What This Standard Means
What Students Need to Do
- Students use thousands, hundreds, tens, and ones to decide which whole number is greater or less. They locate numbers on scaled number lines and arrange sets from least to greatest or greatest to least.
What Mastery Looks Like
- Students compare numbers by checking digits from the greatest place value to the least. They place numbers accurately between labeled benchmarks and explain their order using place value or number line position.
Common Misconceptions
- Students may compare from the ones place or focus on the largest-looking digit. They may treat 10,000 as smaller than 9,999 because it contains zeros. On number lines, they often ignore the scale and space numbers evenly.
How to Assess It
- Give students a number line from 0 to 10,000. Ask them to plot 2,450, 3,700, and 9,250, then order the numbers and write two comparisons using symbols.
