Videos Online" and select the video)
 an online version of the FDRP casebook from the ERIC database
for Week 2:
 PSSM standards:
overview
 TEKS (see link in Standards section above):
don't try to read the whole thing, but get enough of a look
to develop an overall impression of what they're like and how
(and maybe why) they were written
 explore NCTM web page (see link in Govt/prof. orgs section above):
just have enough of a look to get an overall impression
(you can try their "About NCTM" link if you like)

 learner.org has two videos of children solving multidigit addition and subtraction
problems, one using colored chips, the other using DigiBlocks.
Note how the children realize that the numbers in these problems are
so large that they need some efficient grouping strategy, which leads
them to use groups of ten. This is the motivation for students to move
away from simple counting strategies toward placevaluebased computational
strategies.
