Decimal Models Tenth Hundredth
Equivalent Decimals Decimals that represent the same value Example:0.6 is equivalent to 0.60 0.6 = 0.60
Terminal Zeroes Zeroes as last digit(s) of a number can be removed0.6 = 0.60
Equivalent Decimals 0.6 0.60
Comparing Decimals Step 1:Underline the first number that is different in the numbers being compared
Add terminal zeros so there are the same number of decimal placesComparing Decimals Step 2: Add terminal zeros so there are the same number of decimal places
Comparing Decimals Step 3: Remove the decimal point
Order numbers depending on the directions givenComparing Decimals Step 4: Order numbers depending on the directions given
Replace decimal point and remove terminal zeroesComparing Decimals Step 5: Replace decimal point and remove terminal zeroes
Which is greater: 0.6 or 0.58 ?
0.60 0.58 0.6 > 0.58
Which is greater: 0.6 or 0.58 0.6 0.58
Underline decimal place we are roundingRounding Decimals Step 1: Underline decimal place we are rounding
Circle the number to the right of the underlined decimal placeRounding Decimals Step 2: Circle the number to the right of the underlined decimal place
Rounding Decimals Step 3:If circled digit is greater than or equal to 5, then round the underlined number up (add one)
Rounding Decimals Step 4:If circled digit is less than or equal to 4, leave the underlined number the same
