Identifying and classifying integers.











A particular category of numbers called integers includes the digits zero, as well as positive and negative numbers. We emphasize that the positive and negative signs on integers, as well as learning how to represent the positive and negative integers on the number line, are all things that our M1/2 students are already familiar with.
Having applied all these we can now imagine that for M1/2, classifying and recognizing numbers is simple. (T. Sheethal)
