Write Them as Fractions

Work with your group to complete the table. In each column, write fractions that are equivalent to the whole number in the top row.

Step 1: Write two fractions that are equivalent to each whole number (six fractions in all). Pass your computer to your right.
Step 2: When you receive your neighbor’s computer, write a new fraction that is equivalent to a whole number.
Repeat Step 2 until the table is complete.
