What is four times three? 12 you might say, but no longer! In a new type of math— intersection math—
we will see that four times three is 18, two times two is 1, and that two times five is 10 (Hang on! That’s
not new!) Let’s spend some time together exploring this new math and answering the question: What is
1001 times 492?

To fill in each box, add the numbers in the two boxes above it. For example, the box in the middle of the third
row should have a 2.
When you are finished, turn the paper over and color the odd numbers in the triangle to discover a neat pattern.
Why do you think this pattern occurs? (Hint: What happens if you add two even numbers? Two odd numbers?
An even number and an odd number?)
