The Connections 2015's activities sequence:

 Activity synopsis Statistical ideas and concepts No. of lessons The first cycle: Several contexts (favorite movie, usage of technology, favorite snack etc.) Activity 1: Introduction - modelling and data analysis of the class (n=25 cases) 4 Ask a question, plan, collect data from the whole class, model a conjecture about the target population, analyze and organize data, present investigations (hands-on) The investigative cycle, Uncovering children’s initial concepts of reasoning with data, modelling and IIR Activity 2: Data analysis of the class (n=25 cases) 2 Investigate a data sample from activity 1 (25 cases 2 variables, TinkerPlotsTM), present investigations How to ask a statistical question, The investigative cycle, initial reasoning with data, modelling and IIR Activity 3: The favorite snack activity - modelling and data analysis of the class (n=25 cases) 2 Investigate data sample (25 cases, 3 variables), model a conjecture about the target population (TinkerPlotsTM), present investigations Initial reasoning with data, distribution, comparing groups, modelling and IIR Activity 4: The favorite snack activity - modelling and data analysis of the grade (n=73 cases) 2 Investigate the same question (activity 3) on a larger sample (73 cases, 3 variables, TinkerPlotsTM), model a conjecture about the target population (hands-on), present investigations Initial reasoning with data, distribution, comparing groups, modelling and IIR The second cycle: The amazing race activities Activity 5: Data collecting of the entire fifth grade 2 Introduction to the activity context, the electronic questionnaire, measurements errors, data collection How to answer a statistical question, Awareness to the importance of precise data Activity 6: Modelling and data analysis (n=10 cases) 3 Model a conjecture about the target population (hands-on), investigate data sample (10 cases, 18 variables, TinkerPlotsTM), refine model, present investigations Correlations, Noise in the data as a result of measurement errors, The meaning of the median, reasoning with modelling Activity 7: Modelling and data analysis of the class (n=24 cases) 2 Investigate the same question (activity 6) on a larger sample (24 cases, 18 variables, TinkerPlotsTM), refine the previous model (hands-on), present investigations Growing samples, reasoning with data, distribution, comparing groups, modelling and IIR Activity 8: Modelling and data analysis of the grade (n=62 cases) 2 Investigate the same question (activity 7) on a larger sample (62 cases, 18 variables, TinkerPlotsTM), refine the previous model (hands-on) Growing samples, reasoning with data, distribution, comparing groups, modelling and IIR Activity 9: Modelling of the target population 4 Model the conjecture about the target population (TinkerPlotsTM Sampler) Reasoning with data, modelling and IIR Activity 10: Summarizing 5 Prepare a presentation of the investigation and the target population final model, present investigations and models in a student-parents event, write a final report with parents Reasoning with data, modelling and IIR Total number of 45-minute lessons: 28
