    This is one of my daughters favorite work books. She loves the challenge of only being able to have the passage read one time (even tho we often have to go back and re read) the different levels and type of questions keep her engaged and thinking!

    The OLSAT prep book by Critical Thinking Company along with their other materials enabled my autistic son to score far above his peers on cognitive assessments. This helped him not only get his autism diagnosis official, but it kept him mainstreamed while addressing the areas he was far behind in through speech therapy and occupational therapy. I am beyond greatful.

    This was a great resource for my kindergartner to use and was helpful in working on logic and reasoning skills.

    Its laid out as 4 practice tests, but we just did 3-4 questions per day. My child thought they were fun and challenging. I thought it was great at introducing the importance of listening carefully, following directions, and attention to detail.

    Mind stretching

    Karolyn B.

    This book used alone, or as test prep, will stretch the brain. I found it especially helpful when she did another assessment that challenged her in similar ways.

    A Surprising Gem!

    Ellen P.

    I used this book for my daughter 2 years ago and I'm repurchasing for my son to use this year! A great way to get them used to that standardized testing format in a state where we're required to test yearly. My daughter called it her "bubble book" and loved when we'd do our 2-3 pages once a week.

    The book was a fun and easy way to practice reasoning. My daughter didnt find the questions to be too difficult and she liked the book.

    Quick and Easy way to start test prep

    Sally K.

    I do 2 questions a couple times a week with my 5YO. This is a very simple way to start preparing him for test taking. I have older kids so I know how important it is to start early just to get them comfortable with the format of test taking. My 5YO enjoys this time together and it takes maybe 3 minutes. I read the question aloud ONE TIME, then he points to the answer he thinks is best. This has been a great insight for us, and a good learning opportunity- I am starting to see how his brain works.

    Depends on your schooling style

    Allyson R.

    This is a good test prep book. If that is the route you are going for your home schooling then this is perfect. If you are more child led learning or learn through play, I don't really think this book is necessary. Yes there are some great critical thinking problems, but there are other activities and games we do that get my child thinking the same way. This really is a personal preference item.
