Programa de Incentivos para Boa Higiene Oral

The jardin in my area is great about having the kids brush their teeth after lunch but it seems those lessons aren't being consistently continued at home.  Here's a simple project based on positive reinforcement to encourage thier parents to get involved.  It can be done pretty cheaply by substituting popcorn for drops and/or by limiting the time frame (3 months, 6 months etc) instead of the whole school year.
