Fraction Tiles

Fraction Tiles, A Manipulative Fraction Program by Lee Jenkins and Peggy McLean copyright 1972 Activity Resources Company, Inc. ISBN 0-918932-17-3 I found this used at Bibliomania in Tulsa. It has a teacher's book and two student books. It teaches from very simple to Multiplication and Division of mixed numbers. It has tiles from a whole to sixteenths. The tiles are heavier plastic pieces. There are other square Fraction tiles that teach the same concepts. I need this because fraction problems do not stop at 1/6 and are not always round.
