Show Me With The Money Presented by A. Dávila, Ed.D. Scientific Notation and Standard Form Created by Dr. A. Dávila Scientific Notation: a way of writing a number as a product of two factors x Scientific Notation: a way of writing a number as a product of two factors The first factor has exactly one nonzero digit to the left of the decimal point x Scientific Notation: a way of writing a number as a product of two factors The first factor has exactly one nonzero digit to the left of the decimal point (less then 10 but greater than 1) The second factor is a power of ten x 10 Place Value Review The value increases 10 times more than the previous value. The ones is the starting point (no powers of ten) Ones 1 0 10 multiply by 10 The value increases 10 times more than the previous value. Tens 10 from the ones place to the tens place (10 times more) Tens 10 1 x 10 Tens 10 1 x 10 1 10 One power of ten Various methods of representing the Tens Place Tens 10 1 10 multiply by 10 The value increases 10 times more than the previous value. Hundreds 100 Hundreds from the tens to the hundreds 100 place (10 times more) 10 x 10 Hundreds 100 10 x 10 10 2 two powers of ten Various methods of representing the Hundreds Place Hundreds 100 2 10 multiply by 10 As you continue to the left (higher value sections) in the place value chart, the value increases 10 times more than the previous value. Thousands 1,000 Thousands 1,000 from the hundreds 10 0 x 10 to the thousands place (10 times more) Thousands 1,000 10 0 x 10 10 x 10 x 10 Thousands 1,000 10 0 x 10 10 x 10 x 10 10 3 three powers of ten Various methods of representing the Thousands Place Thousands 1,000 3 10 multiply by 10 As you continue to the left (higher value sections) in the place value chart, the value increases 10 times more than the previous value.
