1. CONVERTING UNITS: LENGTH CONVERSION

2. For Your Notes: Units of Length  1km = 1000m  1m = 100cm  1m = 1000mm  1cm = 10mm

3. The process of converting units of length  To convert length from a larger unit (km to cm) into a smaller unit, multiply by the relevant power of 10.power  To convert length from a smaller unit (mm to m) into a larger unit, divide by the relevant power of 10.  1)Click on the following link and scroll down to the “Converting Metric Units” section.  http://www.mathsteacher.com.au/year8/ch11_peri meter/01_units/length.htm http://www.mathsteacher.com.au/year8/ch11_peri meter/01_units/length.htm

4. Yet Another Way…  The process of converting units can be quite simple if you use the following method  http://alliance.la.asu.edu/geomath/sampler/Zoom WorksheetKeyH.pdf http://alliance.la.asu.edu/geomath/sampler/Zoom WorksheetKeyH.pdf

5. Group Work  In groups work on the converting lengths word document I have provided.  Be prepared to explain how you arrived at your solutions!

6. So Basically…in summary  Check out a math dictionary for kids “chart section” (http://www.amathsdictionaryforkids.com/mathscha rtsIntro.html), after entering the site click on measurementhttp://www.amathsdictionaryforkids.com/mathscha rtsIntro.html  Under “Length” click Metric Units, and review equivalent units at the bottom of the page.  Also under “Length” click Metric Conversions, and review the examples below blue the ovals

7. One More Thing…  1km = 1000m  1m = 100cm  1m = 1000mm  1cm = 10mm  How would the above chart change if we were dealing with unit’s squared?

8. PRACTICE  In our next class we’ll play a game. The theme is who wants to be a millionaire!  *The power point was created by an individual in England so you will be playing for pounds instead of dollars*

9. For Homework  Complete questions 27-32 on page 121 and question 2 on page 55 of Ontario Math workbook 6
