## Reflection: Intervention and Extension Describe 2D Shapes - Section 3: Independent Practice

Most of my students were successful in producing high quality work in this lesson.  One way I ensured success was by allowing my lower students to use manipulatives - pattern blocks.  These seemed to help them in counting the number of sides and vertices on the shapes by providing them with a concrete example to help them in drawing the shape and actually touching the sides and vertices while counting them.  Eventually, I want them to be able to see the shape mentally and be able to come up with the sides and vertices without the manipulatives, but, for now, it's good to give them the support they need until they can make that mental leap.
