This book is great! On each page there is shown a theme: for example, the demolition site, the quarry, the forest, the farm ... the middle of the book there are all stickers that children can stick on each theme. there are lots of stickers to stick and under each sticker, we read the name of the construction machine (drilling machine, site dumpers, backhoe, dump truck, tractor ...). I learned vocabulary and my little 2 year old boy !!! I am delighted this. In addition, the child can then browse and completed his notebook and remember the name of every construction equipment. It's much better as fly sheets.
