USING INTEGER CHIPS TO REPRESENT INTEGERS

Integer Chips are coloured disks. ______disks represent +1. ______disks represent -1.

USING INTEGER CHIPS to REPRESENT INTEGER DIVISION

Divide the following. Use a model (integer chips) to help you complete each statement.

Note: The first number represents how many chips you have.
The second number represents how many chips should be in each group.

Example 1: / Example 2:

Now, use the information from above and use it to help you complete the following table.

Example 3: Complete the table.
/ Example 4: Complete the table.

Use the results from the above to complete each statement.

When DIVIDING two integers with the SAME sign, the answer is ______.

When DIVIDING two integers with DIFFERENT signs, the answer is ______.

This is often called the SIGN RULE for DIVISION.

Example 5: Calculate the following. You can use the sign rule to help you out!

a) / b) / c) / d)
e) / f) / g) / h)

Example 6: Mr. Lee paid $60 to get into a 3-D movie theatre to watch Avatar with his wife and another couple. What was the cost of admission per person?

Example 7: Without calculating the answers, identify the quotient with the LEAST value and explain your thinking.

Example 8: Calculate these longer division questions.

a)  / b) 
c)  / d)
