We compare the activity of young children using a microworld and a JavaScript relational calculator with the literature on children using traditional calculators. We describe how the children constructed different meanings for the equal sign in each setting. It appears that the nature of the meaning constructed is highly dependent on specificities of the task design and the tools available. In particular, the microworld offers the potential for children to adopt a meaning of equivalence for the equal sign.
