Tuesday January 8th

We completed the End of Investigation Reflection on p. 21 in the text giving examples and telling what each of the following comparisons mean:
   - ratio
   - fraction
   - percent
   - difference

The students then started the Additional Practice Sheet for Investigation 1.
Here is the link to the worksheet and the answers.

Friday January 4th - Investigation 1.1

Today we covered investigation 1.1 -  Making Comparison Statements.

We focused on two goals today:
1. Explore strategies to compare information
2. Use the language of ratios

Thursday January 3rd

Today we started Investigation 1.1 in the new Comparing and Scaling Book.
We focused on the ability to make comparisons of quantitative data.
We focused on making comparisons through:
1. ratios
2. differences
3. percents
4. simplified ratios

Here are the notes from today.

Comparing and Scaling the Next Unit

Dear Students and Parents,

The next unit in your child’s mathematics class this year is Comparing and
Scaling: Ratio, Proportion, and Percent. Students look at problems involving
many situations and learn to make comparisons using ratios, fractions, percents,
and rates.

UNIT GOALS

One goal of this unit is to develop students’ abilities to make useful comparisons
of quantitative information using ratios, fractions, decimals, rates, unit rates, and
percents. A second goal is to have students learn to use quantitative comparison
information to make larger or smaller scale models.  Students should also learn different ways to reason in proportional situations and to recognize when such reasoning is appropriate.

Hello everyone and Happy New Year!

I wanted to share some good practice sites for order of operations in case you wanted to practice on your own - we will talk more about these in class, but I have noticed that some of you need a little more work in this area so try some of these:

https://www.khanacademy.org/math/arithmetic/multiplication-division/order_of_operations/v/introduction-to-order-of-operations?topic=order-of-operations

https://www.khanacademy.org/math/arithmetic/multiplication-division/order_of_operations/v/more-complicated-order-of-operations-example?topic=order-of-operations

http://www.basic-mathematics.com/order-of-operations-game.html

and this one - but run it in chrome or safari - http://www.shodor.org/interactivate/activities/OrderOfOperationsFou/

Have fun practicing!

Dec 21st - January 1st 2013

Have a safe and enjoyable set of Holidays!
See you in 2013!
