Standard Decimal Notation & Scientific Notation
T.i.P.S.
Students should use their prior knowledge about the relationship between place value system and the powers of 10. Students should understand that for a number used in scientific notation, it must be a number between one and ten multiplied by a power of 10. Students should understand that a negative power of 10 does not imply a negative number but a number less than one, since a negative exponent means division by a power of 10. Students will need to use this knowledge to convert numbers that are written in scientific notation to decimal notation and to convert numbers that are written in decimal notation to scientific notation.
Example
Write the following numbers using scientific notation. 0.000925 3,450,000 Write the following numbers in standard decimal form. 9.25 x 10-4 3.45 x 106
