How do you round decimals?

• Draw 2 number lines the same length. On each number line, divide the whole distance between 0 and 1 into the number of equal-sized parts shown by the denominator.

The top number line has 5 equal-sized parts. Each part is . The bottom number line has 6 equal-sized parts. Each part is .

• On the top number line, begin at 0 and count forward 3 of the 5 equal-sized spaces. This is of the distance between 0 and 1.

  

• On the bottom number line, begin at 0 and count forward 5 of the 6 total spaces. This is of the distance between 0 and 1.



• Remember, as you move from left to right on a number line, the numbers get larger.

The fraction is greater than because it is farther to the right on a number line.
