Reflection: Lesson Planning Triangle Types - Section 1: Opener


Foldables are a motivational learning tool.  Students love using foldables to display, practice, and master new vocabulary.  It is also a great instructional tool because it is a way to quickly organize information into a student created resource.  The students show are able to show their ownership to the curriculum versus a teacher created worksheet.

My one caution about foldables is that if you have never done them with your class, start small.  The foldable in this lesson is quite easy for students to figure out how to do with little instruction.  

There are many more foldable ideas floating around (e.g., Pintrest) that are much more complicated.  If your students have no prior experience with foldables, doing a complex foldable might lend itself to spending more time on the folding than on creating and illustrating definitions.  Complex foldables are definitely doable but sometimes frustrating.  Again, start small with an easier one and work your way up to a more difficult one.
