Often we can create Montessori style activities using materials we already have in our home. This one is super simple but really engaging. If I want to create a new activity for Otto I will think about what he likes doing and have a look around the house to see what I can find.
Otto is currently loving his open close tray so why not add an activity which involves matching lids to their containers. I love this one (above and below) as the jars are exactly the same except for their size. They are glass so he knows he needs to handle them gently. The control of error is that only the correct lid will fit. At almost 15 months it's not too hard and not too easy.
I've previously used this one (below) with Otis. Again there are three containers in different sizes. This one is a little harder as the lids are more difficult to put on and take off.
All this activity requires is three (or more for an older child) containers with lids, in different sizes. The lids should be relatively easy for the child to get on and off. A quick look around the kitchen and I hope most families would be able to find something suitable to use.
If the activity engages the child I am pretty happy. Here Otto is learning about visual discrimination. He is also developing coordination, hand and arm strength and concentration. With the glass jars he is also refining some of his movements to make as less noise as possible.
Above is Otto's open and close tray. I've recently reduced the number of items in it. He has a zipper pouch, flip top tin, a simple screw top round tin and screw top jar. The best thing about activities like this is they are entirely developmentally appropriate and use materials we already have at home.
