I've done small sand paintings on heavy chipboard with kids ages 7 - 12.
Cardboard warps when you apply the glue.
I colored the sand in separate little containers with powdered
tempera--just mixed them together. The students filled in each area with
white glue and applied the colored sand with little plastic spoons over
each container. I had them use neutral sand for the background because it
was closer to Navaho painitngs, but also because putting this neutral color
on LAST covers up mess ups and doesn't bleed as much as the colored sand.
We did this activity outside on the lawn on a big sheet of plastic. Try to
use commercial sand if you can as its more uniform and doesn't smell! Good
