Thursday January 24th - Investigation 3.3

In this next Investigation 3.3 students are comparing and scaling unit rates.
Specifically they were faced with two different cd deals.
The students were tasked with scaling down the deals to a unit rate and then creating an equation out of that unit rate (this is review from Variables and Patterns our first Unit).

Here is a helpful video if you want to watch more on Unit Rates.
Video 1 - Unit Rates
Video 2 - Comparing Unit Rates

Wednesday January 23rd - Investigation 3.2

Investigation 3.2 p. 42

Today we discussed unit rates in terms of time, distance and speed.
Students had to :

• Further develop an understanding of unit trates and how to compute and interpret them.
• Work with the important application of rates to miles/ hour (speed).
• Apply the understanding of average speed or rate of progress.

Thursday/ Friday January10th/ 11th

Investigation 2.1 p. 22-23 in the text.

The mathematical goal for the next two days is for students to become comfortable with writing ratios and related forms of comparisons to solve problems.

The following is the provided note sheet we completed together in class for the investigation.

Students had two days in class and the weekend to complete ACE Problems # 1, 2, 3, and 9, 10, 11, 12, 13.  These will be due Monday along with a binder organization check.

Wednesday January 9th - Check-in Investigation 1

Today students took the Investigation 1 Check-in for Comparing and Scaling.
