I added the “function diagram dance” activity to the Function Diagrams main page. I also added to that same page a list of the function diagram lessons in Algebra: Themes, Tools, Concepts (ATTC). Those sometimes duplicate, sometimes complement the other function diagram material on the Web site.
I added an “index of selected topics and tools” in ATTC (taken from the back of the Teacher’s Edition.) This is useful because the book is not primarily organized by topics, so it can be difficult to find some things.
Speaking of indexing ATTC: a correspondent asked for an index of ATTC lessons that use the 3D Lab Gear blocks. Compiling this is on my to-do list, but it seems less urgent now that the 3D blocks are no longer available for purchase.
