# MAFS.3.NBT.1.1

Use place value understanding to round whole numbers to the nearest 10 or 100.
General Information
Subject Area: Mathematics
Domain-Subdomain: Number and Operations in Base Ten
Cluster: Level 1: Recall
Cluster: Use place value understanding and properties of operations to perform multi-digit arithmetic. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
