How to Decrease Mistakes in Algebra – Part 2

When I left off yesterday, I pointed out a certain kind of algebra expression that tends to lead students to make mistakes. It was an expression like this:

 8 – 2(3x – 7)

I pointed out that students often mistakenly combine the 8 and the 2, to get this:

=            6(3x – 7)

=            18x – 42

The theme of these posts is:  how to help students avoid mistakes in algebra.

No Mistakes
