“237,600 miles is the average distance between the earth and the moon, a number which suggests an intriguing inner harmony to our universe, for it is thirty diameters of the earth, sixty radii of the earth or 220 moon radii. The mystical author and numerologist John Michell would reveal these figures with the full force of a revelation during his lectures. A self-declared ‘radical traditionalist,’ Michell campaigned long and hard against the destruction of England’s ancient number systems in favor of the decimal system.”

As a child, I enjoyed math in school and did fairly well at it. I liked the symmetry and order of numbers, and found multiplication a particularly scintillating procedure (and yes, I am serious; I was a weird kid). By the time I crossed the Rubicon from fractions and decimals into algebra, I could already see I was in trouble. For some reason, I could never get right orders of operations and other algebraic procedures. For some reason I felt, and continue to feel, ashamed of this intellectual inadequacy.
Of course, I am tempted to blame my math teachers in middle school, who were indeed dismal; both of my eighth grade math teachers clearly hated kids. Since I was getting more than enough of that sentiment elsewhere in my life at the time, I avoided them. So I suppose I am at fault as well.
Unsurprisingly, I have been and remain a terrible math teacher. I’ve developed some literacy lessons on both math and science, but they are more reading comprehension work than actual cognitive work in the domains themselves. That said, I have become interested (to some extent for obvious personal reasons) in helping struggling students improve their own understanding of the math curriculum they are expected to master. To that end, I’ve proposed to a colleague in the mathematics department at my school that we collaborate on developing some math learning supports for our struggling students.
This morning I wrote this super multiplication table as a start on this endeavor. I know this doesn’t necessarily augur great sophistication in this project; it’s worth considering, however, how many students who struggle with math do so because they never learned their multiplication tables. As with all of the material posted on Mark’s Text Terminal, this is a Microsoft Word document that you can chop and repurpose as many times as your circumstances require. Indeed, you may end up with as many versions of this as you have students.
