Montessori Hierarchy Of Number Material

I recently got this wonderful material made for my class. This material provides children with a concrete representation of the quantities of numbers 1 through to 1,000,000. The familiarity of the colour coding and material, really supports each child to develop an understanding of the sizes of the large numbers compared to units.

 I used a large 50cm x 50cm x 50cm card board box for my million cube. We spray painted in it green. A grandfather of one of my students made the other pieces in wood. 

Here the million, thousand and unit cubes are stacked for comparison.

Here the hundred and hundred thousand squares are stacked.

My class had a lot of fun comparing the pieces and labelling with numerals. Next week I will be presenting another lesson which follows on from this and helps the children develop an understanding of numbers over a million.
