Comparing 3-Digit Numbers Worksheets

About this resource

A comparing-numbers kit for second grade (and a first-grade stretch): greater than, less than and

equal to, practiced five genuinely different ways with real 3-digit numbers (100–999 throughout),

plus the record-keeping a classroom or small group needs around it.

EVERYTHING INSIDE (24 pages)

• 8 Base-Ten Block Comparison items across 2 pages — two 3-digit numbers shown as hundreds flats,

tens rods and ones cubes, side by side; circle or write the symbol

• 12 Numeral Comparison items on 1 page — no pictures at all, the quick, abstract version
• 12 Ordering items across 2 pages — six triples least to greatest, six triples greatest to least
• 12 True or False items on 1 page — a printed number sentence; decide if it is correct
• 6 Word Problem items on 1 page — two invented people or groups, a 3-digit count of plain

countable things, who has more

• 3 answer keys, generated from the same numbers every worksheet uses
• 1 practice tracker (one student, five comparison formats), 1 progress snapshot (a bar graph

rolling the five scores into one picture), and 1 class grid (whole class), type-in or print

• 1 family update — a note home with blanks for the week's formats and the district's own wording
• 1 home practice page — a second, self-contained practice set for a family to use together, with

no school materials needed

• 1 filled example — an invented student, every number checked against its own table
• 1 phrase bank — progress-note, family-note, next-step and talk-first starters
• 1 binder cover with a spine label and six divider tabs
• Start Here, a how-it-works page, and a contents page that gives every page number

Every Number Is A Genuine 3-Digit Number

Every number in this file is checked at build time to fall between 100 and 999 — on the

worksheets, the answer keys, the filled example and the tracker. Nothing drifts to a 2-digit or

4-digit number anywhere.

Every Symbol, Order And Answer Computed, Never Typed

Every "greater than," "less than" or "equal to" in this file comes from comparing the two numbers

themselves in code. The ordering pages' correct order is Python's own sort on the same triples

printed. The true/false page's answer is the same comparison function checked against the symbol

actually printed — so some statements are deliberately false, not all true. The word problems'

"who has more" is the same function, applied to the two counts named in each story. There is no

second, hand-typed key anywhere in this file.

Five Ways To Compare

Base-ten blocks show two numbers as hundreds flats, tens rods and ones cubes — count each number's

blocks, then compare. Numeral comparison drops the picture. Ordering asks for three numbers at

once, in both directions. True or false flips the task around: is a finished statement correct?

Word problems ground the same comparison in a two-sentence story about an invented person or group.

Type In, Or Print

The name and date lines, the symbol lines, the ordering blanks, the tracker, the snapshot, the

class grid, the family update and the home page are type-in fields in any PDF reader; every block

and every number is always printed, never typed. This is a fillable PDF; it is not a Google

Slides, Google Docs or PowerPoint file.

Who This Is For

Second-grade classrooms (and first-grade classrooms ready for 3-digit numbers), self-contained and

resource rooms, and any small group working on comparing 3-digit numbers below or above grade

level.

What This Is, And What It Is Not

A comparing-3-digit-numbers practice set with the record-keeping around it. It is not a full math

curriculum, not an assessment, and not a claim about any student's age, grade level or rate of

progress. The tracker has a blank line for your own scoring criteria.
