Which CCSS alligned workbooks are best for 6th grade math?
Workbooks should build lessons and supporting problems in complexity as the units progress. There should be a plan. Many problems use area or circles or fraction reduction as required steps for completion before being taught that year. Workbook companies should be required to actually work out the problems with noted skills and strategies so teachers aren't having to continually throw out problems and look for others in the sequence of learning.
