Money
media type="custom" key="766935" Step 1: Find the Common Denominator. In this case it would be 100 since we are using money.

Step 2: Whatever you do to the top you must do to the bottom. media type="custom" key="766949" Step 3: Add the numerators. But the denominators stay the same. media type="custom" key="766951" Step 4: Simplify media type="custom" key="766963"

Clocks
I'll use the same question to show you that you get the same answer. media type="custom" key="766977"media type="custom" key="766985" Step 1: find the common denominator. In this case it would be 60 becuause we are using clocks.

Step 2: Whatever you do to the bottom you must do to the top. media type="custom" key="766993"media type="custom" key="766995" Step 3: Add the numerator's but the denominator's stay the same. media type="custom" key="766999" Step 4: Simplify media type="custom" key="767005"

Double Number Line
I'm going to use the same question again just to show that you can get the same answer. media type="custom" key="767007" Step 1: First think of a number that the number line is going to be out of. it's the common denominator. Since the denominator's are both 4 we will make the number line out of 4. media type="custom" key="767013" Step 2: Find where everything goes on the number line.Then add. media type="custom" key="767023" Step 4: (if you want) You may simplify To 1/2. (2/4 = 1/2)

Standard Algorithm
will use the same question to show you that all these ways above work.

media type="custom" key="767027" Step 1: find the common denominator. (It is already there. 4.)

Step 2: Whatever you do to the bottom you must do to the top. (you don't have to here because we the denominator's are the same)

Step 3: Add the Numerator's But the Denominator;s stay the same. 1/4 + 1/4 = 2/4

Step 4: Simplify media type="custom" key="767037"

Money
media type="custom" key="767261" Step 1: Find the common denominator. Since we are using money the common denominator is 100.

Step 2: Whatever you do to the top you must do to the bottom. media type="custom" key="767273" Step 3: Now subtract the numerator's but the denominator stay the same.

media type="custom" key="767285" Step 4: Simplify! media type="custom" key="767301" media type="custom" key="767309"

Clocks
I will use the same question to show that you get the same answer. media type="custom" key="767311" Step 1: Find a common denominator. Since we are using clocks the common denominator is 60.

Step 2: Whatever you do to the bottom you must do to the top. media type="custom" key="767331"media type="custom" key="767335"

Step 3: Now subtract the numerator's but the denominator's stay the same media type="custom" key="767339"media type="custom" key="767343"

Step 4: Simplify media type="custom" key="767349"

Double Number Line
I will use the same question to show that you get the same answer even with a different stragedy. media type="custom" key="767517" Step 1: First you want to find what your number line will be out of. This is like finding the common denominator. media type="custom" key="767535"media type="custom" key="767543" media type="custom" key="767549" Step 2: Find out where you things are going to be placed on the number line. Step 3: subtracting TIME :3 media type="custom" key="767561" Step 4: If you can Simplify!

Array Model
media type="custom" key="767629" Step 1: Use the denominator's to show the Width and the length of the array model. media type="custom" key="767649" Step 2: Use the numerator's to show how much you color in media type="custom" key="767655" Step 3: The color ones are now the numerator and the all the boxes are the denominator. media type="custom" key="767779"

Mixed Fractions
media type="custom" key="767797" Step 1: Make the mixed fraction into improper. media type="custom" key="767801"media type="custom" key="767805"media type="custom" key="767815" media type="custom" key="767817" Step 2: Multiply the numerators media type="custom" key="767823" Step 3: Multiply the Denominator's media type="custom" key="767827" Step 4: Change Improper Fraction to Mixed Fraction media type="custom" key="767833"media type="custom" key="767843" Step 5: Simplify media type="custom" key="767851"media type="custom" key="767853"
