## Reflection: Rigor Is the Sum Even or Odd? - Section 4: Independent Practice

The common core standard for this lesson states that students should be able to determine odd and even numbers between 1-20.  I have chosen to push the rigor in this lesson by allowing my medium and high level students to determine if numbers 1-100 are even or odd.  I chose to push my students in this way because they have developed a conceptual understanding of even and odd numbers and pushing them to think about whether larger numbers are even or odd is a natural extension of this understanding.  For my students who struggle to have a conceptual understanding, I work with them in group A and focus just on numbers 1-20.
