Past to Future Timelines

Overview

In this lesson students continue “Tech Explorations: Past to Future” by creating a classroom technological timeline. In groups, learners compare technologies from earlier and later times, then present their ideas using simple chronological language.

Learning intentions

WALT create a timeline of technology by:

• WALT identify technologies used in different times (past and future ideas)
• WALT place technology events/items in order using “then/now/soon” or “past/next/future”
• WALT describe how a technology has changed and why it might be used

Success criteria

• I can sort technology cards into past, now, and future (or early/older and newer)
• I can place cards in the correct order on a timeline
• I can explain what changed about the technology using at least one reason (e.g., faster, safer, easier)
• I can work respectfully in a group to share our findings

Curriculum links

• Technology: Designing and Developing Digital/Non-digital Outcomes — developing ideas and producing a simple outcome (a timeline)
• Technology: Knowledge of technology — identifying how technologies have changed over time and exploring what people need or want
• Communication — sharing ideas with others using appropriate language for sequencing and explanation
• Thinking skills — organising information and making simple comparisons across time

Lesson structure (45 minutes)

1. 0–5 min · Starter: Timeline talk. Teacher shows a simple “then/now/soon” strip on the board and asks: “What technology did we use today?” Students quickly share one example and where it might sit on the strip.

2. 5–12 min · Direct teach: What makes a good timeline? Teacher models building a class timeline using 3–4 example cards (teacher-chosen, age-appropriate), naming the order aloud. Students echo the language: “First/then/next/future,” and point to where each card belongs.

3. 12–18 min · Group investigation: Sort the eras. In groups, students receive a set of technology picture cards (e.g., simple tools, home technologies, transport, communication). Teacher prompts: “Is this an older technology, today’s technology, or a future idea?” Students sort into past/now/future piles.

4. 18–26 min · Build: Place on the classroom timeline. Teacher distributes timeline strips and tape/markers. Students place their cards onto the timeline in order and adjust if unsure, using sequence words and discussion. Teacher circulates to check correct ordering and reasoning.

5. 26–34 min · Add explanations: “What changed?” Each group writes or dictates 2 short captions (one sentence each):

• “In the past, people used…”
• “Now/future, we use… because…” Teacher provides sentence starters for those who need support, focusing on clear, simple comparisons.

6. 34–42 min · Present: Gallery walk. Groups take turns presenting their timeline to another group (30–45 seconds each). Listeners respond with one question or “I noticed…”. Teacher listens for accurate sequencing and explanations.

7. 42–45 min · Quick reflection exit ticket. Students complete a one-minute slip: “My technology timeline shows that technology can change because ____.” Teacher collects to gauge understanding.

Resources

• Technology picture cards (group sets) showing simple past, present, and future examples
• Classroom timeline strip templates (three sections: Past / Now / Future, with simple labels)
• Sticky tape, mini whiteboards or paper, markers/colour pencils
• Sentence starter cards (e.g., “First… Then… Now… Future… because…”)
• Group roles prompts (e.g., Reader, Builder, Presenter, Timekeeper)
• Teacher example timeline strip
• Exit ticket slips and pens

Assessment

• Formative: Observe group sorting and timeline placement; note misconceptions about order (past vs now vs future)
• Formative: Check group captions for sequencing words and a meaningful “because” statement
• Summative (light): Exit ticket responses for understanding of how technology changes over time

Differentiation

• Support: Provide sentence starters, word bank (then/now/future; older/newer; faster/safer/easier), and pre-sorted sample cards for students who need extra scaffolding
• Support: Offer a “timeline chooser” tool—students point to the label before placing a card
• Challenge (advanced learners): Ask students to justify ordering with two changes (e.g., “It got smaller and faster”) or suggest a “next step” technology beyond the given cards
• EAL/SEN: Allow oral dictation for captions and presentations; use picture-backed prompts; ensure group roles include a speaking opportunity with reduced pressure

Extension (optional)

• Advanced groups design a “future version” card: add a drawing and write one prediction beginning with “Soon, people will use…” and explain why it would help.
