Suprising Number Patterns III

Here are some more charmers of mathematics that depend on the surprising nature of its number system. Again, not many words are needed to demonstrate the charm, for it is obvious at first sight. Just look, enjoy, and spread these amazing properties to your students. Let them appreciate the patterns and, if possible, try to look for an "explanation" for this. You might ask them why multiplying by 9 might give such unusual results. Once they see that 9 is one less than the base 10, they might get other ideas to develop multiplication patterns. A clue might be to have them consider multiplying by 11 (one greater than the base) to search for a pattern.

A similar process yields another interesting pattern. Might this give your students more impetus to search further?

suprising number pattern 9

Now the logical thing to inspect would be the pattern of these strange products.

suprising number pattern 10

How might you describe this pattern? Let students describe it in their own terms.
