KWC charts help students analyze and solve story problems. This product includes instructions and ideas for use, as well as a week's worth of problems that increase in difficulty. Pencil Problems 1-5 are multiple-step double-digit addition and subtraction problems. Each day's Pencil Problem page contains one problem and a chart to help solve it. The aim is to work on fewer problems, in greater depth. These KWC charts help students find entry points into discussion of the problem.
