Finding and using a pattern is an important problem-solving skill you will use in algebra. The patterns in Diamond Problems will be used later in the course to solve other types of algebraic problems.
Look for a pattern in the first three diamonds below. For the fourth diamond, explain how you could find the missing numbers (?) if you know the two numbers (#).
Copy the Diamond Problems below onto your paper. Then use the pattern you discovered to complete each one.
What do you do to each of the # numbers to get to the ? numbers?
See the diamonds below.
In the example diamonds, notice how the two side numbers added together equal the bottom number, while those same two numbers multiplied equal the top number.
