Cylinders Block Step - Single Size

One of the basic sense aids includes four wooden blocks that are graded according to their difficulty (from block 1 to block 4). In each block there are 10 rollers with handles.

From classical rollers, the tool is different in wood and processing.

Rollers with handles are a very popular tool among children. Children have been working with them for two years. Older children work with them very much in the group and often with all the blocks at a time. The aid develops primarily visual perception, but as with every sensory aid, the child uses and develops all senses. Numerous mathematical concepts are incorporated into the aid and when working with it, the child is also preparing for writing - work from left to right, pinch grip, wrist release,

And of course, the child adopts new concepts through the guide (teacher / parent): thick - thin, wide - narrow, tall - low, large - small.

Block 1: Rollers change in one dimension. The diameter decreases by 5 cm evenly by ½ cm, the height remains the same. The child learns the concepts when working with them: thick - thin, wide - narrow.

Block 2: The rollers change in two dimensions. The diameter decreases by 5 cm evenly by ½ cm. The height decreases steadily by 5 cm by ½ cm. The child learns the concepts when working with them: high - low, large - small.

Block 3: The rollers change in two dimensions. The diameter grows evenly from ½ cm to 5cm. The height decreases steadily by 5 cm by ½ cm. The child learns the concepts when working with them: high - low, wide - narrow.

Block 4: The rollers change in one dimension. The diameter of the rollers is 2 cm and remains the same. The height is evenly reduced from 5 cm to ½ cm. The child acquires the concepts: high - low.

How to work with:

We invite the child to work "Would you like to show how it works with Handles with handles? We show you how the roller block is worn.We hold the block with both hands always behind the outer end.We work from left to right, dominant hand we roll rollers behind handle (3 fingers ) And put them on the rug before the block.When we remove all the rollers, we look at the empty block with the holes for the rollers.We start to rewind, again from the left to the right.We roll the handles into the non-dominating hand and the fingers of the dominant hand order the lower edge of the roller, (In block 4 we examine the depth of the hole), then insert the roller into the correct hole, so put all rollers back into the block.

Already during the demonstration we involve the child. It is recommended that the child work first with each block separately. The longer the child is working with the rollers, the improvement improves - his visual perception is softer.

Next steps of the lesson: First, we show the child block 1. Later, the child can work with Blocks 2 and 3. Finally, we include block 4 - the child must compare the height of the roller (clearly visible) with the depth of the holes (which is not clearly visible). This requires a certain experience the child gets on blocks 1-3. When we roll the roller, we place the carpet in a scatter. Work with more blocks at the same time, first two, then three and finally four. When working with four blocks, enter the tasks: "Find two identical rollers . " "Find the lowest rollers." "Find the thinner rollers." "Which is the hardest?" Etc .. Working with blindfolds gradually at one, two, three and four blocks at the same time.Checking the accuracy: by sight, feeling Specific vocabulary: thinner, thickest, heaviest, lowest, thin, thinner, heavier, lower ... etc.
