OBECTIVES:  After today's lesson students should be able to...

• solve problems using dimensional analysis (DA)
• interconvert metric units using DA or "sliding the decimal
• commit metric prefixes to memory as listed on today's handout: nano (n-) - Giga (G-)

CLASS LESSON

1. Students should take out assignment from last day.  Lead students to make a "mind map" of the units for the Prima Numero worksheet.  Use this (and point to it frequently) while students solve problems on the board [see below]
2. Grade "The Digitatsu of Prima Numero" ... the invented units - in class.  Have students solve problems on the board.  Write only equivalent expressions ... no need to actually produce the final answer as a single number.
3. Demonstrate Metric Units and their conversions and equivalency's on the board.
4. Identify pre-fixes that students should memorize and know:  Giga-Mega-kilo-[standards:  s, m, g, L]-deci-centi-milli-micro-nano
5. Assign Dimensional Analysis of Metric Units worksheet.
6. Students work on assigned work in class.
7. Remind students:
   1. Review is next period in class (Wednesday).
   2. Summative paper test on last class this week (Thursday). 
   3. Reflection will be due next Monday.  Reflection is podcast this time; we will go over that on Wednesday or Thursday this week.
