The Array Game - Calculate

The purpose of this game is for students to construct arrays and to describe them in words and numbers.

Even and Odd Orcharding - Calculate

What makes even numbers special? What makes odd numbers… well… odd? Help these farmers plant their fruit trees in rows and patterns, and see what happens when we add, subtract and multiply different combinations of these numbers together! Use this low threshold, high ceiling task to explore the properties of even and odd numbers.

Multiplication: reSolve Market

This sequence of 8 tasks builds the mathematical ideas idea of multiplication as ‘how many groups’ and ‘how much in each group’. Students learn that ‘how many groups’ and ‘how much in each group’ is represented in the array, where rows and columns represent factors that can be multiplied to find the product.â€¯Through the ...

Making and using equal groups: K–2 Year A – Unit 13

This sample unit introduces students to making and using equal groups.

Multiplication and division: Year 3 – planning tool

This planning resource for Year 3 is for the topic of Multiplication and division. Students further develop multiplication and division concepts. They multiply and divide one- and two-digit numbers. Students represent problems using number sentences, diagrams and arrays, and use a variety of calculation strategies.

How many clumps?

This series of lessons develops students' skills, knowledge and processes of multiplicative thinking, incoporating a First Nations perspective.

Visual to text coding: Lesson 6

This is the sixth in a series of lessons to transition from visual coding to text-based coding with a General Purpose Programming language. This lesson may take two to three 45-minute periods. It builds on the previous introduction to arrays (also called lists) and brings in the length property.

Visual to text coding: Lesson 9

This is the ninth in a series of lessons to transition from visual coding to text-based coding with a General Purpose Programming language. This lesson may take two to three 45-minute periods. It explores creating powerful programs for managing and analysing data, by combining the previous skills of using loops and working ...

What is the area?

Use this diagnostic task to assess what students know about area and using the area formula.

Tiling problem

Use this diagnostic task to assess if students use an array structure when working out how many tiles fit in a rectangle.

Multiplying two-digit numbers using the area model - Calculate

This resources describes some games and activities that can be used to help students to learn strategies to solve multi-digit multiplication problems, including using the area model.

Work sample Year 3 Mathematics: Ways to make 18

This work sample demonstrates evidence of student learning in relation to aspects of the achievement standards for Year 3 Mathematics. The primary purpose for the work sample is to demonstrate the standard, so the focus is on what is evident in the sample not how it was created. The sample is an authentic representation ...

Multiplication and division: Year 2 – planning tool

This planning resource for Year 2 is for the topic of Multiplication and division. Students begin to explore multiplication and realise that it can be represented in many ways.

Visual to text coding: Lesson 5

This is the fifth in a series of lessons to transition from visual coding to text-based coding with a general purpose programming language. This lesson may take two to three 45-minute periods. It introduces how to create and use arrays (also called lists).

In this lesson students revise and extend fluency of recall of the 4× facts. Students develop proficiently in multiplying and dividing by four, understanding the patterns in multiples of four, and applying strategies for mental multiplication with an emphasis on visual and numerical pattern recognition.

reSolve: Multiplication: Trays of Arrays

This sequence of 7 tasks uses the array to explore the distributive and associative properties of multiplication. Students use different strategies to calculate the number of items in arrays, and use mathematical reasoning to explain which strategies are the most useful. Students learn to use the distributive property to ...

What needs to be measured determines the unit of measure: K–2 Year A – Unit 14

This two-week sample unit develops student knowledge, understanding and skills of measurement.

Years 9–10: Data science skills

This unit introduces data science as a process, focusing on specific skills used in data science. These include the acquisition of data from surveys, sensors or online repositories; storage and analysis of that data; and its visualisation, including with interactivity. When acquiring and analysing data, students can apply ...

The Mathscots: Visiting the Dog Groomer - Groomer Give Aways

In this animated video, Prime and Poly are offered free shampoo samples when they visit the dog groomer. Can Abacus the cat help to work out how to share the samples equally when more dogs arrive? The mathematical focus is on understanding that multiplication and division problems can be modelled using equal groups, sets ...

reSolve: Authentic Problems: Bunches of Balloons

This sequence of three lessons introduces division and multiplication through the context of decorating a room with clusters of balloons.
