Large Hierarchy Frame

The large hierarchy frame helps children to learn the common technique of multiplication; moreover, when multiplication with two digits is carried out, it can also be done without transcribing the partial results and adding the 2nd to the 1st partial product obtained on the frame. In this way, the child will directly transcribe the total product. With this loom we can also introduce the child to multiplication by 10, by 100, by 1,000 because the child can easily understand that every time we multiply by 10, 100, 1,000, we change the hierarchy, precisely because ours is a decimal system.

The loom of the great hierarchies, or loom of the 1,000,000, consists of a wooden frame holding seven parallel metal wires: two groups of three wires are recognisable and at the bottom, spaced out, is a last wire. The two groups of three wires each have the same colours: green, blue and red. The beads of the last thread are green. On the frame, on the right, is written
- on a white background, at 1 - 10 - 100, "simple";
- on a grey background, at 1,000 - 10,000 - 100,000, "of thousands;
- on a black background, at 1,000,000, "in millions".
On the left-hand side of the frame are
- on a white background, the symbols of the simple family 1 - 10 - 100;
- on a grey background, the symbols of the thousands family 1,000 - 10,000 - 100,000;
- on a black background, the symbol for units of a million 1,000,000.
