Dr. Warren’s materials are fun, easy to use, and very effective with a wide-range of students struggling with a variety of critical thinking skills.  Her materials contain high-interest topics, presented in a kid-friendly manner, and capture the essence of a variety of fundamental thinking, reasoning, and learning skills.  The elementary and middle school students find the content manageable, interesting, and engaging.  In fact, many students look forward to doing work from Dr. Warren’s materials, which are subsequently used as “reinforcers” that the students can “earn” once they’ve completed their other work.  What a testament to the value of her materials.  I highly recommend Dr. Warren’s Good Sensory Learning Tools for parents and professionals who are looking for comprehensive, effective, creative, fun, and approachable materials to help build essential skills.  - Ilaina Blum, Santa Monica, CA
