These were used in my math education. Theoretically, it's a good way to explain base ten but I don't think it helped me much.
Oddly enough dominoes somehow lodged themselves in my mind though, I still picture the number ten as two sets of five dots arranged.
- gohrt 11y agohow is "base 10" related to these rods?
- kenjackson 11y agoThe rods often (typically?) have 10 units on them.
- olefoo 11y agoMore than that, they are 1cm^3 for the base unit and the orange rods are 10 cm's long. The precision is pretty good on the ones I had growing up. 10 of the long rods fit a meter measuring stick to within the precision of the markings on the ruler. If you wanted to use them to teach continuous variables, it would be easy to do so by analogy using the volume of the numbers.
