READ the LO, What vocabulary do you need to know?

Sometimes it is not convenient to write a number in standard notation (the notation used to write numbers, Ex. 1,520,000; 0.00052 etc.)  especially when the numbers are very large or very small numbers with many decimal places or zeros.  You can rewrite a very large and very small number in a more convenient way called scientific notation.

Scientific notation must follow specific rules to be in proper scientific notation.

Scientific notation expresses a number in standard notation as the product  of two factors , where the  1st factor is greater than or equal to 1 and less than 10  and the 2nd factor is always a base of 10  raised to the power of an exponent.

What is scientific Notation?

(Highlight the part of the passage that defines scientific notation)

Sometimes it is not convenient to write a number in standard notation (the notation used to write numbers, Ex. 1,520,000; 0.00052 etc.)  especially when the numbers are very large or very small numbers with many decimal places or zeros.  You can rewrite a very large and very small number in a more convenient way called scientific notation.

Which TWO statements about standard notation is correct?

How is scientific Notation expressed?

CHECK FOR UNDERSTANDING

The 1st factor in scientific notation must be written PROPERLY.

1) ONLY 1 digit before the decimal, which cannot be 0.

2) No Leading 0 or trailing zeros.

3) Single digits numbers do not require a trailing 0. (Example 3)

4) 2nd factor in scientific notation must ALWAYS be a base of 10.

Select ALL the values written in proper scientific notation.

A large number greater than 1 will have a __________ exponent when converted to __________ notation.

A small number less than 1 will have a __________ when converted to __________ notation.

CHECK FOR UNDERSTANDING 2:

1)Evaluate each expression in Scientific Notation and Standard Notation.

2) Determine if the exponent will result in a number greater than 1 or less than 1 when converted into Standard Notation.
