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.
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)
