Stepping Along

Overview

In this lesson (Lesson 6 of 15) students practise placing numbers on a fully labelled number line. They begin to understand that numbers go in order and that moving right generally means “bigger”.

Learning intentions

• WALT place numbers on a fully labelled number line.
• WALT describe what changes when we move left or right on the number line.
• WALT compare which number comes before or after another number.
• WALT use number line language (before, after, next, bigger, smaller).

Success criteria

• I can find a number on the line and place the correct marker.
• I can tell which number is before and which is after another number.
• I can explain whether moving to the right makes numbers bigger or smaller.
• I can check my work by matching my marker to the label.

Curriculum links

• Mathematics and Statistics — Mathsteasers: challenge through alignment and deeper understanding for advanced learners while still building foundational thinking.
• Number knowledge: ordering numbers and understanding the structure of number lines through meaningful representation.

Lesson structure (45 minutes)

1. 0–5 min · Welcome and hook. Teacher shows a large fully labelled number line on the board (e.g., 0 to 10) and says, “Where would 0 be? Where would 10 be?” Students do quick whole-group responses with hands/gestures.
2. 5–12 min · Model: what the line means. Teacher points to labels and moves a pointer from left to right: “This comes before… this comes next… this is after.” Teacher models placing two number cards (e.g., 3 and 7) by aligning each card exactly with the matching label while narrating magnitude: “Right means bigger.” Students watch and repeat key sentence frames: “___ is before ” and “ is bigger than ___.”
3. 12–22 min · Guided practice: place the markers. Teacher gives each student a small laminated number line (0–10) and three number cards, plus counters/marker stickers. Teacher calls one number at a time (e.g., “Find 5, place it on the line”). Students work one card at a time, then check by pointing to the label.
4. 22–30 min · Pair talk: order games. Teacher chooses two numbers from the set on the board (e.g., 2 and 9) and asks: “Which number comes first? How can you tell?” Students turn-and-talk, then share one idea to the class. Teacher uses prompts: “Point to where 2 is. Now point to where 9 is.” Students then complete a quick “Before/After” task with two cards: place both cards on their line and say: “___ is before ___.”
5. 30–40 min · Independent task: find and justify. Teacher hands out a short worksheet or cut-and-place sheet with 4–6 prompts, all using a fully labelled number line. Examples:

• “Place the counter on 4.”
• “Draw an arrow from 6 to the next number.” (Students draw on the line from 6 to 7.)
• “Circle the number that comes after 8.” Students complete quietly, using a final self-check: “Did my marker match the label?”

6. 40–45 min · Exit check: one-minute number line. Teacher selects one number (e.g., 6) and asks each student to respond: “Tell me where it goes and one thing that is bigger than it.” Students point to the location on their number line and answer.

Resources

• Large classroom number line (fully labelled) 0–10
• Individual laminated number line cards for each student (0–10)
• Number cards (0–10) and counters/marker stickers
• Pointer or flyswatter-style pointer
• Sentence starters on cards: “___ is before ”, “ comes after ___”, “Bigger numbers are to the right”
• Short worksheet or cut-and-place sheet with fully labelled number line prompts
• Quiet table mats for work area organisation

Assessment

• Observation during guided practice: correct placement and use of “before/after/next”.
• Check for understanding in pair talk: students can justify direction (right = bigger) using gestures or words.
• Exit check: each student points to a given number and states a bigger number (or identifies what comes next).

Differentiation

• Support: provide a word bank and sentence starters; allow students to use finger-pointing along the line during tasks; reduce prompts to 3–4 if needed while still requiring correct matching to labels.
• Targeted prompts: “Show me the label for this number” and “Which way do we move for a bigger number?”
• Extension: for students ready, include prompts like “Put 3 between 2 and 4” (still on a fully labelled line) or “Place the numbers in order from smallest to biggest: 2, 6, 9.”
• EAL/SEN considerations: keep language consistent, repeat “before/after/next” and model movements (left/right) so students rely on both words and physical pointing.
