6. Division Models Essential Understanding:
Double bar graphs/ fraction strips are an easy way to illustrate fraction equations involving division.
To do this:
Begin by drawing two bars of equal length, one above the other.
The top bar will represent the dividend and the bottom bar will represent the divisor.
Remember to draw the missing portions of wholes, if the dividend is a proper fraction.
Example:
Now, divide both bars into equal sized parts to represent any wholes in your dividend. If you dividend is a fraction the entire bar will represent 1 whole.
Next, Divide the wholes in the top bar, to represent the denominator of the dividend.
Then, shade the specified fraction.
Now, divide the wholes of the bottom bar to represent the denominator of the divisor.
Finally, use the numerator of the divisor to determine how many parts per group need to be circled.
The number of groups you can create is the answer to the equations.
Don’t forget to account for any unfinished groups.
