EARLY STAGE ONE MATHS FOCUS
NUMBERS AND ALGEBRA
WHOLE NUMBERS
OUTCOME
A student:
MAe4NA: counts to 30, and orders, reads and represents numbers in the range 0 to 20
TEACHING POINT  Students may use incorrect terms since these are frequently heard in everyday language, eg ‘How much did you get?’ rather than ‘How many did you get?’ when referring to a score in a game. To represent the equality of groups, the terms ‘is the same as’ and ‘is equal to’ should be used. In Early Stage 1, the term ‘is the same as’ is emphasised as it is more appropriate for students’ level of conceptual understanding. 
LANGUAGE  Students should be able to communicate using the following language: count forwards, count backwards, number before, number after, more than, less than, zero, ones, groups of ten, tens, is the same as, coins, notes, cents, dollars. 
Expectations of Attainment
Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point  count forwards to 30 from a given number 
count backwards from a given number in the range 0 to 20  
identify the number before and after a given number  
describe the number before as ‘one less than’ and the number after as ‘one more than’ a given number  
read and use the ordinal names to at least ‘tenth’ 
Connect number names, numerals and quantities, including zero, initially up to 10 and then beyond  read numbers to at least 20, including zero, and represent these using objects (such as fingers), pictures, words and numerals 
estimate the number of objects in a group of up to 20 objects, and count to check  
use 5 as a reference in forming numbers from 6 to 10, eg ‘Six is one more than five’  
use 10 as a reference in forming numbers from 11 to 20, eg ‘Thirteen is 1 group of ten and 3 ones’ 
Subitise small collections of objects  recognise the number of objects or dots in a pattern of objects or dots instantly, 
instantly recognise (subitise) different arrangements for the same number, eg different representations of five  
Compare, order and make correspondences between collections, initially to 20, and explain reasoning  count with onetoone correspondence 
make correspondences between collections, eg ‘I have four counters, you have seven counters. So you have more counters than me’  
compare and order numbers and groups of objects  
use the term ‘is the same as’ to express equality of groups

ADDITION & SUBTRACTION
OUTCOME
A student:
MAe5NA: combines, separates and compares collections of objects, describes using everyday language, and records using informal methods
TEACHING POINT 
The word ‘difference’ has a specific meaning in this context, referring to the numeric value of the group. In everyday language, it can refer to any attribute. 
LANGUAGE

MULTIPLICATION & DIVISION
OUTCOME
A student:
MAe6NA: groups, shares and counts collections of objects, describes using everyday language, and records using informal methods
TEACHING POINT There are two forms of division:  Sharing (partitive) – How many in each group? eg ‘If 12 marbles are shared between three students, how many does each get?’ 
Grouping (quotitive) – How many groups are there? eg ‘If I have 12 marbles and each child is to get four, how many children will get marbles?’

MEASUREMENT AND GEOMETRY
LENGTH
OUTCOME
A student:
MAe9MG: describes and compares lengths and distances using everyday language
TEACHING POINT  When students are asked to compare the lengths of two objects of equal length and can consistently say that the objects are equal in length though their relative positions have been altered, they are conserving length. 
This is an important concept and develops over time.  
Once students can compare two lengths, they should then be given the opportunity to order three or more lengths. This process requires students to understand that if A is longer than B, and B is longer than C, then A is longer than C.
 
Once students can compare two lengths, they should then be given the opportunity to order three or more lengths. This process requires students to understand that if A is longer than B, and B is longer than C, then A is longer than C.  
Length and distance are distinct concepts. The term ‘length’ is generally used to describe a measure from end to end of a drawn interval, a twodimensional shape or a threedimensional object. The term ‘distance’ is generally used to describe the lineal space between two things, places or points. Activities should focus on both concepts. 
LANGUAGE  Students should be able to communicate using the following language: length, end, endtoend, sidebyside, long, longer than, longest, short, shorter than, shortest, high, higher than, highest, tall, taller than, tallest, low, lower than, lowest, the same as, near, nearer, far, further, close, closer. 
Expectations of Attainment

make and sort long and short constructions from concrete materials  
use everyday language to describe length, eg long, short, high, tall, low  
use everyday language to describe distance, eg near, far, nearer, further, closer  
use comparative language to describe length, eg longer, higher, taller than, shortest, lower than, longest, the same as  
compare lengths directly by placing objects sidebyside and aligning the ends  
compare lengths indirectly by copying a length, eg using the same strip of paper to compare lengths  
record length comparisons informally by drawing, tracing, or cutting and pasting, and by using words and numerals 
AREA
OUTCOME
A student:
MAe10MG: describes and compares areas using everyday language
TEACHING POINT  The attribute of area is the amount of surface (either flat or curved) and can be measured in square units, eg square centimetres (cm2), square metres (m2). 
In Early Stage 1, students develop an awareness of the attribute of area and some of the language used to describe area. They develop an awareness of the attribute of area through covering activities, through colouring in, and as comparisons of area are made.  
Students should be given opportunities to compare: two similar shapes of different areas where one fits inside the boundary of the other; two differentshaped areas where one can be placed on top of the other; two shapes where one shape can be cut up and pasted onto the other.  
Once students can compare two areas, they should then be given the opportunity to order three or more areas. This process requires students to understand that if A is larger than B, and B is larger than C, then A is larger than C. 
LANGUAGE  Students should be able to communicate using the following language: area, surface, closed shape, inside, outside, bigger than, smaller than, the same as. 
Superimposing – the comparison of areas by placing one area on top of another.  
Superpositioning – the comparison of areas by aligning the edges (or corners) of two areas when one is placed on top of the other. 
EXPECTATIONS OF ATTAINMENT

record area comparisons informally by drawing, tracing, or cutting and pasting, and by using numerals and words 
VOLUME & CAPACITY
OUTCOME
A student:
MAe11MG: describes and compares the capacities of containers and the volumes of objects or substances using everyday language
TEACHING POINT  The term ‘big’ is often used by students to describe a variety of attributes. Depending on the context, it could mean long, tall, heavy, etc. It is important to model with students more precise language to describe volume and capacity. 
LANGUAGE  Students should be able to communicate using the following language: capacity, container, liquid, full, empty, about halffull, volume, space, has more, has less, will hold more, will hold less, takes up more space. 
EXPECTATIONS OF ATTAINMENT

compare the volumes of two objects made from blocks or connecting cubes directly by deconstructing one object and using its parts to construct a copy of the other object  
compare the volumes of two piles of material directly by filling two identical containers, eg ‘This pile of rice has a larger volume as it takes up more space in the container’  
compare the volumes of two objects by observing the amount of space each occupies, eg a garbage truck takes up more space than a car  
use comparative language to describe volume and capacity, eg has more, has less, will hold more, will hold less, takes up more space  
record volume and capacity comparisons informally using drawings, numerals and words 
MASS
OUTCOME
A student:
MAe12MG: describes and compares the masses of objects using everyday language
TEACHING POINT  As the terms ‘weigh’ and ‘weight’ are common in everyday usage, they can be accepted in student language should they arise. Weight is a force that changes with gravity, while mass remains constant. 
Hefting’ is testing the weight of an object by lifting and balancing it. Where possible, students can compare the weights of two objects by using their bodies to balance each object, eg holding one object in each hand. 
LANGUAGE  Students should be able to communicate using the following language: mass, matter, heavy, heavier, heaviest, light, lighter, lightest, about the same as, hard to push, hard to pull. 
EXPECTATIONS OF ATTAINMENT
Use direct and indirect comparisons to decide which is heavier, and explain their reasoning using everyday language (ACMMG006)  identify the attribute of ‘mass’ as the amount of matter in an object 
use everyday language to describe objects in terms of their mass, eg heavy, light, hard to push, hard to pull

record comparisons of mass informally using drawings, numerals and words 
TIME
OUTCOME
A student:
MAe13MG: sequences events, uses everyday language to describe the durations of events, and reads hour time on clocks
TEACHING POINT  The words ‘long’ and ‘short’ can be confusing to students who have only experienced these words in terms of length measurement. Students will need experience with these words in both length and time contexts. 
LANGUAGE  Students should be able to communicate using the following language: daytime, nighttime, yesterday, today, tomorrow, before, after, next, a long time, a short time, week, days, weekdays, weekend days, time, morning, afternoon, clock, analog, digital, hands (of a clock), o’clock.

THREEDIMENSIONAL SPACE
OUTCOME
A student:
MAe14MG: manipulates, sorts and represents threedimensional objects and describes them using everyday language
TEACHING POINT  The term ‘shape’ refers to a twodimensional figure. The term ‘object’ refers to a threedimensional figure. 
Manipulation of a variety of real objects and shapes is crucial to the development of appropriate levels of imagery, language and representation.  
Local landmarks include buildings, rivers, rock formations and bridges, as well as Aboriginal landmarks. Aboriginal landmarks may include contemporary landmarks and local points of interest. Local Aboriginal communities and education consultants can provide examples 
LANGUAGE  Students should be able to communicate using the following language: object, shape, size, curved, flat, pointy, round, roll, slide, stack.

TWODIMENSIONAL SPACE
OUTCOME
A student:
MAe15MG: manipulates, sorts and describes representations of twodimensional shapes, including circles, triangles, squares and rectangles, using everyday language
TEACHING POINT  It is important that students experience shapes that are represented in a variety of ways, eg ‘tall skinny’ triangles, ‘short fat’ triangles, rightangled triangles presented in different orientations and of different sizes, and shapes that are represented using a variety of materials, eg paint, images on the computer, string. Manipulation of a variety of real objects and shapes is crucial to the development of appropriate levels of language and representation. 
In Early Stage 1, it is important that teachers present students with both regular and irregular shapes (regular shapes have all sides and all angles equal). However, students are not expected to use the terms ‘regular’ and ‘irregular’ themselves.  
Students should be given time to explore materials in order to represent shapes by tearing, painting, drawing, writing, or cutting and pasting. 
LANGUAGE  Students should be able to communicate using the following language: shape, circle, triangle, square, rectangle, features, side, straight line, curved line, open line, closed shape.

POSITION
OUTCOME
A student:
MAe16MG: describes position and gives and follows simple directions using everyday language
TEACHING POINT  There are two main ideas for students in Early Stage 1: following an instruction to position an object or themselves, and describing the relative position of an object or themselves. Some students may be able to describe the position of an object in relation to themselves, but not in relation to another object. 
In Early Stage 1, students use the terms ‘left’ and ‘right’ to describe position in relation to themselves. They are not expected to use the terms ‘left’ and ‘right’ to describe the position of an object from the perspective of a person facing in the opposite direction until Stage 1. 
LANGUAGE  Students should be able to communicate using the following language: position, between, next to, behind, inside, outside, left, right, directions. 
EXPECTATIONS OF ATTAINMENT
Describe position and movement  give and follow simple directions to position an object or themselves, eg ‘Put the blue teddy in the circle’
