What does the term decomposing numbers mean? I continue to encounter the term decomposing numbers in the state proficiency learning outcomes. I have not found it defined beyond the example 2+5 = 7 and 3+4= 7. Does it apply to operations besides addition? I would like a better understanding of this term to plan experiences for my students beyond memorizing number sentences.
