Pangea Puzzle

Overview

Today’s Montessori-friendly inquiry lesson explores what Pangea was, when it existed in a very broad sense, why it broke apart, and how today’s continents formed. Students will investigate using a map puzzle and evidence-based discussion, then complete a one-week follow-up task set.

Learning intentions

Students will:

• Investigate and describe what Pangea was and that it existed as one large landmass long ago.
• Explain, in age-appropriate terms, that plate tectonics caused the breaking apart of Pangea.
• Link the breaking apart to the formation of today’s continents.
• Use simple scientific language to communicate findings.

Success criteria

Students can:

• Use words like Pangea, continents, landmass, plate tectonics, and “move” to describe the idea.
• Fit continents together on a puzzle/map and explain what happens when they separate.
• State that earthquakes/volcanoes and moving plates provide evidence for plate tectonics (at a simple level).
• Record ideas clearly in journals, diagrams, or a model.

Curriculum links

• Science: investigate tectonic activity including the formation of geological features at divergent, convergent and transform plate boundaries and describe the scientific evidence for the theory of plate tectonics (WALT/Students will be able to describe evidence and features in a simplified way).
• Science inquiry and communication: write and create texts to communicate ideas and findings using scientific vocabulary and digital tools as appropriate (use labels, captions, and a short explanation).

Lesson structure (60 minutes)

1. 0–8 min · Hook story/phenomenon. Teacher reads a short story: “The Great Land That Was One” (teacher-made). As the story ends, the teacher shows two pictures: (1) one ancient map shape labelled Pangea, (2) today’s world map. Students turn-and-talk: “What changed? Why would land split up?”
2. 8–18 min · Mini-lesson with visuals/analogy. Teacher uses a simple visual sequence on the board: one large “jigsaw of land” → pieces moving apart slowly → current continent positions. Teacher language prompts:

• “Pangea was one big supercontinent.”
• “It existed a very long time ago (very broadly: hundreds of millions of years).”
• “The continents move because Earth’s plates move.”
• “Plate tectonics can make land split and later form new coastlines.” Optional video is not required; use diagrams and a stretchy “plate” analogy (fabric under “continents” on a tray) to show sliding and spreading.

3. 18–33 min · Hands-on Montessori map puzzle. Students work at mixed-age stations (25 students rotate if needed; otherwise whole class shared station with pairs). Materials: laminated “Pangea fit” pieces or foam/printable continents. Task:

• Step A: Fit pieces together to form “Pangea.”
• Step B: Separate pieces slightly and “slide” them apart on the base map.
• Step C: Point to at least two places where coastlines seem to match. Teacher circulates with a checklist: vocabulary used, explanation clarity, collaboration.

4. 33–42 min · Discussion (whole class inquiry). Class circle: “What did you notice when you tried to fit the continents?” Teacher records student ideas on a chart titled: What we can see (matching shapes), What we think caused it (plates moving), What we need evidence for (earthquakes/volcanoes, patterns through time). Teacher steers toward simple evidence: “Scientists study earthquake and volcanic patterns and seafloor mapping to understand plate movement.”
5. 42–55 min · Independent work (first draft). Students choose one quick product to start now (10–13 min):

• Draw-and-label: “Pangea broke apart” with arrows, or
• “Coastline match” caption under their puzzle result, or
• Build a small model using play dough + paper continents on a tray. Teacher provides sentence stems on cards.

6. 55–60 min · Exit ticket (formative check). Each student completes a single prompt card: “Pangea was… (one sentence) and it broke apart because…” (one short sentence).

Resources

• Laminated Pangea jigsaw pieces or foam continent pieces
• Base map mat (global outline in two versions: Pangea grid + modern map)
• Sticky notes or mini arrows for “movement”
• Student journals and pencils/colour pencils
• Sentence stem cards (with word bank)
• Visual word bank: Pangea, supercontinent, continents, plates, move, break apart, long ago
• Tray materials for model (paper continents, play dough, cardboard)
• Timer for rotation/pace
• Teacher checklist/rubric sheet (see Assessment)

Assessment

• Formative observation checklist during puzzle and discussion:
• Uses target vocabulary appropriately (Pangea, continents, plates/tectonics)
• Can explain the sequence: one landmass → separation → continents today
• Participates and communicates an evidence idea (patterns/earthquakes/volcanoes at a simple level)
• Quick exit ticket (two-sentence response) to check understanding and language
• Journal review at the end of class for diagram quality and labels

Differentiation

• Dyslexia-friendly supports:
• Provide audio option for the story and instructions (teacher reads while students follow with a highlighted script)
• Visual supports: word bank, icons for “before/after,” arrows with printed labels
• Sentence stems with blanks (e.g., “Pangea was ____.” “It broke apart because ____.”)
• Reduce reading load by allowing oral explanation captured by teacher notes
• Support for diverse learners (including processing and fine-motor needs):
• Provide pre-cut puzzle sets and allow tracing of pieces onto paper
• Offer a “guided fit” template with 2–3 anchor pieces already placed
• Pair students strategically (one confident reader + one strong modeller)
• Extension for advanced learners:
• Add optional challenge card: “Find one extra reason plates can move (slab pull/ridge push/convection) using a simplified drawing.”
• Ask: “Where would earthquakes and volcanoes likely be when plates meet?” (use boundary sketch: divergent/convergent/transform)
• Optional pathways for Years 4, 5, and 6 (choose based on readiness):
• Year 4 pathway: focus on definitions (Pangea, continents) and a simple “move apart” explanation.
• Year 5 pathway: add “very long time ago” and connect to plate tectonics using a cause-and-effect diagram.
• Year 6 pathway: include “evidence” statement: patterns of earthquakes/volcanoes and how scientists map seafloor support plate tectonics.

Independent follow-up (one week)

Students complete one or more tasks (Montessori choice boards), each connected to today’s lesson:

• Journal response (2–4 short entries):
• “Before: Pangea” drawing + label
• “After: continents today” drawing + arrows
• “My evidence idea” (one paragraph or oral recorded summary)
• Research cards (print or handwritten):
• Card 1: What is a supercontinent?
• Card 2: Plate tectonics—what moves and what it causes
• Card 3: One evidence pattern (earthquakes/volcanoes) explained simply
• Label the diagram:
• Provide a worksheet with blank arrows and word bank; students label “plates” and “movement”
• Model building (small group option):
• Create a model in a tray and take a photo or draw it; include a caption explaining what part represents plates
• Vocabulary practice:
• “Match the word to the picture” for Pangea, continents, plate, tectonics, break apart

Safety and pace tips (Year 4–6 Montessori)

• Use low-mess materials first (laminated pieces) before any play dough work; wipe trays between groups.
• Keep puzzle pieces contained in trays to prevent lost items and frustration; set a clear time limit for fitting before regrouping.
• Teacher circulation every 5–7 minutes during hands-on to prevent students from moving pieces without discussion.
• For younger learners or those who tire quickly, offer a “repeat fit” option rather than expecting lengthy write-ups during class.
