The odd numbers are sandwiched between the squares? Take some time to figure out why — even better, find a reason that would work on a nine-year-old.
Exploring Patterns We can explain this pattern in a few ways. Try drawing them with pebbles Notice anything? How do we get from one square number to the next?
Well, we pull out each side right and bottom and fill in the corner: Each time, the change is 2 more than before, since we have another side in each direction right and bottom. Because the change is odd, it means the squares must cycle even, odd, even, odd… And wait!
Funny how much insight is hiding inside a simple pattern. What is this, ancient Greece? No, the modern student might argue this: Indeed, we found the same geometric formula.
But is an algebraic manipulation satisfying? Calculus Madness Calculus students may think: Close, but not quite! Forget about the limits for now — focus on what it means the feeling, the love, the connection! Going from 32 to 42 would mean: The equation worked I was surprised too.
My pedant-o-meter is buzzing, so remember the giant caveat: Calculus is about the micro scale. Lessons Learned Exploring the squares gave me several insights: Seemingly simple patterns 1, 4, 9, 16… can be examined with several tools, to get new insights for each. Analogies work on multiple levels.
Calculus expands this relationship, letting us jump back and forth between the integral and derivative.
