Base-16 or Hexadecimal Blocks for Number Sense

####Base-16 or Hexadecimal Blocks for Number Sense The base-16 or hexadecimal (numeral) system is routinely used in computer science for convenience. Sixteen symbols are used: 0, 1, 2, ..., 9, A, B, C, D, E, F, where F(hex)=15(decimal)=1111(binary). The 16-cube is getting too big. But still it is fun, at least, visually, to see the meaning of 1 in a number (or rather numeral) such as 1000(H). Even though the unit cube is 8mm^3 and the 16-cube is 124mm^3, it takes about 100 hours, uses 0.6 kg of filament at 0% infill and 0.2mm resolution. This has to do with the design. I started with a unit cube and then built patterns around it in order to highlight the "units". To save filament, one would start with a big cube and then make marks around the cube. I have included an alternative based on such a design. Using 0% infill, it takes 9 hours and uses 37 meters of filament. Alternatively, please scale all the blocks down. 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 =16, unit = 8mm ^ 3): Please note that in a number(or rather 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 5^2 is much clearer. Unit (16^0=1) Ten (16^1) Hundred (16^2) Thousand (16^3) + Another Version that saves filament in a new design. Have fun!
