I use the Daily Spiral Review in the Envisions series, but I
don't use it as seatwork. I use it as part of BoardMath - a
program where you post daily problems for each of the strands
of math on your classroom whiteboard. The children
choral-read the problems, you walk them through solutions and
they do the problems showing their work and answers on
individual whiteboards. It is very effective, the students
are very engaged, and you can get a very quick read on what
your class has mastered and what needs more practice. You
can see it demonstrated on youtube or google the program.
I use the Daily Spiral Review from my textbook series, but
I've seen other teachers make up their own problems or use
the standardized test release questions they download online,
adjusting them as needed.
Hope that gives you a few ideas!
