This vocabulary idea is called Classifying to Practice. This idea can be used with any student expectation that requires classification and that’s A LOT of SEs. This blog post is about how I used the classifying to practice strategy to reinforce reflection and refraction with my students.
After reviewing what reflection and refraction are, students walked around and sorted items on a chart as primarily reflecting or refracting light.
After classifying the objects on the T-chart, we took the activity to the next level. Students determined similarities or things that the items that reflect light tend to have in common (like that they are opaque) and the characteristics that the items that refract light tend to have in common like that they are transparent. Then, they wrote a statement about the main differences between reflection and refraction.
