blue Math textbook to page 136, and do the EVEN-numbered questions only from #14 – 26.  And again on page 140, even-numbered only, from #12 – 24.   These are due on Wed Oct 14th.

This link gives you our discussions during the first week of October, 2009.  It covers number sets, and adding & subtracting negative integers.
