As I was reading the beginning of the 5 Practices book‚ I remembered certain times in my own education where math lessons seemed unconnected or had unclear goals. I don’t remember having to do nearly as much thinking as this book suggests‚ but the importance of pushing students in this direction is clearly needed in many of today’s classrooms. When faced with problems that don’t require much more than recalling an algorithm and using it repeatedly‚ it is clear that this is not “doing” mathematics

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise
