This paper concerns the use of instruments in teaching and learn ing mathematics at primary and secondary school levels. It focuses on the introduction and use of the arithmet ical machine Zero+1, called pascaline, and its relationships with other instruments used by students to write numbers and make operations, as spike abacus or calculator. The analysis of three teaching experiments shows that the instruments are related with respect to their utilizat ion schemes, but also to their representations.
