S Y2 Our Lost Teeth – PPDAC cycle new
A statistical enquiry aimed at Year 2 ākonga, around lost teeth. This includes follow-up suggestions for future discussions and data analysis over time.
This activity explores the following key ideas:
- contribute to formulating an investigative question that can be answered with data
- anticipate what the data might show, eg which outcomes might be more frequent than others
- discuss how the data-gathering process might affect other people
- identify who and what the data measures
- collect categorical data for more than one variable
- create data visualisations for categorical data, eg pictographs and dot plots
- describe data visualisations for categorical data, noting the frequencies of categories, eg most frequent category, least frequent category
- choose statements from class created descriptive statements that best answers the investigative question
- match statements made by others with features in simple data visualisations, and agree or disagree with the statements
