Use this "Just a dot, not a lot" template to help teach your students the proper way to use a bottle of glue.
Students can turn it into a beautiful mosaic. Just print on any color paper you'd like (I chose black) It is tougher to see the dots on black paper, but the black sure makes the bright colors pop. I trim off any excess and save the scraps.
Students can tear their brightly colored papers or you can have them cut into 1"x1" squares.
Dots Not Lots
Literature recommendation: "Too Much Glue"
