## Reflection: Checks for Understanding Domain and Range of Graphs Using Interval Notation - Section 3: Independent Practice

Using a spreadsheet daily has became a part of my classroom culture.  It is a way for me to quickly assess and remember which students need immediate feedback on specific tasks. I provide feedback within the lesson if time permits. If not, then I take that feedback and conference with them the following day if possible.  With the Common Core, much of my time is spent lesson planning, and this method allows me to provide immediate feedback without so much grading.

As teachers, we have to purposely plan to fit in time to provide timely feedback, and it difficult. I try to select one item in the lesson to assess daily that is quick but assesses the learning of the objective.

The conferencing lets the students know that I care, and can immediately help them to meet the standards that they need to be meeting.  This helps provide my students with differentiated support to meet the learning objectives.

# Domain and Range of Graphs Using Interval Notation

Unit 1: Introduction to Functions
Lesson 5 of 13

## Big Idea: To have a deeper understanding of interval notation from inequalities and how the square bracket includes the number and the parentheses does not include it.
