One way that I plan to use digital videos in my classroom is to use teachertube. The two examples I found have to do with adding and subtracting fractions with unlike denominators because this is something that my students (4th/5th graders) struggle. I have already taught this skill. My students will use this to review the skill then try some problems on thier own. These would be skills that they would use to review during math intervention time so that each student is working on a skill that they struggled with when I taught the skill. I choose these skills base on how they did when the distirct assessed them through a scrimmage or a diagnostic. A problem that may a rise while doing this is the students may not pay attention during the review lesson. A second problem is that the computer may not allow teachertube to be used. The way around these are an informal assessment over what was reviewed for the studnets. Acess not allowed to teachertube can be fixed is talking to the IT department to allow acess to the sight.
Here are some examples of teachertubes to help review a skill.
