Reflection: High Expectations Making 11 to 19 - Section 5: Closure


Common Core standards are all about rigor. Having kids perform or parrot tasks is not good enough anymore. Kids need to be able to explain how and why they are doing what they do when reasoning mathematically. Start in kindergarten to get kids used to defending their thinking so that by the time the get into the higher grades they have a deep understanding of what they are doing throughout the steps in a process.
