fair warning

If all goes as planned, I am going to begin working through the Unit 5 worksheets from the Arlington Algebra Project, as lgm suggested. Tonight.

I say 'fair warning' because there's no answer key.

instructional practice

I was looking for an old ktm post about Kumon this morning, and when I found it I rediscovered the concept of instructional practice, meaning practice that teaches.

I think that's probably what the Arlington Algebra Project's sections on probability provides.
