Clay due budget restraints in Kansas we will not purchase textbooks this year, which is fine with me, since I feel they are overrated. Using our state standards, of which we are guided by on our state assessments, I have talked two teachers into doing our own textbooks using Brokenworld as our model. Would Core Knowledge be something we should look at as a supplement for our curriculum and standards? Can we ask for guidance from you in this endeavor? I am going to purchase several books on blogging and wikispaces for these teachers to use. Any suggestions?
