Comparing numbers explained for parents (Australia)

Homework says which is greater? or use < or > and your child freezes - or guesses from how the digits look without matching the collections. Schools talk about more, less, the same, greater than, less than, and equal to long before the symbols stick. Same idea: decide which amount is larger, which is smaller, or whether they match. This guide unpacks comparing numbers for Australian parents - concrete match-and-compare first, spoken language before < > =, place-value for larger numbers, Prep–Year 2 mix-ups, and short home games.

It is a compare-amounts page, not an addition strategy. Starting from the larger addend when you add sits in bigger number first. Digits and tens sit in place value. Pairs that make ten sit in number bonds. Year maps: Prep–Year 2 maths.

The big idea: more, less, or the same

Comparing means deciding the relationship between two amounts (or two numbers that stand for amounts):

• More / greater than - this collection has extras after you match one-to-one.
• Less / less than - this collection runs out first when you match.
• The same / equal to - both match with none left over.

Example: 7 grapes and 5 grapes.

• Match grape to grape: five pairs, then two grapes left in the first pile.
• So 7 is more than 5 (and 5 is less than 7).

Example: 6 and 6.

• Match one-to-one: nothing left in either pile → they are the same / equal.

Say it aloud: "More, less, or the same?" That sentence is the heart of comparing. The symbols < > = are only a later shorthand for the same three ideas.

Underneath: trustworthy counting ("how many?") and subitising (seeing small groups without recounting) so the totals you compare are honest.

Australian Curriculum Mathematics (version 9) builds comparing, ordering and place-value reasoning across Foundation to Year 2 (Foundation–Year 2). Classroom labels vary (more/less, greater/less, compare, order); echo your child's teacher.

Concrete first: match-and-compare

Line them up. Put two piles of counters (or pasta, Lego, grapes) side by side. Child matches one from pile A to one from pile B until one pile runs out. Ask: leftover in A, leftover in B, or none? Name more, less, or the same.

Tower race. Build two towers with the same-size blocks. Which is taller? (Same height = equal.) Then count each tower to connect height to number.

Snack share check. "Do we both have the same number of crackers?" Match on the plate. Leftover crackers mean unequal shares - a gentle fairness story that is still comparing, not yet formal division.

Keep sessions under ten minutes. Celebrate the sentence ("seven is more than five because two were left over"), not only the label or the symbol.

Language before symbols: greater than, less than, equal to

Many Australian classrooms teach the words first:

• Greater than = more than
• Less than = fewer / smaller amount
• Equal to = the same amount

Only after the words feel steady do teachers introduce:

• > greater than (8 > 3)
• < less than (3 < 8)
• = equal to (6 = 6)

A common tip that helps some children: the open side of < or > "eats" the larger number (the "hungry crocodile"). Use it as a memory hook, not as the first explanation. Children who only know the crocodile often cannot explain why on a worksheet that asks for words or for a matching story.

Practice saying full sentences: "Eight is greater than three." Then write 8 > 3. Same idea, two jackets.

Not the same as bigger-number-first

Parents often hear "start with the bigger number" at homework time and wonder if that is comparing.

• Comparing asks: which amount is more / less / the same? (or later: write < > =).
• Bigger number first is an addition habit: when you add 3 + 8, hold 8 in your head and count on three more (9, 10, 11). You use "which is bigger?" as a step inside adding, not as the whole lesson.

This page owns comparing. The addition strategy page owns count-on-from-larger. Link them gently: comparing helps children spot the larger addend; bigger-number-first uses that spot to add efficiently. Different jobs.

Place value for larger numbers

Once children compare within 10 or 20 by matching, place value carries them further:

1. Compare tens first (47 vs 32: four tens beats three tens → 47 is greater).
2. If tens match, compare ones (47 vs 43: same tens; 7 ones > 3 ones).

That is why "look at the tens column" appears on Year 1–2 worksheets. Do not start there with Prep children who still wobble on matching small piles. Concrete match-and-compare first; digit columns later.

Teens need care: 19 vs 21 looks "close" in digits but matching or tens-first shows 21 is greater. Link lightly to teen structure if your child is still solidifying those names.

Year by year: where comparing shows up

Prep - after children can count a set and say how many (Prep maths, three counting skills), many classes compare small collections with more / less / the same. Symbols are light or absent. Ordering two or three numbers (smallest to largest) often begins here.

Year 1 - comparing and ordering within 20 (then beyond) becomes a regular checkpoint; spoken greater than / less than / equal to and then < > = appear; early place-value compare for two-digit numbers begins (Year 1 maths).

Year 2 - firmer place-value comparing for larger two-digit (and often three-digit) numbers; ordering sets; linking compare language to addition and difference stories ("how many more?") (Year 2 maths).

Common mix-ups (and kinder fixes)

Guessing from digit looks ("9 looks bigger than 12"). Fix: match objects or use tens/ones. Nine ones vs one ten and two ones - tens win.

Confusing comparing with bigger-number-first addition. Fix: ask "Are we deciding which pile is more, or are we adding?" Point to the right guide.

Only memorising the crocodile without words. Fix: ban symbols for a week. Insist on "greater than / less than / equal to" sentences. Reintroduce symbols as shorthand.

Thinking equal means "looks the same" (same colour counters) not "same number". Fix: match different objects (six red vs six blue). Equal is about how many, not appearance.

Mixing more/less with odd/even. Odd/even is about pairs and leftover (odd and even). Comparing is about which total is larger. Keep the jobs separate.

Racing to column compare before matching is steady. If 8 vs 5 still needs a full recount of both piles with no leftover story, stay concrete. Then offer tens-first as a check, not a first step.

Home games that do not feel like worksheets

Leftover match. Two handfuls of pegs. Match one-to-one. Name more, less, or equal. Repeat.

Number-card duel. Flip two cards (0–20). Child says which is greater and why (match story or tens/ones). Swap roles.

Tower equaliser. Build a tower of 7. Child builds one that is equal / greater by two / less by one. Count to check.

Symbol switch. Say a sentence ("nine is greater than four"). Child writes 9 > 4. Then reverse: show 5 < 8 and say the words.

Snack fairness. Plate two unequal snack piles. Child equalises by moving pieces - a compare-plus-adjust game.

Keep each game under ten minutes. Stop while it is still friendly.

A simple weekly home routine

1. Two minutes of match language - two small piles; match; say more, less, or the same.
2. Five minutes of one game - card duel, tower equaliser, or symbol switch.
3. Three minutes of a place-value link - for ready children, compare two two-digit numbers tens-first - see place value.

If nights fray, shorten further - see homework without tears.

Ask the teacher: "Do you introduce comparing with match-and-compare and more/less first, or with symbols early - and when do you bring in tens-first for two-digit numbers?" Matching language reduces crossed wires.

FAQ

Is comparing the same as bigger-number-first?

No. Comparing decides more / less / equal. Bigger-number-first is an addition move (hold the larger addend, count on the smaller). They share the idea of spotting which number is larger, but the goals differ (bigger number first).

Should we teach < > = before the words?

Usually not. Words first (greater than, less than, equal to), then symbols as shorthand. The "hungry crocodile" tip is fine after the meaning is clear.

How do we compare two-digit numbers?

Compare tens first; if tens match, compare ones. That rests on place value. For small numbers, keep matching objects.

Do we need special materials?

No. Counters, pasta, blocks, number cards, or snack pieces are enough.
