This is a fantastic book with single page worksheets that gradually get harder as the book progresses. This pattern is also present in the worksheet itself, where some basic reasoning skills (that are developed more in the Bond books) can be practiced. I felt that this book was good value for money. There is a lot more practice for the child than in some of the colourful, sticker filled books. I didn't find the lack of colour and stickers a problem. Each worksheet is short, and stickers can be bought if necessary. I highly rate the other books in this series too.
