Reflection: Shared Expectations Building Shapes- Review of 2D Shapes - Section 2: Presentation of Lesson


In our classroom, one of our rules is Be Respectful.  We spend a lot of time learning what that means and what it looks like.  We talk about respecting materials and one of our big discussions is about not breaking crayons and pencils on purpose.  Because of this, some students really struggled with making a rectangle.  They saw other students break the toothpicks, but they wanted to "respect the materials" and not break them.  I love that the students want to follows the rules!  After I let everyone know that it was okay to break the toothpicks (if it was needed for your shape), everyone was able to correctly build a rectangle.
