About number lines, integers and subtraction
🎯SAMPLE LEARNING GOALS :
•Calculate the difference between two integers using subtraction.
•Represent subtraction of integers as the distance between integers.
•Reason about subtraction of integers in terms of number-locations and directed distances.
•Show that the distance between two integers on the number line is the absolute value of their difference.
•Recognize and generate equivalence classes of integer differences (e.g., 5 – 2 = 6 – 3).
