Knobbed Cylinder aiming to refine the children’ precepion of dimension. Such as size, depth, etc.
There are four sets of knobbed cylinder which are deisnged into different grading of size/ depth. Througt putting the knobbed cylinders into the sockets the children can obtain the preception of dimension.
Unlike traditional way, when teachers introduced this kind of absract concept, most of them are using picture card or other daily objects which are not prefectly designed.
Also you will note that the each material is in single color/ attribute becasue Maria Montessori wanted to isolate the difficulites whenever introduce the concept.
This is the reason why her method can keep going on to this modern society.

This is the how we hold the knobbed cylinder. So another aims of working this material is helping the children develop their pencil grip.

此教具另一目的是幫助幼兒的小肌肉發展。
感官教具Knobbed Cylinder
主要讓孩子透過操作些教具可感受到面積, 容積; 大小，而不是傳統上的透過老師講學而獲得的知識。本人認為Dimension的概念十分抽象，所以很喜歡用Montessori的教具介紹這些抽象概念給孩子。
可能你也會留意到為什麼Montessori的教具為什麼這麼單一？跟其他在百貨公司所見到的玩具不一樣，其他的玩具好colorful也有不同的形狀等等。
大家要知道Montessori稱這些為教具(working material)而不是玩具(toys)，所以我們Montessori Teacher經常提醒小朋友”We are working with in not play with it.”
再者各教具有primary goal希望孩子透過操作而逹到教學目的。而Knobbed Cylinder的焦點就在Dimension而唔是顏色，所以不要批評說她的教具不吸引孩子。
-
當孩子掌握基本操作後，他們很喜歡自己探索(explore)，如圖。
-
One of the children putting the small knobbed cylinder into the biggest socket and said “It doesn’t fit, Ms angie” Then he similed and removed all the unfit knobbed cylinders put them into the right sockets.
-
The other children, she was very concentrated on examing whether the big cylinders can fit into the small sockets.
-
Lastly children can work with all sets of knobbed cylinder in one go.
