CCSS Math Standard: 3.NBT.1

Use place value understanding and properties of operations to perform multi-digit arithmetic. Use place value understanding to round whole numbers to the nearest 10 or 100.

Rounding Numbers (But Not To 10)

What could we possibly do to make rounding more interesting for students who already get it? In this series, students consider how they might round to values other than "the nearest 10." How, for example, do we round to the nearest 9? 7? 15?
