Reflection: Homework Interval Notation - Section 6: Check for Understanding and Practice

Here is an example of student work.  The student did a good job annotating the page which helps me understand her reasoning. The student place a note (Union symbol?) on the page. By writing that note the student was able to ask a question of other students or myself before the work was turned in to be graded.

If you notice I only circled the errors on the page. One strategy I use on homework is to allow students to correct errors if the work is turned in on time. The errors can be fixed and turned in up to the day of the assessment. Many students take advantage of this strategy. Students will discuss with each other the problem. The students that correct their mistakes usually do better on their assessments.
