Question

A. using symbolic notation, then concrete materials, then applying to a real-world setting.
B. using concrete materials, then symbolic notation, then applying to a real world setting.
C. using concrete materials, then applying to a real-world setting, then symbolic notation.
D. applying to a real-world setting, then using concrete materials, then symbolic notation

Answer 1

The most appropriate sequence for introducing operations is:

B. using concrete materials, then symbolic notation, then applying to a real-world setting.

This approach helps students first understand the concepts through hands-on experiences with concrete materials, then transition to abstract representations with symbolic notation, and finally apply their understanding to real-world situations to see the relevance of what they have learned.
