####Base Seven Blocks for Number Sense The base in a positional value number system can be any natural number. Why not base 7? In reality, base-7 is rarely mentioned in a math textbook but is certainly possible. It would make it much easier to share things using seven-related schemes. Well, just for the fun of doing it, here is a set of base-7 blocks. The impact of these blocks depends on the way they are used to communicate and model mathematical practices. Of course, after Base^3, it is physically impossible to use blocks to show the meaning of a base in a positional value number system. Among the files are (Base =7, unit = 10mm ^ 3): ##### Please note that in a number (numeral) system other than base-ten, the words, ten, hundred, thousand, are now confusing, although some people do use them. A specific reference such as 7^2 is much clearer. 1. Unit (7^0=1) 2. Ten (7^1) 3. Hundred (7^2) 4. Thousand (7^3) + A different design that saves filament.
