This packet provides practice in working with mixed numbers, with emphasis placed upon subtraction. The exercises correlate with the material on fractional numbers presented in basic middle grade mathematics texts. The pages are presented in a suggested order, but may be used in any order which best meets the child's needs. Parents who wish their children to have practice in mathematics skills will find this packet as helpful as classroom teachers will find it. The exercises are presented so that a child can work with a minimum of supervision. Answers are included.
