This information is found in the wrap around pages of the teachers module. It details the Curriculum Framework Outcomes addressed in the module.

Outcomes 1 & 2 should be an inherent part of all mathematics lessons.

1. Show a disposition to use mathematics to assist with understanding new situations, solving problems and making decisions, showing initiative, flexibility and persistence when working mathematically and a positive attitude to their own continued involvement in learning and doing mathematics.

2. Appreciate that mathematics has its origins in many cultures, and its forms reflect specific social and historical contexts, and understand its significance in explaining and influencing aspects of our lives.

Outcomes 3, 4 & 5 "Working Mathematically" are an integral part in the design of every module. These outcomes determined the three stage learning process developed in each module.

3. Call on a repertoire of general problem-solving techniques, appropriate technology and personal and collaborative management strategies when working mathematically.

4. Choose mathematical ideas and tools to fit the constraints in a practical situation, interpret and make sense of the results within the context and evaluate the appropriateness of the methods used.

5. Investigate, generalise and reason about patterns in number, space and data, explaining and justifying conclusions reached.

Outcomes 6 from "Number" and 18 from "Algebra" are specific to this module.

6. Read, write and understand the meaning, order and relative magnitudes of numbers, moving flexibly between equivalent forms.

18. Read, write and understand the meaning of symbolic expressions, moving flexibly between equivalent expressions.

This information is found in the wrap around pages of the teachers module. It details the major student outcomes that should have been developed during the module.

### Major Student Outcomes

During this module students should have been developing the following outcomes:

Working mathematically outcomes at levels 4, 5 and 6 are interwoven with the structure of these modules.

The outcomes below are dealt with specifically in this module.

Outcomes from different strands are integrated into this module.

### Number

N 6.1 Reads, writes, says and understands the meaning, order and relative magnitude of positive and negative rational numbers and numbers expressed with integer powers.

N 7.1 Reads, writes and moves freely between various forms of real numbers including using powers and roots, recurring decimals and decimal approximations for irrational roots.

N 6.3 Calculates with positive and negative numbers, decimals, fractions and integer powers, using mostly mental strategies including for frequently used fractions and percentages of amounts.

### Algebra

A 5.1 Uses a letter to represent a variable quantity in an oral or written expression involving one or two operations.

A 6.1 Uses and interprets basic algebraic conventions for representing situations involving a variable quantity and explains why two linear expressions are equivalent.

{slider=Details}

This information is found in the wrap around pages of the teachers module. It gives details about the module.

### Module Length:

Approximately 3 weeks (12 hours). This may vary upward according to the ability and prior understandings of the students.

### Outcomes Levels:

Includes outcomes from levels 5, 6 & 7.

### Stage/Number:

Each Integrated Maths Module has been assigned a stage and number. The stage is designed to help teachers in their sequencing of modules. The number is for identification of each module.

This module is F01, that is stage F module 1.

The content of this module is:

Index Laws
Scientific notation

### Language development:

The following terms (or derivations of them) are an essential part of this module:

power
base
index
indices
scientific notation

These terms are in bold whenever they appear in this text.

{slider=Samples}

The structure of all modules is to present materials in three stages:

### Exploration - Formalisation - Application

The files available here for downloading are a Sample Activity from the Exploration Stage of this module and a Sample Application from the Application stage of this module.

These files are available as pdf files. To view and print these files you will need a program like Adobe Acrobat Reader which is available free here.

Sample Application

This information is found in the wrap around pages of the teachers module produced for Western Australian schools. It details the links to the old Unit Curriculum objectives for schools trying to adapt programmes etc.

Unit Curriculum Objectives covered are:

From Mathematical Development 3.4

• N 3.4 Express numbers using scientific notation.

From Mathematical Development 4.4

• N 4.2 Investigate powers of integers.
• N 4.4 Develop an understanding of operations using numbers expressed in scientific notation.
• N 4.7 Develop further understanding of square and cube roots, using a calculator.
• N 4.10 Investigate number situations and patterns which lead to generalisations, including:
• (i) the equalities
• am.an = am + n
• (am) n = am x n
• am / an = am Ã¢â‚¬â€œ n
