Thus, our execution of the standard algorithm to compute 25 × 63 requires four small multiplications and some additions. What about the distributive approach? 25 × 63 = 25 × (60 + 3) = 25 × 60 + 25 × ...

Consider the standard algorithm for multidigit addition and subtraction, which makes its appearance in Grade 4 of the Common Core math standards.

This study analyzed children's use of mental computation strategies and the standard algorithm on multi-digit subtractions. Fifty-eight Flemish 4th graders of varying mathematical achievement level ...

The present paper describes the success, the methods (mental, informal written, standard algorithm) and the strategies of informal written arithmetic to be observed when 300 elementary students worked ...

There is always more than one way to implement a standard algorithm. The examples used have been designed as revision materials that exemplify some of the ways to implement these algorithms. In ...
