We've started a new chapter in my Algebra 2 courses, this one on statistics. Today we learned how to calculate a standard deviation, which involves, among other calculations, determining how far from the mean each data point is--that's right, simple subtraction.
Now I'm no Luddite, I allow students to use calculators for this exercise. I did, however, want them to actually use the formula to calculate the standard deviation, not just input the data into the calculator and use its internal programming of statistics functions to come up with the "standard deve"--at least for this introductory exercise. I want the students to get an idea of where the standard deve comes from, and not be just "some number the calculator gives me".
One student asked me today if he could round off his average, presumably to a whole number, instead of entering it to however many decimal places each time--because typing all those numbers is just too strenuous.
I replied in a manner similar to this: "Let me get this straight. The calculator is doing all the calculations for you, and you don't even want to type the numbers into it?"
Perhaps I was wrong in this post, perhaps punching buttons on a calculator does qualify as a kinesthetic activity.
