Learning Objectives
Indicator: B3.3.2.1.1 - Represent whole numbers as distances from any given location on a number line.
By the end of the lesson, learners can:
- draw a number line and locate whole numbers as points on it.
- measure the distance between any two points on a number line by counting unit intervals.
- explain that the length of an object (such as a rod) does not change, regardless of where it is placed on the number line.
- represent a given whole number as a distance from a chosen starting point on the number line.
- justify their answers by counting intervals and comparing lengths.
