Grade 6: Building bigger numbers

Last week, sixth graders explored the Egyptian number system to help them understand how the Hindu-Arabic system (our system) is organized.  Key elements are a base-ten system that uses zero and defined place values.  With this understanding, they have been reviewing naming of large numbers this week.  A quiz on Friday will test their understanding of naming.  Students will need to be able to write numbers through the millions in both words and symbols.








Grade 7: Study Guide: Percentages in action test



PERCENTAGES
A Study Guide

How do you prepare?
·         Don’t try doing it all the night before.  Review a little bit every night. 
·         Figure out what helps you best: 
·         Reading about the ideas
·         Doing problems from the book
·         Explaining to a parent or (smart) older brother or sister what you know
·         Practicing with a friend
·         Checking with Mr. Hughes about ideas you are not clear on (but not five minutes before the assessment)
·         Review the activities that we have done.
·         Review the notes you have written in your notebook.
·         Look at the pages in your textbook.

What should you know?
Equivalents of percentages
·         Know Mr. Hughes’ Famous Fractions and their decimal and percentage equivalents.
·         Be able to find other equivalents
·         Text: pp. 136-140
·         Look at the blog for December 9, 2016 for links to videos and suggestions for IXL lessons.

Percentage of a group
·         If you know the part of a group, what is the percentage?
·         Text: pp. 141-142

Percentage of change
·         If you are given a set of data, can you figure out the percentage increase or decrease?
·         Text: pp.  147-148
·         Here's a video that reviews an increase.  The same will be done with a decrease except that you will get a negative number for your change.  https://www.youtube.com/watch?v=YWOeN7hDD3E
·         IXL: L9, 10

Discounts, taxes, tips, etc.
·         Looking at changing prices either up or down.  How much will you save?  How much more will you need to add for tips or taxes?  How much will the new cost be?
·         Text:  pp. 147-148, 151-152
·         This video reviews the two-step method.  It is OK.  He uses fractions for the first two examples and decimal numbers for the second two.  https://www.youtube.com/watch?v=fZkF2f2nl70
·         This video uses the one-step method.  https://www.youtube.com/watch?v=iJq-zF2tpOE  
·         IXL: Grade 7: M6, 7, 9, 10; Grade 6: V7

Interest
·         How much will you earn over several years if you know what the percentage is?
·         Text: pp. 152-154
·         A basic video.  The quality is not great but he explains it clearly. https://www.youtube.com/watch?v=SD7bQWnUMQU
·         Here’s another one.  It is by an Australian teacher.  https://www.youtube.com/watch?v=WSezCCKYdXQ
·         IXL: Grade 7: M11; Grade 6: V8

What else should you remember?
·         Can you tell if an answer make sense?  Can you use benchmarks to help you?

·         Remember when working with money, that you have to use the symbol or unit and go to two decimal places if needed.

Conferences



Dear Parents,

I am glad that I was able to meet with so many of you and your middle schoolers.  If you were not able to talk with me and would still like to, please send an e-mail message and we can set up a time.

If any of you still have questions related to how the MYP’s grading system works, please take a look at the explanation I posted last week.

Finally, I am going to make a non-math announcement.  TIS’ Project 3580 chapter will be putting on its annual fundraising show on Friday.  Tickets for the show are still available in the Office.  Come and enjoy the performances by students and teachers while assisting a community in Sierra Leone.

I hope you had a good (snowy) weekend!

Sincerely,

Mr. Hughes

Grade 6: Number systems



The sixth grade has started its new unit on Number Systems.  It will be a look at the roles of numbers and the relationships between them.  Students will break numbers down by using prime numbers and factors, as well as creating larger related numbers with multiples and exponential notation.  We will spend some time looking at other systems in order to better understand how ours works.

Having a strong grasp of the basic multiplication facts will be very important in this unit.  If any sixth graders are a little rusty, then some review is a must.  Look at the blog entry for November 15 to see some links and ideas for reviewing.

Below are some photos of sixth graders thinking about where they have seen numbers used and how they were being used (they eventually understood that numbers can be used to measure, count, label or name and to indicate order).

Grade 7: Infographics



The follow-up to watching the “If the World Were 100 People” video was to see how many people those percentages really represented.  Seventh graders looked at a world population of 7.4 billion people and went from there.  They took the statistics and shared them through infographics, a visual way to show different information on a related topic.  Here is a shot of the infographics done by most of the seventh graders (we’re still waiting on a few).
