We received Building Thinking Skills Level 2 for Grades 4-6. Unfortunately most of this book was much too easy for my "Gr. 4" aged son and I believe that much of it would be rather boring for the average student. In the front of the book there is work on identifying shapes and describing which ones are in front and behind, concepts which my almost-5-year-old has no problem with. However, having worked with a child who was in Gr. 4 in the past and needed some remedial work, I believe this would be a fantastic resource for students working below grade level, or having trouble with logical thought. Towards the back of the book is some of the wonderful content from the "Mind Bender" series. Cost on their website is $29.99 US or check out your favourite Homeschooling Supply Store online as these are popular books.
