Reflection: Checks for Understanding Algebra: Solving Addition and Subtraction Equations - Section 3: Closure


The students did really well with this lesson.  They understood the concept of using the inverse operation to get the variable on the side alone.  One thing that I had to do with a few students was to remind them to check their answers.  I have found that once some students solve math problems, they go to the next problem without checking their work.  I will continue to have the students check over their work because they need to form a habit of doing it automatically.  This life skill will help them in the real-world on their jobs because they will need to make sure that they have completed their work correctly.
