HMWK: Finish conversion WS from yesterday (see yesterday's post for a link)

PLEASE try the online version of the textbook: www.glencoe.com/ose and access code: (See Mr. F - had to take online code down after getting lots of unrelated traffic)

Today in class:

Discussed that SI and metric are the same, as opposed to our US standard(actually English) system from British Imperial rule. Some very creative arguments for different uses of units; we will put some of these units "on trial" on Monday for some fun argument.

Notes: Conversions - How to use KHDUdcm to move decimals from one unit to another. We applied 2 rules: 1. Find how many steps to move L or R based on the prefixes in KHDUdcm, then 2. move the decimal the same way.

We used many examples and I reminded everyone not to confuse m (for meter) with m_ (with another letter) as the symbol for the mili-prefix.

Most classes got their measurement lab well underway; (4th and 3rd? ) periods didn't get to start. We'll finish the measurement lab on Monday.
