To write a number sentence representing a change on a number line, you can use an equation that shows the starting point, the change (addition or subtraction), and the endpoint, such as (3 + 2 = 5). To use a number line to represent a number sentence, you can visually mark the starting number, then draw an arrow to the right for addition or to the left for subtraction, reaching the endpoint. This illustrates the operation clearly, showing how the value changes along the line.
