3-6
This is an individual exercise, which may be done either on the table with a table mat or on the floor on a floor mat. (Note: work cycle to be observed) This presentation can be carried out in 3 stages, advancing from one stage to the other as and when the child is competent enough. (Repeat the presentation for each of the 4 blocks of cylinders, advancing from Block 1 to Block 4 as and when the child is competent in each block.)
Return the block of cylinders to the shelves, holding the block with two hands at both ends.
Each cylinder has a correct socket. If the child incorrectly places a cylinder, then the exercise cannot be correctly completed.
The important objective is that the children should be able to use each cylinder block successfully and they must be allowed the time they need to achieve this. Seriation of several objects can be a difficult exercise for very young children - but the seriation of the cylinders is assisted by the Directress's demonstrations and by the fact that it is easy to see if a particular cylinder is in the wrong socket.
