I can compare and order rational numbers

Compare and Order Rational Numbers

Essential Understanding: It is easy to compare and order rational numbers

(i.e. fractions, decimals, and percent).

• Begin by expressing all the given numbers in the same form. Decimal form is the quickest, but you can use fraction or percent, as well.

Example:

• Next, use your knowledge of place value or common denominators to compare or list the numbers in the order they are asked (typically from least to greatest).

Create and identify intervals on a number

line.

Number LinesEssential Understanding: • Number lines can be drawn horizontally to display numbers in order from

least to greatest (left to right). Ex.• Number lines can also be drawn vertically to display numbers from greatest

to least (top to bottom).Ex.• Number lines can be drawn to represent any number set (beginning and

ending with any number).Ex.• Number lines drawn to illustrate both positive and negative numbers, are

created by placing a zero in the middle and continuing to number in each direction from there.

Ex.• Each tick mark represents a fraction of the number line. You can count these

marks to determine the interval. Ex.

I Can….

Locate and place positive rational

numbers on a number line.

Rational Numbers on a Number LineEssential Understanding:

• To determine the value of a plotted point, you first identify the value of each tick mark. This is done by counting the tick marks between two whole numbers. Begin counting with the first tick mark after a whole number and continue counting until you reach the next whole number (include the second whole number in your counting).

• Example

• The number of tick marks counted represent the fraction the number line has been divided into.

Example:

• You can use this knowledge to label each tick mark as a fraction, decimal, or percent and locate or identify given points.

Example:

Bell Work1. Convert each number to all 3 forms (fractions, decimals,

and percent).

2. Then, create a number line to illustrate their positions and

relationships to one another.

3. Create 2 inequalities using the number line you have

created.

Numbers: 25%, 0.6, 98%, 0.5,

Finding the whole given the part and percent.

Essential Understanding:To find the whole, when given the part and percent, you simply change the percent to a decimal and divide the "part" by the percent.
