Construct
simple selfchecking math
devices.
Cut
pieces of cardboard 25 cm ( 10")
long and 10 cm (4") wide.
Notch
both edges at 1.25 cm (1/2") intervals.
Print
20 multiplication and division
facts near the notches on one side; the answers, randomIy, on the other.
Working
independently, children stretch
rubber bands across the notches that connect the facts and answers.
The
device becomes selfchecking when
you draw tines on the back of the cardboard connecting the appropriate
notches.
If
rubber bands cover all lines, the
students know their answers are correct.
PS: Consider doing more fun printable
math activities.
