Standard / Traditional Algorithm

Is the Standard / Traditional Algorithm “allowed” in classrooms?

Absolutely!  Beginning in Grade 2, students are required to investigate the standard / traditional algorithm.  However, whether they choose to use it as one of their strategies depends on if it is an “appropriate and efficient strategy that they understand.”  (Alberta Education, 2016)

Alberta Education has provided examples of Alberta’s Standard / Traditional Algorithm.

Please be cognizant of the fact that some students who immigrated to Canada may have learned a different Standard / Traditional Algorithm in their schooling.
