Numbers and Dimensions
Lesson Page 1, Section 4
What you'll work on
Understand how the same number can be shown as a 0D point or on a 1D number line — and why each view is useful.
Big Idea for this lesson
Numbers can be shown in different ways. In 0D, a number is a single point — no length, no width. In 1D, the same number sits on a line, so we can see how it compares to other numbers.
