I am still trying to wrap my head around the concept of low-tech, mid-tech, and high-tech. It can become a bit overwhelming, especially if you aren't as tech savvy. In regards to math, low-tech would more and likely be using items any classroom teacher using good practices in math would be manipulatives, laminated addition and multiplication tables, and large calculators with oversized buttons. I know for all the students in my class, I laminate a copy of the number grid 0-100 and tape it on their desk. I also laminate the number line from 1-30, as well as shapes, money, and color chart so that they always have these tools readily available at their desks.
Mid-tech adaptations would include, the "coin-abacus" and "coin-u-later" which contain keys that are shaped and sized just like coins. These can be used to teach basic money skills. Some other low-tech adaptations are talking calculators, and fraction rubber stamps. See 'n' Solve calculators show the entire problem on the screen so students are able to see their work.
These technologies look useful for all ages. The see n solve calculators to me would have been more helpful when I was younger. I would use some of these in my class to help students understand their grades. Students would be able to see and understand all the numbers in their scores.
