Story Problem Videos

This link came from Dr. Nicki's blog.  I like the first few videos because it shows how to use  bar diagramming to introduce students to part-whole story problems, two step story problems, and comparing story problems.  Next year I want to make sure I teach my first graders how to solve story problems in a more systematic way using the types of problems that are outlined by CGI (Cognitively Guided Instruction).
