Let me begin by explaining that I run a home daycare so it is just me and 6 kids ranging in age from 20 months to 4 years old so I'm trying to meet a range of needs. I like having a sensory table for the kids, but I have a couple who still do not follow the rules for using the table: 1. don't dump on the floor and 2. don't pour over other people. Because of this, I am hesitant to try things like flour, cornstarch, or any other substances that have the potential for making a serious mess especially if they're dumped over other's heads (their favorite thing to do unfortunately). I am trying to work with them on this by using items that are fun, but not sooo messy with the hope that I will be able to introduce more as time goes on. We used cheerios for the past couple weeks, and they loved it, but I'd like to try something new. I am hesitant to try beans or pom poms, or anything that might be a choking hazard since my youngest still puts things in her mouth. I thought of doing rice, but I am at a loss otherwise. Any ideas? Thanks!
