# Year 6 If the World were 100 People: Teaching Plan

## A teaching plan covering statistics and probability achievement objectives

## Session 1: Introduction

- Introduction to if the world were 100 people concept
- Understanding about percentages
- Explore making data visualisations using a 100 people chart for given percentages

## Session 2: What is a census?

- Understanding what a census is, in particular, what is the census of population and dwellings in New Zealand.
- Exploring migration and birthplace statistics from the 2018 census – connecting to Whakapapa me te whanaungatanga | Culture and identity from Aotearoa New Zealand histories curriculum

## Session 3: Planning for our 100 people investigation

- Deciding the region of New Zealand to explore
- Deciding on topics of interest
- Sourcing secondary data (existing information) to use to create a “If _____ were 100 people” presentation

## Session 4: Researching examples of visualisations to use

- Exploring and interrogating data visualisations
- Deciding on visualisations to use for their “If ______ were 100 people” presentation

## Session 5: Creating data visualisations

- Creating visualisations to use in the “If ________ were 100 people” presentation
- Use a variety of data visualisations
- Making summary statements about the data
- Starting to use technology and statistical software to create their data visualisations

## Session 6: Making “ If ____ were 100 people” videos

- Students make their videos, check them, and share them with their teacher
- Students prepare their own evidence of undertaking a statistical enquiry to share with others

## Session 7: Making time series graphs

- Introduction to time series graphs

## Session 8: Gapminder trends, graphs about the world

- Exploring Gapminder trends graphs
- Reading and describing time series graphs

## Session 9: Figure.NZ graphs about New Zealand

- Exploring Figure.NZ graphs
- Attributing the charts used
- Writing descriptions of time series graphs including seasonal variation

## Session 10: Introduction to using CODAP

- Introduction to Common Online Data Analysis Platform – CODAP, a free browser-based statistical analysis tool

## Session 11: Making their own time series graphs using CODAP

- Using CODAP to explore time series datasets

## Sessions 12-13: Probability: Fair games

- Record results of a simple probability experiment
- Interpret results and decide if a game is fair

## Sessions 14-15: Scratch ‘n’ win

- Record results of a probability experiment on a tally chart
- Discuss experimental and theoretical probabilities
- Use technology to do a large number of trials

**Additional probability activities could include:**

- The rest of the I’m Spinning (NZ Maths) lessons
- Determine an experimental estimate of the probability of simple events using frequency tables.
- Determine the theoretical probability of simple events using percentages, fractions, and decimals.
- Systematically find all possible outcomes of an event using tree diagrams and organised lists.

- What’s in the bag? (NZ Maths)
- Make predictions based on data collected.
- Identify all possible outcomes of an event.
- Assign probabilities to simple events using fractions (1/2, 1/6, etc).

- Long Running (NZ Maths)
- Take samples and use them to make predictions.
- Compare theoretical and experimental probabilities.
