Sliders
 |
Slider cards give the students practice with missing numbers. The paper slides are made out of construction paper. Wrap them around the fact card and tape on the back. Make sure you plan to size the sliders correctly for the size of your print. The slides should just cover 1 number. They can even cover the + or - sign. Students figure out the number that is covered by the slide. They check themselves by moving the slide.
Make a stack of slide cards for each of your tubs. You can refer to the Study Booklet to help you or a volunteer make the cards.
