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.
