By moving the beads on the multi base abacus, children get their first experience of basic mathematical notions.
Thanks to the beads and rods, children can enjoy a number of games and perform a series of operations which help them:
- recognise the quantitative differences between numbers
- understand the meaning of cardinal numbers
- perform basic mathematical operations
- perform basic seriations which, when graded, help explain the meaning of ordinal numbers.
