My friend Randy offered me 2⁄3 of his candy bar. My other friend, Sandy, offered me 2⁄5 of her candy bar. Which of my friends is offering more candy bar?
It’s nice when my friends offer to share.
I love chocolate! I just don’t know which of my friends is offering me more of their delicious candy bar. If you learn about fractions with unlike denominators, then you can help me figure out which friend is offering me more candy bar.
Write the following on a piece of paper:
Circle the name of the friend you think is offering me more candy. Now you can figure out if you are correct.
Make sure you understand the words we use in math to learn this information. Write the vocabulary words "fraction," "numerator," "and denominator," and their definitions, on your piece of paper.
You can find definitions for the vocabulary words at merriam-webster.com and dictionary.com.
One tool that helps you understand fractions with unlike denominators is a fraction bar. A fraction bar is a visual tool that helps you compare fractions. Download the Fraction Bar Visual Aid from Downloadable Resources in the right-hand sidebar.
Color them in, then cut them out, cutting each fraction bar on the dividing lines. Make sure each fraction bar is a different color.
Once you have completed coloring in your fraction bars and cutting them out, use them to figure out the answer to my candy bar problem. Place two of the 1⁄3 fraction bars down on the table. Then put two of the 1⁄5 fraction bars underneath them.
- Which fraction is bigger?
- Did you circle the correct friend?
