This is a Quicktime movie that you may use on its own for counting practice or teaching tool. You may also embed it in your own slideshow or use on your website. This could be used on an interactive whiteboard or projected to use for a class. This shows the place value as a graph as the slides advance. The preview includes the whole slideshow as a small movie file. The full sized one is 1024 x 768 and is better quality than the preview.
