Students investigate how the quotients and remainders from integer division relate to the quotients from rational number division in both fraction and decimal form.

Students will explore the following concepts in this activity:

• division
• fractions
• whole numbers
• decimals

Distribute student activity sheet to the class. Pose a simple problem like this one:

If you had 10 cookies to divide evenly among 3 people, how any cookies would each person get? Have students act out the division with counters. (Or, use the cookie pictures provided with activity. )

Ask students: What would you do with the leftover cookie? Discuss the two choices. Leave the cookie alone and let it be left over, or cut it into three equal pieces to give to the three people. Determine the whole number quotient and the whole number remainder.
