I saw your posting on the home page of Teachers Pay Teachers; so, I thought I would look at your freebie. Have you downloaded Really Rachel's pricing charts which are free here on TPT?
The average price is $.25 per page.
Here are a few other suggestions that might help you to better market your products. Add a cover page to every one of your products which can then be used as an attractive thumbnail to entice buyers even if that resource is only one page long. You are competing with over 35,000 sellers so you want your products to stand out. You might also add a second page which is a directions or suggestions page for the teacher. (How do use this? How? Etc.) List several ways you use this product in your classroom. Never assume that a buyer knows how, why, or when to use your product. Also, when needed, add an answer key.
Use the footer to put the copyright symbol, your name and date of creation on EVERY page. Here is how you do that. Use the insert and go to the right. You should see symbols there. Insert the copyright symbol, your name and date. It should look something like this: © V. Rauch (Scipi), 2011 Items, especially free ones, have been "stolen" from TPT and posted on other sites to be sold. You have to protect all of your creations. Also number your pages.
It is important that we see what others are doing; so, feel free to look at any or all of my freebies listed below to gather some ideas.
The best of luck as you sell on TPT!
