This depends on how and with what materials you want to work out the categorising and in what form. This can range from a single pre-prepared worksheet to materials you collect with the children in the forest.
1. Cards or pictures
Word cards (e.g. nouns, verbs, emotions, professions)
Pictures or photos (animals, objects, nature, people, situations)
Theme-specific sets (e.g. autumn, traffic, farm)
2. Physical objects (if available)
Small objects from classroom or school, park and forest etc.
Toys or materials from corners (cars, plastic animals, blocks)
3. Worksheets/sort sheets
Blank sort sheets with boxes or circles
Worksheets with space to name categories
Venn diagrams or matrices (for slightly older or stronger pupils)
4. Thematic materials (subject-specific)
Language: words by theme or word type
Maths: sums, numbers, units of measurement
World orientation: nature images, weather symbols, maps
Social education: pictures of behaviour, emotions or situations
5. Digital materials (optional)
Digi board or tablet with drag-and-drop categorization tasks
Online tools such as educational apps or digital learning environments
Key tip:
Choose materials that contain enough variety and doubt, so that students must think about why something does or does not fit into a category – this triggers critical thinking.
