Three-Digit Recall

Overview

In this lesson, students revise how to recognise and read three-digit numbers and build them using place value (hundreds, tens, ones). Students complete short, hands-on activities to practise identifying three-digit numbers quickly and accurately.

Learning intentions

WALT: Review and revise three-digit numbers using place value.

• Students will identify three-digit numbers in different representations (numerals, number cards, and quick images).
• Students will explain what each digit means using hundreds, tens and ones language.
• Students will practise reading and pointing to hundreds, tens and ones in a three-digit number.

Success criteria

• I can identify whether a number is three-digit and read it correctly.
• I can show a three-digit number as hundreds, tens and ones using place value supports.
• I can match a three-digit numeral to the correct place value representation.
• I can use “hundreds, tens, ones” to describe what the digits mean.

Curriculum links

• Number and place value: representing, partitioning and describing three-digit numbers using hundreds, tens and ones.
• Number fluency: reading, writing and comparing whole numbers up to at least 999 (including identifying three-digit numbers).
• Mathematical reasoning: explaining choices and justifying answers using place value language.

Lesson structure (30 minutes)

1. 0–5 min | WALT hook: Number detectives

• Display 6 number cards (some two-digit, some three-digit, e.g., 47, 108, 235, 90, 610, 999). Students hold up one finger for “two-digit” and two fingers for “three-digit”, then read the three-digit ones as a class.
• Teacher prompt: “What tells you it is three-digit?” Repeat “hundreds, tens, ones”.

2. 5–12 min | Place value “build and read”

• Give each student (or pair) place value blocks or bundling materials: 10 tens rods, 100 flats, and loose ones (or coloured counters: hundreds=red, tens=blue, ones=green).
• Call out a number (e.g., 347). Students build it, then write the numeral and point to: “3 hundreds, 4 tens, 7 ones”. Repeat with 2–3 more numbers.
• Quick check: ask 3 students to show their number and explain using the stem “The number has __ hundreds, __ tens and __ ones.”

3. 12–18 min | Sort and justify

• Create three columns on the board: “Two-digit”, “Three-digit”, “Not sure”.
• In pairs, students receive 10 number cards and sort them. They must place at least two “explain” stickers on cards they are confident about.
• Teacher circulates, asking: “Is this three-digit? Why? Which digit shows the hundreds?”

4. 18–25 min | Rapid identification game (hands-on)

• Play “Grab the right representation”. Teacher shows a numeral on the screen/board (e.g., 268) and students must quickly pick the correct place value bundle cards from a tray (hundreds/tens/ones cards) or choose the correct block arrangement.
• Students show their answer using a quick hold-up: number numeral + place value pieces.
• Keep rounds short (about 30–40 seconds each) with 4–5 numbers, mixing easier (e.g., 305) and less-easy (e.g., 209, 990).

5. 25–30 min | Exit ticket: Prove it

• Students complete an exit task on a half sheet:
• Circle the three-digit numbers from a list of 8 (mixed two- and three-digit).
• Write one chosen three-digit number and draw/indicate hundreds, tens and ones (a simple sketch or place value boxes).
• Collect and scan for misconceptions about hundreds/tens/ones and missing digits.

Resources

• Number cards (two- and three-digit numerals)
• Place value materials (base-ten blocks, or bundled coloured counters)
• Place value record sheets with boxes labelled Hundreds / Tens / Ones
• Column sorting cards: Two-digit / Three-digit / Not sure
• “Explain” stickers or small tokens for justification
• Tray of matching representation cards (hundreds/tens/ones)
• Exit ticket half sheets and pencils
• Visual place value reference chart (hundreds/tens/ones) with colour coding

Assessment

• Teacher observation during “build and read” and the rapid identification game: check that students correctly separate hundreds, tens and ones.
• Exit ticket: identify three-digit numbers and accuracy of place value representation.
• Targeted questioning: “Which digit tells you it is three-digit?” and “What does this digit mean?”

Differentiation

• EALD support: use colour cues for place value (hundreds/tens/ones), provide sentence frames (“The number has __ hundreds…”) and allow pointing/gesture responses before full verbal answers.
• Neurodiversity support: short rounds, clear visual instructions, and predictable routines (hook → build → sort → game → exit). Offer movement breaks during the game.
• Support for students needing scaffolding: reduce the number of cards, include only numbers with no zeros first, and use base-ten materials throughout without forcing written notation until ready.
• Extension for advanced learners: give challenge cards where one digit is zero (e.g., 407, 520, 901). Ask them to explain what the zero means in the tens or ones place.

Extension (optional)

• Create a “Three-digit numbers we notice” poster for the next lesson: students select (or the teacher provides) examples from class resources (classroom labels, number lines, days on a calendar, page numbers) and write them as three-digit numerals with a small place value sketch showing hundreds, tens and ones.
