## Reflection: Checks for Understanding Rational or Irrational (Day 1 of 2) - Section 2: New Info/Application

I used this particular venn diagram to compare and contrast groups of numbers. After all, graphic organizers are a way of visually organizing ideas and relationships. However, venn diagrams can be a formative assessment tool because they not only can provide information on where students stand, but they also lead to discussion among students and between the students and the teacher. But before I use a venn diagram as an assessment I make sure that my students are familiar with these. Including a venn diagram on an exam without estimating previous student exposure to them, will be a waste.  If I plan to inlude any on an upcoming quiz or test, I make sure to use them and/or help students design their own, in lessons leading to those exams.
