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.
