Do you know why your students are having a problem with a particular number family or procedure?

  • Are they not sure of what number comes next or before?
  • Can they recite memorized sequences stating that 23 follows 22, but they don't know what follows 32 or 42?
  • Can they accurately construct a problem on a numberline or graphic? Do they know what the problem means?
  • At each level of development, can they think mathematically? Do they recognize that
    8 + 3 is like 8 + 2 + 1, which is like 10 + 1?
  • Do they have a mental image that supports their understanding of why 7 + 1 and 1 + 7 both equal 8?

This volume helps you identify conceptual and procedural problems and address them.

Here are some sample pages from the book.

* Built on the documented success of the 1999 California State adopted The Best Stuff for Adding, and Subtracting in raising student achievement scores
