I have bought a few books on Montessori activities for children at home and this is my favourite. The publishing standard is really high: very well laid out, lots of pictures and diagrams, easy to follow instructions. The descriptions of how to present the activities to your child are very 'Montessori' without being excessively prescriptive. All the activities are easy to do at home and don't require any special equipment (there are sheets to copy in the back for a few items). There is a nice progression of activities e.g. from sorting opposites of rough and smooth to identifying different grades of rough and smooth. My mum is a qualified Montessori nursery teacher and also thinks the book is great!
