Closure and anticipatory set

After searching closure in teaching and various other combination of words that mean the same thing, I have come to the conclusion that closure in terms of a lesson plan is a reminder to the students of what they learned in the day while also wrapping it up while still being meaningful. My favorite site I found for this word was found here. I found numerous definitions and ways to go about wrapping up. This site wasn't bad either.

I know that in my art classroom (practicum) I implement exit slips that ask them a question regarding the topic we went over (or artist), so in their sketchbooks I have them write them down ans well as any questions they have. For a math class I too would make them have sketchbooks. But exit slips would differ a bit. I would have a problem like the ones we worked on in class and have them answer it as best they can, or I would have them make up a problem like the ones from the day's lessons and solve it like an answer key. I would then go over them and see if the students are really getting it. Its meaningful to their learning (they are teaching me) and serves as an assessment tool for me...where are they and are they getting it?

When I searched anticipatory set I found that the definition for me should be an exciting hook to get the students pumped which alludes to prior learning so new learning can be built upon it. I found these two sites helpful.

In terms of our lesson plan, the nest day's anticipatory set could say, Hey, remember when we went out and measured that tree? What else can we think of that is all around us that are triangles? This could then lead us to today's lesson which is built upon the understanding of yesterdays lesson.
