My older 3 boys and myself were recently given the opportunity and pleasure to review 3 workbooks from by
The workbook contains only 14 problems to solve but it does have Examples and Answers in the back, which is helpful if you want to double check that it's being done correctly.
The workbook has 42 problems to solve. The back has Answers which are helpful to look at if you're unsure if it's being done correctly or not. The last couple of pages in the book also have a few sample activities from other Critical Thinking Workbooks.
The workbook contains 43 activities. The back of the book has the answers which is helpful if you're unsure if the activities are being done properly or not.
The workbook is very simple and black and white only. This can be an upside for some children and a downside for others. My son at this age would definitely have been a little more interested at first glance if there were some colors and graphics. After beginning the activities he was more interested. He was clearly satisfied when he successfully completed them, which was nice to see. As with the other 2 books, I would like to see some diversity in the types of Deductive Thinking problems. A little diversity in the style of Deductive Thinking problems would make it feel much less repetitive. However, I do feel it was effective in it's intended purpose and would use again.
