Literacy Raz Kids: This is an online resource where it provides students with fiction and nonfiction books. This resource also provides students with their level books, to better suit their reading. This source reads the book outloud to the student, it allows them to read it on their own and then gives me a mini comprehension quiz. Raz Kids also provides books in Spanish for your English Language Learners.

PinkCatGames: This website is very engaging for students. It allows students to play literacy or math games. You can search whatever strategy your students need more practice on and have them play it. Students can work together to build a monster, feed a shark, do a relay race or spin a wheel as they practice their skill.
