## Reflection: Developing a Conceptual Understanding Units of Mass - Section 4: Closure

Tools are very important when teaching for conceptual understanding.  In this lesson, the students were given the opportunity to use a balance scale to find the mass of an object.  I could have just shown the students pictures of the items and told the students that the eraser has more grams of mass than the paper clip.  I wanted my students to experience more!  Therefore, I gave them the hands-on experience of using a balance scale to measure the mass of the eraser.  This was a valuable experience for the students that they will remember.  If they see a question about grams and kilograms, the students will know that we use balance scales to weigh mass.  Plus, students love hands-on activities!
