So we ended up with some form of these 3 equations in both classes today…

I got tired of writing step # and total blocks so I asked if we could shorten it a bit…so we defined n and x as those quantities!

And majority of students raised their hand saying those equations looked hard or confusing…

Until…we picked a step number.  Woe.  That’s doable.  We substituted 4 as our step # and all they saw was addition, subtraction, multiplication, parenthesis…  we just went from this complicated thing to something I even do without a calculator!

And the arithmetic showed each equation actually resulted in the same values.
