This book is lots of fun for kids to practice cutting & glueing. My 5 yr old son did it when he was 4 and is now doing it again. He can do it on his own now (with a glue stick.) The graphics & paper quality of this book is great. Keeps em busy!

The layout and the concepts of this book are excellent. The twenty assignments contain two different tasks--using scissors and assembling puzzles. However, I believe the recommended age is off especially assembling the puzzle part. I believe the appropriate age for this book is two-and-half to three-and-half. However, I wish Kumon would made a little more challenging by increasing to fifteen-piece puzzles or more. My daughter used to play with a fifty-piece puzzle when she was three. Her current challenge is one hundred-piece puzzle.

My Son is only 2.5 yrs old, but loves puzzles and also likes to use the glue and paste. Since it was too much for me to keep on buying wooden puzzles, I got this book even though the age range was different. He is enjoying them immensely (though I have to do the cutting for him).
Cons:
Since the puzzle pieces and the pieces in the solution page come numbered, with the first puzzle, he simply started matching the numbers and got it right in a sec! Since then I have him solve the puzzle outside on the table and then make him stick the pieces on the solution page. I feel this could have been avoided.
One improvement would be to make it spiral bound so that you dont have to hold the pages while the kid is working!

This is a nice book of jigsaw puzzles. There are 20 puzzles, and there are two pages for each puzzle. The first page has the colorful puzzle pieces that the child cuts apart. The second page is a guide that the child uses to assemble and paste the jigsaw pieces. The puzzles range from 4 to 12 pieces.

This is a fun book for children who like to keep their hands busy. Age range (4-6) is about right.
