Teaching on topic: logarithms I arrived in a bad spot. I do not
think I properly lined up my ducks before reaching logarithms.
And now I’m sort of stuck. The book, my text, uses “inverse
functions” as the segue. And I’ve walked right up to that line,
and realized I would have preferred to approach from another
side. Blame the book. Blame the over-packed curriculum. Blame
the teacher’s poor planning (well, no, please don’t). I’m not so
wild about teaching at almost the same time as teaching what a
log is. But maybe I’m wrong. Could we introduce logs back when
we work with exponents in Algebra I? Probably too abstract? So
while I’m not so wild about where I’ve ended up, I’m not sure I
have or had a real alternative. I will use part of the idea from
Kate(t)’s neat intro log lesson. And I will make them look like
a puzzle. Students like puzzles. And I will separately and
carefully get them to graph and its inverse, without clearly
making the links. And if all goes well, one kid, then another,
will notice the link
