The last three environments support the development of strategies for mental calculation of addition and subtraction with result less than 1000.

The practice in these environments allows students to have a concrete experience of the various steps involved in the strategies of mental calculation implemented by experienced people. Through the experience gained in these environments, students internalize these strategies and execute them mentally.
