Selection of outcomes and content

Tier 1
DS1.1 Gathers and organises data, displays data using column and picture graphs, and interprets the results

WMS1.2 Uses objects, diagrams, imagery and technology to explore mathematical problems

• gathering data and keeping track of what has been counted by using concrete materials, tally marks, words or symbols
• using objects or pictures as symbols to represent data, using one-to-one correspondence eg using a block to represent each car
• displaying data using column graphs and picture graphs
• interpreting information presented in picture graphs or column graphs

• display data to communicate information gathered in other key learning areas eg data gathered in a unit on Mini Beasts (Communicating, Applying Strategies, Reflecting)
• use simple graphics software to create picture graphs (Applying Strategies)
• interpret data displayed in simple picture graphs and column graphs found in books and made by other students (Applying Strategies, Reflecting)

Tier 2
DS2.1 Gathers and organises data, displays data using tables and graphs, and interprets the results

WMS2.2 Selects and uses appropriate mental or written strategies, or technology, to solve problems

• creating a simple table to organise data
• constructing vertical and horizontal column graphs and picture graphs on grid paper using one-to-one correspondence
• marking equal spaces on axes, labelling axes and naming the display
• interpreting information presented in column graphs and picture graphs
• representing the same data in more than one way eg tables, column graphs, picture graphs

• create a table to organise collected data, using a computer program eg spreadsheets (Applying Strategies)
• compare tables and graphs constructed from the same data to determine which is the most appropriate method of display (Reasoning)

Tier 3
DS3.1 Displays and interprets data in graphs with scales of many-to-one correspondence

WMS3.2 Selects and applies appropriate problem-solving strategies, including technological applications, in undertaking investigations

• determining a suitable scale for data and recording the scale in a key eg ? = 10 people
• drawing picture or column graphs using a key or scale
• interpreting a given picture or column graph using the key or scale
• naming and labelling the horizontal and vertical axes

• collect, represent and evaluate a set of data as part of an investigation, including data collected using the Internet (Applying Strategies)
• determine what type of graph is the best one to display a set of data (Reflecting)
