First cut your paper plate to resemble a pie slice.
Now have children cover their entire piece completely with orange tissue paper squares. Set aside.
While they are working on that, cut some small squares out of your brown cardstock. This will be the "crust" of the piece.
Once your child is done completely covering the paper plate, staple the brown squares along the edge where the pie crust would be.
To finish off the Paper Plate Pumpkin Pie Slice, have your child glue/sprinkle the orange glitter on top of their piece to represent "the spice" for the pie and then glue their white pom poms in the center as well.
Then let it dry completely before displaying proudly!
