# Year 5 Making Decisions with Data

Australian curriculum number (ACMSP118, ACMSP119, ACMSP120)

## Summary of learning goals

It is important for students to learn how to collect, present and read data effectively, so that they might make reasoned judgements and decisions. This sequence of lessons takes students to a point where they can collect and analyse data to answer their own inquiry questions. They may use technology to enhance the presentation and interpretation of the data they collect. Using data that is personally or socially relevant for students enhances their engagement with the activities.

## Rationale for this sequence

We are constantly surrounded by data and statistics. The ultimate purpose of this sequence is to help students to be able to use data effectively to make informed and intelligent statements based on evidence.

This sequence is organised so that students determine the required elements of a good graph through a structured and supported process, then collect and represent data from a class-based activity, and finally develop their own personal inquiry to answer a unique and individual question. In this way, the sequence itself builds knowledge and understanding of good data representation so that students are empowered to support their own research with effective graphs.

This sequence will also provide an opportunity for explicit instruction in the use of commercial spreadsheet software to construct tables and graphs. Teachers will be able to model effective use of tables to represent data and how to produce graphs complete with titles, labels and legends.

### reSolve Mathematics is Purposeful

Problem solving – Students are given the opportunity to define and explore issues that are relevant to them and their personal context. They design an inquiry question and then collect data that helps them draw conclusions about the issue that they are investigating. They find solutions to problems by engaging directly with the data and making informed statements based on evidence.

Reasoning – One of the primary functions of collecting data is to use it to answer questions or make statements of fact. Students are provided with many opportunities throughout these lessons to participate in the process of making observations and drawing conclusions based on the information they collect.

### reSolve Tasks are Challenging Yet Accessible

Accessibility in this sequence arises from the use of data that students collect for themselves that relates to an issue or topic of their own choosing. The careful sequence of lessons leads students from deciding what the important elements of a good graph are to the point where they are able to investigate their own questions, find evidence to support an idea and present their findings effectively.

### reSolve Classrooms Have a Knowledge Building Culture

Students will work collaboratively through the activities in these lessons as they collect and present data. They will be active in their engagement with tasks and have the opportunity to take risks as they explore issues. The summative “product” of each student will potentially be quite unique and reflect their growth and development as a learner.
