A few years ago, I had a great lesson on testing those props before presenting a lesson. I mean, what could wrong with candy as props, right?
The monthly theme in my class had been about grace. The classroom has been decorated like a candy shop and the opening activities had used sweets as props. This was part of the curriculum at http://whatisorange.org/252basics/.
The lesson called for inviting kids to come up and “test” candy for the rest of the class. The samples included some pretzel M & M’s, gummy candy, and Pop Rocks candy.
