9/14 – Thursday “A” Day – 

 
Main focus:   
 
1. To Round calculates values either by the Accuracy Rule or the Precision Rule.
2. To Round a conversion correctly.
3. To Identify constants as numbers that are not considered for rounding.
 
Period  6:
 
1.  We will review the homework form based on the following worksheet.  
 
Measurement and Sig Figs – RAT 4 – 22-23.pdf
 
2. Quick review of significant figures and their origin (measurements!!)
 

3.  We will spend more time reviewing and understanding how and why we round using significant figures (Accuracy Rule) and decimal places (Precision Rule) using the worksheet handed out last Thursday and our class notes.

We will also complete the bottom questions of the sig fig ditto.pdf – Specifically we will use scientific notation to help round number that would normally be impossible.
 

 
       a) We will also revisit the metric conversion worksheet 2 – AND NOW round correctly!!!!
          Remember that we only compare sig figs with measured value. Constants like 3.14 are not used to                                    determine  the rounding.
