What This Standard Means
What Students Need to Do
- Students compare up to three whole numbers through 999 and place them in increasing or decreasing order. They use hundreds, tens, and ones to compare numbers shown with objects, pictures, or numerals.
What Mastery Looks Like
- Students correctly order three numbers shown with numerals, drawings, or base-ten materials. They explain their order by comparing hundreds first, then tens, then ones.
Common Misconceptions
- Students may compare the ones digits first or choose the number containing the largest single digit. They may also reverse least-to-greatest and greatest-to-least order or misread a missing place as no value instead of zero.
How to Assess It
- Show 407, a base-ten drawing of 470, and 400 + 10 + 7. Ask students to order them both ways and circle the place compared first.
Lesson moves
Ways to Teach It
Give students base-ten blocks and three number cards, then have them build each number and arrange the models from least to greatest.
Ask students to explain in writing why 528 comes before 582 when both numbers have five hundreds.
Play an ordering race where pairs draw three number cards, arrange them both ways, and earn a point for each correct order.
Use three classroom supply prices under $999 and have students rank them from cheapest to most expensive, then reverse the order.
