Chapter 1
Fraction Models and Unit Fractions
Equal Parts Make Fair Fractions
A fraction shows equal-sized parts of one whole. If a sandwich is cut into 4 equal pieces and you eat 1 piece, you ate 1/4 of the sandwich. The pieces must be equal, or the fraction would not be fair.
We will use pictures and number lines to see fractions clearly. You will discover that a fraction has a special part called a unit fraction. This helps us understand and compare fractions.
Seeing Unit Fractions
A unit fraction is a fraction with 1 as the top number. It names one equal part, such as 1/2, 1/3, or 1/8.
The bottom number tells how many equal parts are in the whole. It is called the denominator. The top number tells how many parts we have. It is called the numerator.
For example, 3/5 means 3 parts out of 5 equal parts. Its unit fraction is 1/5.
We can use an area model, which is a picture of a shape split into equal parts. A rectangle split into 6 equal boxes shows sixths. One colored box is 1/6. Four colored boxes are 4/6.
A number line also shows fractions. The space from 0 to 1 is the whole. Split it into equal spaces. If you split it into 4 spaces, each jump is 1/4.
One Example with Apple Slices
Look at an apple cut into 4 equal slices.
1. Count the equal slices: there are 4. 2. The denominator is 4, so each slice is 1/4. 3. Color 3 slices to show how many slices are chosen. 4. Write the fraction: 3/4. 5. On a number line from 0 to 1, make 4 equal jumps and stop at the third jump.
The unit fraction is 1/4, and the amount chosen is 3/4.
Draw, Match, and Find
Draw a rectangle and split it into 3 equal parts. Color 1 part. Write its unit fraction.
Draw a number line from 0 to 1. Split it into 5 equal spaces. Circle the point at 2/5.
Match each fraction to its unit fraction: 2/6 with 1/6, 4/8 with 1/8, and 3/3 with 1/3.
Color 2/4 of a row of 4 toy blocks. Then draw a number line showing 2/4.
Can you find a food at home that can be split into equal parts, and draw its unit fraction?
