Reading for meaning is a very important everyday skill that students will be required to do for the rest of their lives. This lesson does a good job of providing students with the opportunity to practice this skill that sometimes is assumed. One thing that could be improved upon is making sure the texts chosen are interesting ones that students will enjoy and be excited to engage in. Additionally, one may want to provide a reading that can be listened to in case a student is visually impaired. Finally, I think this lesson has good ideas presented and the 4th graders will enjoy attempting to determine the better definitions.
Technology required is very easy to access for most schools.
