From the introduction we read: This beginning book on fractions is primarily intended for students in grades 4-6, but may be used wherever concrete models of fractions are needed top promote understanding and computational skill. No previous experience with Cuisenaire rods is assumed. Rod relationships and colors may be learned as students work on the meaning of fractions in the first few pages.
Meaning of fractions is emphasized throughout by constant reference to rod models, Initial work with equivalent fractions, inequalities, addition of fractions, and subtraction of fractions is all done with reference to a rod model and with not attempt to develop abstract procedures. Only after much experience with concrete models is the abstract procedure introduced.... After considerable experience with reds, many students will be able to add and subtract fractions in their heads without pencil and paper.
Most fractions in this book are proper fractions --only one page uses improper fractions.
50 page workbook, 48 pages of fraction problems with the answers in back.
