Labels — click a label, then click its hotspot

How to play Labelled Diagram

An interactive diagram is shown with numbered or highlighted hotspots. Click each hotspot (or the corresponding input box) and type or select the correct label. The exercise covers any subject where visual vocabulary is key — anatomy, geography, everyday objects, and more.

After labelling all hotspots, click Check to see which labels are correct. Incorrect labels are highlighted so you can fix them. Your score is based on accuracy across all labels in one submission.

Why Labelled Diagram improves your English

Visual-associative learning is one of the most efficient vocabulary acquisition strategies known to research. When you link a word to a clear visual representation — a body part, a piece of furniture, a component of a machine — the visual provides a concrete mental "hook" that makes the word dramatically easier to recall later.

Labelled Diagram also builds technical and domain-specific vocabulary that is hard to acquire through reading alone. A learner studying English for medicine, geography, or technology will find diagram exercises invaluable for mastering the specialised lexis of their field.

Memorisation tip: Before the exercise, spend 30 seconds studying the diagram as a whole — understand what the diagram represents. Then look at each hotspot area and try to predict its label from context before typing. This active prediction before confirmation is a powerful memory technique.

What you can label in this exercise

  • Human body: parts of the face, hand, digestive system, skeletal structure.
  • Geography: world maps, country borders, ocean features, topographic regions.
  • Everyday objects: rooms in a house, parts of a bicycle, sections of a classroom.
  • Science diagrams: plant cells, weather cycles, electrical circuits.
  • Language diagrams: parts of a sentence, components of a paragraph, story structure.

Tips for Labelled Diagram success

  • Use positional logic: "This is near the top/left/centre" can help you identify a part in an unfamiliar diagram.
  • Learn in clusters: Study all the vocabulary for one diagram section together before labelling.
  • Draw it yourself: After the exercise, close the screen and sketch the diagram from memory, labelling as you go.
  • Say labels aloud: Pronouncing each label as you place it adds an auditory memory layer.

Related exercises

  • Group Sort — categorise vocabulary by type, topic, or any other grouping.
  • Match Up — drag vocabulary items to their matching descriptions.
  • Flash Cards — systematic word-by-word drilling for the vocabulary you're labelling.
  • Word Magnets — arrange vocabulary tiles to build sentences about the diagram topic.

Frequently Asked Questions

How does the Labelled Diagram exercise work?
An interactive diagram is displayed with circular hotspot markers at key points. Click a label chip from the bank at the bottom of the screen, then click the hotspot you believe it belongs to. A correct placement turns the hotspot green; an incorrect one shakes red and resets so you can try again. Click Check when finished to review all answers, or Reveal All to see the full solution.
Which diagrams are available?
There are currently five diagrams: Human Face, Living Room, Weather, Bicycle, and Human Hand. Each covers a distinct vocabulary set — from facial features and body parts to room furniture and weather phenomena — giving learners broad exposure to concrete nouns across different domains.
How many labels are there per diagram?
Each diagram has eight hotspot positions, so you must place eight labels correctly to complete it. The label bank presents all eight options in a shuffled order, and used labels are greyed out once placed correctly so you can track your remaining choices.
Which CEFR levels does Labelled Diagram suit?
The vocabulary in current diagrams is primarily A1–B1. Body parts (face, hand) and everyday objects (living room, bicycle) are core A1/A2 vocabulary, while the weather and some bicycle components extend to B1. Teachers can use the exercise with beginners as an introduction and with intermediate learners as a fast-revision warm-up.
Why does visual-spatial learning help vocabulary acquisition?
When a word is learned alongside a clear visual representation, the image acts as a concrete memory anchor. This dual-coding — storing both verbal and visual information — makes words significantly easier to retrieve than words learned from text alone. Research consistently shows that picture-word associations are retained longer and recalled faster than definitions alone.
How can Labelled Diagram be used in curriculum subjects beyond English?
The labelling format maps directly onto science (human anatomy, plant structure), geography (map features, weather systems), and technology (mechanical parts). CLIL (Content and Language Integrated Learning) teachers can use these exercises to teach English vocabulary in the context of Biology, Geography, or Design & Technology lessons simultaneously.
Does the drag-and-label work on mobile and touchscreen devices?
Yes. Rather than requiring a drag gesture (which can be imprecise on small screens), the exercise uses a two-tap method: tap a label first to select it, then tap the hotspot to place it. This works reliably on any touchscreen device including phones, tablets, and interactive whiteboards.
Which other LexFizz exercises complement Labelled Diagram?
Group Sort is excellent for categorising the same vocabulary after labelling. Match Up reinforces the word-to-definition link. Flash Cards are ideal for drilling the same words as individual items before or after the diagram activity. Word Magnets lets you build sentences using the vocabulary you have just labelled.
How can teachers use Labelled Diagram in a classroom?
Project the diagram on a whiteboard and ask students to call out label placements as a whole-class activity before assigning it individually. You can also use it as a pre-reading task to introduce topic vocabulary before a reading or listening activity. The immediate visual feedback makes it well-suited to self-paced homework.
Can I add my own diagrams to the exercise?
The current version uses five built-in SVG diagrams. Custom diagram support is on the development roadmap. In the meantime, teachers who wish to create custom labelling activities can use the LexFizz open approach — the diagram data is defined in a simple JavaScript array, making it accessible for technical users to extend the exercise with their own SVG images and hotspot coordinates.
