Qualitative Interpretation of Graphs

Category Details
Module Qualitative interpretation of Graphs
Teaching Hours 3 X 40 minutes
Grade Level/Age Range Grades 5-6 (10-12 years old)
Brief Description Students use graphs to model real-life scenarios, interpret intuitively how changing a graph modifies the quantities involved in a real-life scenario and represent linear relations.
Design Principles
Inquiry
Situatedness
Digital tools
Embodiment
  • Meaningful: Build on students’ intuitive knowledge and daily life experiences with real-life scenarios
  • Embodiment: Perceptual-motor (action-perception) experiences with noticing the impact of changing the values of sliders on graphs, grounding the understanding of the relation between the involved quantities (gradient and y-intercept) with concrete actions
  • Inquiry based learning: explore qualitative interpretations of graphs
  • Digital: tablet devices equipped with appropriate apps
  • Didactical phenomenology / situatedness: modeling of real-life scenarios through changing the parameters of linear relations

Learning Goals
- Model real-life scenarios using graphs
- Explain how changing the y-intercept of a graph and its steepness modifies the quantitative relations of a real-life scenario
- Pose problems based on graphs that represent linear relations
