Lab Gear Activities for Algebra 1 and the 3D Lab Gear are no longer available from Creative Publications / McGraw-Hill. Moreover, they have redesigned their Web site, and all the URLs have changed.
Pentomino Activities, Lessons, and Puzzles is going out of print, but is still available.
Short run: I've updated my publications page, and the Lab Gear page, to reflect this.
Long run: I'm looking into ways to make the binders available again. If I can't find a publisher, then I'll post them on my Web site. Stay tuned!
