Grade 2 — Represent whole numbers as lengths on a number line and find sums and differences on it.
A note on this mapping: The number-line objective lives in Measurement & Data in the Common Core, not in Number & Operations — an organisational quirk, not a different idea.
The skill that covers it
What a student should be able to do
- Compare two whole numbers using <, > and =.
- Order a set of whole numbers from least to greatest.
- Locate a number on a number line and name the number at a mark.
- Find the number that comes just before or just after a given number.
