# Mathematics – Multi-age – Year B – Unit 11

This two-week unit develops student knowledge, understanding, and skills of place value, number representation, and data.

Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

Students are provided with opportunities to:

• investigate the base 10 numerical system
• quantify, organise, and represent a variety of collections
• compare numbers through different representations
• collect and organise categorical data
• interpret data to ask questions and make informed decisions
• identify simple objects on a map and describe their position in relation to another object
• create and follow instructions along a path from the beginning to the end.

### Early Stage 1

##### Representing whole numbers – MAO-WM-01, MAE-RWN-01, MA1-RWN-01, MAE-RWN-02, MA1-RWN-02
• Instantly name the number of objects within small collections
• Use the counting sequence of ones flexibly
• Recognise number patterns
• Connect counting and numerals to quantities
##### Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MA1-CSQ-01, MAE-CSQ-02
• Model additive relations and compare quantities
• Identify part-whole relationships in numbers up to 10
##### Geometric measure – MAO-WM-01, MAE-GM-01, MA1-GM-01
• Position: Describe position and movement of oneself
##### Data – MAO-WM-01, MAE-DATA-01, MA1-DATA-01, MA1-DATA-02
• Respond to questions, collect information and discuss possible outcomes of activities
• Organise objects into simple data displays and interpret the displays

### Stage 1

##### Representing whole numbers A –
• Use counting sequences of ones with two-digit numbers and beyond
• Represent numbers on a line
• Represent the structure of groups of ten in whole numbers
##### Representing whole numbers B –
• Use counting sequences of ones and tens flexibly
• Form, regroup, and rename three-digit numbers
##### Combining and separating quantities A –
• Recognise and recall number bonds up to 10
• Use flexible strategies to solve addition and subtraction problems
• Represent equality
##### Combining and separating quantities B –
• Form multiples of ten when adding and subtracting two-digit numbers
• Use knowledge of equality to solve related problems
##### Forming groups A –
• Model and use equal groups of objects to represent multiplication
##### Geometric measure A –
• Position: Follow directions to familiar locations
##### Geometric measure B –
• Position: Explore simple maps of familiar locations
##### Data B -
• Identify a question of interest and gather relevant data
• Create displays of data and interpret them
