Today's Goal: Today students will be able to express positive and negative fractions as decimals.
Vocabulary:
Rational Number: Any number that can be written as a fraction.
Terminating Decimal: Changing a fraction into a decimal using division where the division problem comes to a definite end.
Repeating Decimal: changing a fraction into a decimals where the division problem does not end, but rather a number or series of numbers repeats forever.
Bar Notation: Used to indicate the number pattern that repeats indefinitely by placing a bar (line) over the repeating number or numbers.
Terminating Decimals
When changing a fraction into a decimal remember that the line between numerator and denominator means division. The numerator (top number) is the number being divided, the dividend. It goes inside the division problem. The denominator is the divisor so it goes outside the division problem. Then divide normally, annexing zeros if necessary. This is an example of a terminating decimals as it ends and does not go on forever.
