Let's Improve Our Math Facts! This package contains Study Sheets and Drills Sheets for facts involving addition, subtraction, multiplication and division. Our self-checking fold-back sheets can be laminated; they are self-checking for individual use and can also be used for home study of basic facts. Focusing on a specific operation, drills can be given daily until expected speed and accuracy level is attained. Drill sheets can be cut into strips when focusing on a specific group, e.g. facts of 8. You can also send drill sheets home for study and practice. Students can graph their individual results while they are striving to improve their own speed and score. With all of the information contained in this unit and hard work, your students will all become a "Math Whiz"!
