Comparing Numbers

This item has no instructions

Learning goal

I can compare two numbers using >, < and =.

What words come to mind when you compare numbers?

Use this to surface prior knowledge such as bigger, smaller, same, symbols, tens, or ones. Invite a few students to explain their words before teaching begins.

Mother Used Eggs

  • Yesterday: 20 eggs

  • Today: 15 eggs

  • We compare 20 and 15 to see which is greater.

The story context comes directly from the prompt. If needed, clarify that we are comparing the numbers of eggs used on two different days.

Compare the Tens First

  • 20 has 2 tens

  • 15 has 1 ten and 5 ones

  • Since 2 tens is more than 1 ten, 20 is greater than 15

Emphasise place value. Students do not need to compare the ones once they see that 2 tens is greater than 1 ten.

Greater Than

We say: 20 is greater than 15


We write: 20 > 15

Read the sentence aloud and point to the symbol. Keep the language exact: 'greater than'.

Which Day Had More?

Because 20 > 15, mother used more eggs yesterday than today.

Connect the comparison back to the real-life example so students see why comparing numbers matters.

When did mother use more eggs?

A

today

B

yesterday

C

same day

D

next day

Checks understanding of the story example: 20 eggs yesterday and 15 today, so yesterday is the correct answer.

Complete the comparison

Mother used 20 eggs yesterday and 15 eggs today. Since 2 tens is more than 1 ten, 20 is greater than 15. We write it as >.

20
15
greater than
>
10
25
less than
<
=

This echoes the exact phrasing from the first teaching block and reinforces both place value and symbol use.

Comparison Symbols

Greater than and less than

Equal to

= means equal to


It shows the numbers are the same.

> means greater than


< means less than

Keep all three symbols together here so students can contrast their meanings clearly.

Example: Greater Than

32 is greater than 23


32 > 23

If helpful, mention that 32 has 3 tens while 23 has 2 tens.

Example: Less Than

24 is less than 56


24 < 56

Point out that 2 tens is less than 5 tens, so 24 is less than 56.

Example: Equal To

45 is equal to 45


45 = 45

Stress that equal means exactly the same number, not just close.

Which number sentence is correct?

A

45 < 45

B

24 = 56

C

32 > 23

D

20 < 15

Distractors come from the examples on the slides but use the wrong symbol, so students must match number meaning to symbol meaning.

Finish the symbols paragraph

The symbol > means greater than, and the symbol < means less than. The symbol = means equal to, so 45 = 45.

>
<
=
=
greater than
less than
23
56

All blanks are load-bearing symbols from the second teaching block. Students connect symbol names to the worked examples.

What is one thing you learned today?

Expected reflection points: students may mention learning what >, <, and = mean, comparing tens first, or deciding which number is greater.

What helped you understand best?

Expected reflection points: students may say the examples, the egg story, or comparing tens helped them understand.
