Reflection: Writing Across the Disciplines Partitioning Squares to create rectangles - Section 4: Independent Practice


During this lesson, students spend the guided practice time working on a cut and past project where they divide a square into equal rectangles.  The independent practice consists of reflection questions.  I think it's important for students to have time to reflect their work.  This reflection and writing time allows students to think deeply about what they produced.  This "think time" is necessary for students to internalize the mathematical importance of the project and to make connections between the concrete project (cutting a square to divide it into equal rectangles) to the more abstract skill of drawing lines to  divide a shape into equal rectangles.  

Almost all of my students made the shift to drawing lines very easily.  One or two of my students needed some extra support to understand how to divide a shape without cutting it up or folding it!  I was able to support these students during the independent practice and closing time while my other students reflected and shared their work with each other.
