My Take
Overall, I liked this tool. Each text came with vocabulary and other enrichment activities that my students enjoyed. The texts discussed interesting topics that connected to other subjects being studied at the time. It did require a lot of copying and used a lot of paper, but you can also project the text if you didn't want to make copies.
How I Use It
I used Reading A-Z to provide leveled texts during small, focused, differentiated reading groups. Reading A-Z allows you to easily find texts based on a variety of topics. It makes reading differentiation much easier, as they have already determined the level of the text for you. It does cost to use the site, but a free trial is available as you or your school system decide if this program if right for you.
