The standard
Use place value understanding to round whole numbers up to 1000 to the nearest 10 or 100.
Element 3.NR.1.3 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Numerical Reasoning strand. It sits under standard 3.NR.1: Use place value reasoning to represent, read, write, and compare numerical values up to 10,000 and round whole numbers up to 1,000.
What students practice
Students find a number on a number line and decide which ten or hundred is closer, then round the same numbers both ways on a third page. Halfway rounds up, and nothing goes past 1,000. The first three number lines on each page print their endpoints; the rest leave the endpoints for students to fill in.
Where to find it
Think: 234 is between 230 and 240. 4 ones is less than 5, so 230.
