Montessori 3 part (or "nomenclature") cards are used to teach a child the names of the various parts of something, in this case a windmill. There are three cards for each part, a control card which has both the picture and the label, a card with only the picture and a card with only the label. The child’s job is to match the cards, (you can find more detailed instructions on how to give a 3 part card lesson when you search online). He learns the vocabulary of each part as he does this. Each part is isolated on its card by being colored in while everything else is left black and white. This takes away any and all distractions from learning the specific part as it is isolated.
Included parts are: Windmill, sails, cap, platform, tail, capstan wheel, doors, & windows.
Set includes colored cards which are ready to print and laminate. Also included is a page with blank windmills that you can photocopy for the children so they can color, label, and make their own 'Parts of a Windmill' books.
