Comparing Fractions and Decimals

- NS 1.1 Compare and order positive and negative fractions, decimals, and mixed numbers and place them on a number line

- Convert them into equivalent fractions that have a common denominator, then compare the numerators.

- How do we compare fractions?

- >, <, or =

- Order from least to greatest:

- Line up the decimal points vertically and compare from left to right.

- How do we compare decimals?

- 1.992.032.42.00
- 2.4, 2.03, 2, 1.99

- Order from greatest to least: 1.99, 2.03, 2.4, 2

- Convert the fractions into decimal form by doing long division.

- How do we compare fractions and decimals?

- >, <, or =

- We will work together on comparing decimal and fraction problems

- To connect two dominoes, the sides that touch must have the same value.
- One side will be a fractionand the other side willbe a decimal. You andyour partner must calculatewhich dominoes may be placednext to each other.
- Example: ½ = 0.5 so if one domino has ½ and other domino has 0.5, you may place the dominoes together as long as the ½ and 0.5 ends are touching.

- We are continuing ST Math’s unit on equations
