Using an interactive timeline created by the Department of Foreign Affairs and Trade, this Teacher guide provides 12 series of learning experiences that engage students in the analysis and interpretation of data about Australian trade from 1900 to the present day. Students study videos, tables, images and texts in order ...

In this sequence of two lessons, students critically assess the Census@School 2014 Questionnaire and make decisions on how they would analyse the data given the types of questions and response. They describe the life of a single participant using their survey data and use a range of statistical tools to compare their participant ...

This lesson aims to build students' algebraic reasoning and understanding of number as they explore computation on the number chart. Students explore the moves of a king chess piece and how the value of the numbers change as he moves. This builds into an algebraic exploration of equivalent values that can be found on the ...

• TLF-IDM025324

In this sequence of three lessons, students use geometric reasoning to establish relationships between angles in polygons and go on to make generalisations using algebraic expressions. Students explore and enumerate right angles in a series of rectilinear polygons and generalise their findings. They then explore the number ...

This sequence of four lessons focuses on counting large collections of objects and developing efficient counting strategies. Students explore the ambiguous nature of a 'handful' and investigate how different sized hands and different grabbing techniques will result in different quantities of macaroni. Each lesson is outlined ...

This sequence of lessons aims to develop understanding of algebra as generalised arithmetic. Students learn to express 2- and 3-digit numbers in a general form and use this to explain results of arithmetic operations involving numbers with their digits reversed. The task links the ideas of place value with algebraic reasoning. ...

This sequence of four lessons explores concepts around informal area and symmetry. Students design an 'expanded square' where approximately half the area of the original square is flipped to the outside. The lessons provide opportunities for students to devise and use methods to informally measure area, record their mathematical ...

This sequence of two lessons explores sorting numbers and place value. In the first lesson students identify the value of digits in a number and also build correct terminology to sort and describe 1-digit, 2-digit and 3-digit numbers. In the second lesson, students are challenged to use Venn diagrams to sort and describe ...

This sequence of two lessons focuses on the idea that fractions are numbers and builds students' understanding of the relative sizes of fractions. Students build their fractional sense through determining if fractions are closest to 0, 1/2 or 1. In the first lesson, students use sets of fraction cards to sort fractions ...

This lesson focuses on building students' counting skills, particularly their ability to subitise a collection (recognise the number of items in a group without the need to count them) . Students consider ways of structuring a collection so that the total can be quickly identified. They explore different arrangements for ...
