Very good for Year 1 age group.Yet another great book from KUMON series. I got 2 of them for my twin 5yo daughters, who are about to start Year 1 in school. Overall most of the tasks were just right for them, with a few may be a little too stretching. What I liked most of this book is a good variety of problems. Each type of problems goes through 4-6 pages of progressive complexity. We normally went through them over 2 days. The girls were very interested most of the time and even asked for more.If you haven’t already I suggest you to start with this book first: Logic (Thinking Skills Workbooks) (Kumon Thinking Skills Workbooks) which is suitable for Reception-age children.
