My daughter and son-in-law like to have something scripturally based to occupy the grandchildren during church services/activities when childcare is not provided. These things keep them quietly occupied and offer a teaching experiencce, too.
I bought this book with another order because of the reasonable price. My boys love to do hidden pictures. They are young and so I had to tell them what they were looking for in the picture and they found them pretty quickly. Which is why I believe a 7-12yr old would be bored with this item. If they are readingl they will be able to read the instructions and then find the 5 or less items hidden in each picture and then color.
