See-N-Read is actually a very simple, inexpensive product that can help with tracking issues while reading. The basic product is a sturdy piece of translucent gray plastic with one clear, transparent line to hold on the page of a book as you read. It is 3 inches tall, and available in widths of 5.5 inches or 8.5 inches. I tried to get my children to use it as they read, but they didn't care to be bothered with it. If you have a child who likes (or needs) to track with his finger as he reads, this would probably be a great tool.
Another similar product is the MemoryMark, which is identical to the See-N-Read except that the window is actually cut out of the plastic. This offers a handy way to highlight passages in books as you read. I would have loved that in college! See-N-Read also offers a similar tool for reading on the computer: eSee-N-Read. Visit their website for a free 7-day trial to see if that would be something that would be helpful to you.
The See-N-Read and Memorymark products are available in single packs up to classroom packs of 25 and range in price from $2.99 for a single book size tool to $69.99 for a pack of 25 document size tools. The downloadable eSee-N-Read is priced at $29.99 for a download that can be used on a single computer, $69.99 for a three computer download or $99.99 for a five computer download. I received free samples of this product in exchange for my review as a member of the TOS Crew.
