Read this number:
17. 008
17 and 8 thousandths
List the place value of the first three digits after a decimal point.
tenths, hundredths, thousandths
How many decimal places do you need to have a number in the tenths?
1
How many decimal places do you need to have a number in the thousandths?
3
How many decimal places do you need to have a number in the hundredths?
2
Steps to rounding?
1. Circle the digit in the place you are rounding to
2. Underline the digit to the right.
3. Ask yourself if the underlined digit is 5 or greater
4. If it's 5 or greater, round the circled digit up. If it's less than 5 the circled digit stays the same

Answer to a multiplication problem
What is a factor?
The numbers you multiply together to get a product
What do you do with the decimals in an addition or subtraction problem?
Line them up!
Do you line up decimals in a multiplication problem?
No, but if they happen to line up it's OK.
Where do you put the decimal in the answer to a multiplication problem?
Count the number of decimal places in the problem, then move from right to left that many number of spaces in the answer.
Quotient
Answer to a division problem
Divisor
Number on the outside of the division sign. The number being "divided into" another number
Dividend
Number on the inside of the division sign. The number being divided.

Move the decimal straight up to the quotient. Divide the numbers ignoring the decimal.
Steps to division
Divide, Multiply, Subtract, Compare, Bring Down
What does the line in a fraction mean?
Divide
How do you divide a larger number into a smaller one?
ex: 4/5
Add a decimal and zeroes after the four. Bring the decimal straight up to the quotient and divide.
How do you simplify a fraction?
Divide the numerator and denominator by the same number until you cannot divide any more.
Numerator
Top number in a fraction
Denominator
Bottom number in a fraction
How do you change an improper fraction into a mixed number? ex: 13/5
Divide. 13 divided by 5 = 2, there is a remainder of 3. The 2 is the whole number, 3 is the numerator, and the denominator stays the same. 2 3/5
Mixed number or Mixed numeral
A whole number and a fraction
Improper fraction
The numerator is larger than the denominator
How do you change a mixed number to an improper fraction? ex: 2 6/7
Muliply the denominator and the whole number then add the numerator. Denominator stays the same. 2 6/7 = 7x2+6 over 7
How do you add or subtract fractions with unlike denominators?
Find the lowest common denominator, then make equivalent fractions
