enough.
To those who have used algebra tiles with their students (Suzanne?), how much
time do you spend with them and how long does it take students to catch on?

Eric,
I'm glad you found these. I hadn't seen them before.
As someone who has always found algebra tiles to be harder than algebra, I found
the "activities" that just tell you to illustrate a property not very helpful.
On the other hand, some people find these visualizing tools are a breakthrough
in terms of understanding what's going on, and perhaps just playing with them in
a taskoriented way can bring that about. But I think some examples would
help.
