10. Conversions King Henry Died By Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Problem – Convert 22cm to meters.

11. Conversions King Henry Died By Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Start at CENTI *

12. Conversions King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Move 2 Spaces to the left – to base unit (which in this case is METER) * 2 1

13. Conversions King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit Each move to the left represents a division by 10. DIVIDE 22 by 10 twice (or divide once by 100)……. 22 divided by 100 = 0.22 22cm=0.22m

14. Conversions King Henry Died Monday Drinking Chocolate Milk ============================================= Kilo Hecto Deca Base Deci Centi Milli Unit If the problem requires you to move to the RIGHT then you MULTIPLY by 10 as many times as you moved to the right

15. Make a Chart in Your Notes 5 Columns 7 Rows Make the spaces big enough to write in

16. Insert Headings for the Columns BASE UNITTYPE OF MEASUREMENT FORMULATOOL

17. Insert Row Titles: BASE UNITTYPE OF MEASUREMENT FORMULATOOL LENGTH AREA VOLUME OF A REGULAR SOLID VOLUME OF A FLUID VOLUME OF AN IRREGULAR SOLID MASS

18. What is the base unit used when measuring length?

19. BASE UNITTYPE OF MEASUREMENT FORMULATOOL LENGTH Meter (m) AREA VOLUME OF A REGULAR SOLID VOLUME OF A FLUID VOLUME OF AN IRREGULAR SOLID MASS

20. A DIRECT MESUREMENT is taken when the measurement can be read directly off the tool – no math is required. Is the measurement of length a DIRECT or an Indirect measurement?
