You tube
You tube can be a power house of educational videos. I recommend previewing all videos ahead of time. All of the videos below are educational and kid/teacher approved.
TouchMath
TouchMath is a supplemental math curriculum that has been very effective with the students in our classroom. Although it can be a little confusing (what do all the dots mean?) this link will connect you to the TouchMath training videos. I highly recommend viewing the videos so you can help reinforce what we learn here at school.
