Comments from teachers involved in consultation process
“Maths Milestones 3 was extremely user-friendly and easy to follow. “Very useful for newly - qualified teachers – clearly defined and shows a clear progression within Level 3.” “Commercial schemes usually jump from one Level to the next Level but pupils need the small steps inherent in the progression within Maths Milestones 3.” “The intervention strategies identified to use with pupils are clear, appropriate and concise.” “I found it useful as a baseline assessment of pupils for identification of their knowledge and skills to date. Using Maths Milestones 3 highlighted the areas that a pupil needed more reinforcement with or the skills that needed more explanation. It gave me confidence that I was helping to close the gap in the pupil’s learning.” “I thought that some pupils were working at Level 3 but the Assessment Checks indicated that they had gaps in their understanding and I realised that these pupils would need more time to build a sound knowledge of Level 3.” “Maths Milestones 3 would be very useful for KS 1 teachers to use alongside the assessment of pupils they think may be Level 3.” “Introducing division alongside multiplication may initially appear a challenge since most schemes usually leave a gap before introducing division. But I understand that pupils working with multiplication and division together from the beginning highlights the links and builds strength in both understanding and problem solving.” “Flexibility in thinking is encouraged within multiplication and division by introducing the tables in a very structured order and linking new facts to tables pupils already know.”

INTRODUCTION
READINESS CHECK
Numeracy is the development and application of mathematics across the curriculum and in real life situations……Activities should be balanced between tasks which develop knowledge, skills and understanding, and those which develop the ability to apply mathematical learning and solve problems (The Northern Ireland Curriculum Primary, CCEA, 2007). The Numeracy Strategy identifies approaches that contribute towards improvements in teaching and learning of numeracy. During our work with schools teachers request additional guidance and support for those pupils, regardless of age, who are struggling mathematically. Many of these pupils require a little more time than their peers to grasp mathematical ideas, as well as a structured progression in small achievable steps. Two teacher guidance documents have been developed to support Number from level 1 – level 3. Maths Milestones 1 and 21 was developed in 2005 and was shared with teachers through in-service training in October 2006. Maths Milestones 1 and 2 supported the development of mental approaches to calculation within 100 and Maths Milestones 3 has been developed for pupils who have successfully developed the skills for Assessment Check 10 within Maths Milestones 1 and 2 (i.e. those pupils who have a firm grasp of skills within level 2 Number). If pupils are still struggling with the following mathematical concepts and skills they will need to work with the practical activities outlined in the original Maths Milestones 1 and 2 document.
Demonstrate 1:1 correspondence within 5 Partition sets within 5 confidently Demonstrate conservation of number within 10 Appreciate the inverse relationship between addition and subtraction Apply knowledge of addition and subtraction within 10 across a range of contexts Know, recognise and order numbers to 50, then 100 Understand composition of 2-digit numbers to 20, then 99 Partition numbers within 50 into tens and ones Understand our number system to 100 by describing the position of any number on
the 1-100 square Mentally add and subtract two 2-digit numbers within 50, then 100
If pupils have successfully gained these concept and skills they should be ready to work within level 3 Number using this Maths Milestones 3 document.

PURPOSE
KEY PRINCIPLES
Mental approaches
Mathematical language
Pupil involvement
The purpose of these materials is to provide teachers with a series of Assessment Checks to enable them to identify pupil strengths, alongside the appropriate activities to develop the pupil’s understanding of Number. These activities are designed to support the development of further mathematical skills and concepts (i.e. more maths milestones) rather than representing a series of tasks to be completed. The focus is on encouraging pupils to be confident in Level 3 aspects of Number, which should provide a secure foundation for work in other strands of mathematics as well as future number development.
Pupils should be encouraged to consider mental methods as a first resort in any calculation (Northern Ireland Strategy for Numeracy, Teaching and Learning file2, 2000). Anghileri (2000) also notes that “All pupils are expected ultimately to use efficient written methods for calculating but the only way such methods can be meaningful is if they are developed progressively to support and extend mental strategies”. Borthwick and Harcourt-Heath’s (2007) research looked at the range of calculation methods that pupils use when working within the four operations and revealed that pupils often find it difficult to choose the most efficient and effective strategy when faced with a written test situation. Their research showed that when pupils use a calculation strategy which is based on mental methods they usually reach the correct solution. This supports the emphasis placed within Maths Milestones 3 on pupils’ personal methods of recording prior to the introduction of more formal written recording. Use of language within these mathematical activities is fundamental to progression within pupils’ thinking. Modelling the use of specific mathematical terminology over a period of time is necessary before pupils can begin to use this language to explain their understanding. Opportunities for pupils to use language to express their thinking provide valuable assessment tools. Use of open and closed questioning techniques by both pupils and teachers encourages a rich language environment that challenges pupils’ thinking (Appendix 4.1) Integrating thinking skills into mathematics means designing learning so that pupils will think more skilfully than they would otherwise do and as a result deepen their understanding across a range of contexts. Rich collaborative tasks allow learners to make decisions; involve learners in testing, proving, explaining, reflecting and interpreting; promote discussion and communication; encourage originality and invention; encourage ‘what if?’ and ‘what if not?’ questions; are enjoyable and contain the opportunity for surprise (Improving learning in mathematics: challenges and strategies, 2005, DFES). 2 Teaching and Learning file (T&L file) published by the Inter-Board Numeracy Group, 2001

HOW TO USE
Structure
The teaching approaches encouraged within these materials support the three core elements of Every School a Good School – a strategy for raising achievement in literacy and numeracy (2008) Wave One: Quality whole class teaching Wave Two: Quality teaching plus additional support for identified pupils Wave Three: Quality teaching plus personalised support to meet the specific needs of
individual pupils Maths Milestones 3 provides support for pupils working towards Level 3 in Number. The materials are flexible and may be used to support whole class (Wave One), target groups (Wave Two) or individuals (Wave Three) within the numeracy lesson alongside appropriate classroom experiences. For example, within Wave Two support, an appropriate quality learning activity could be identified for the target group for that lesson and the role of the teacher is to actively teach / facilitate quality group interaction whilst the rest of the pupils work independently on appropriate activities to further develop their learning. Teacher guidance material is provided on Language (Appendix 4.1) and a Suggested Order for Teaching the Multiplication Tables (Appendix 4.2) as well as a Resources list and some Support Materials within Appendices 4.4 and 4.6 respectively. Appendix 4.3 provides a Pupil Record format to monitor skills progression as pupils work through the preparation activities and Assessment Checks and informs the next learning and teaching cycle. Maths Milestones 3 is structured as a series of Preparation Activities that develop a range of skills which are subsequently monitored through an appropriate Assessment Check. Preparation activities become progressively more challenging within and between each Assessment Check. This is not intended to restrict flexibility in use, but does indicate the structured progression inherent in mathematical conceptual development.

Assessment
Maths Milestones 3 can be used to support Assessment for Learning. Elements within the Assessment Checks and the Preparation Activities can be used as targets for individual pupils or for groups of pupils. Targets and Learning Intentions can be shared with pupils so they can monitor their progress. Effective feedback tells learners where they have been successful, where they should focus their next improvement and precisely how to go about making that improvement happen. The oral introduction aspect of lessons could be linked to some of the preparation activities. Most of the tasks could form the basis of the main practical element of the lesson for a target group of pupils. It is anticipated that pupils would experience the whole range of preparation activities before moving on to the next Assessment Check. If pupils are still struggling with a particular preparation activity, teachers may need to review related activities in previous Assessment Checks. Some of the maths milestones may need to be more formally assessed as a pupil works through the Assessment Checks e.g. quick recall activities. An initial assessment of each pupil within a target group could involve identifying which Assessment Check and its Preparation Activities best describes the pupil’s current level of understanding. For example, a pupil may be capable of achieving most of the statements within Assessment Check 13 and some of those within Assessment Check 14. This pupil would progress most by completing the full range of Preparation Activities supporting Assessment Check 13 before moving on to those related to Assessment Check 14. Assessment forces us to recognise that each learner is an individual with different learning needs, and to adapt the pace and content of teaching accordingly (Improving learning in mathematics: a professional development guide, 2005, DFES). The class teacher should liaise with the numeracy coordinator, SENCO and external educational partners to ensure an integrated approach within all of the numeracy provision for pupils.

Throughout the following preparation activities
pupils should always have opportunities to use
appropriate language in collaborative working
situations. They should be encouraged to
engage in effective questioning and to use
practical materials as appropriate.
How many cubes do you think “Dienes
man” is made from?
More importantly…How could we begin to count the cubes?

APPENDIX 4.1: LANGUAGE
Frequently pupils struggle with the language associated with problem solving and investigation activities. This needs to be considered carefully along with their knowledge of the appropriate mathematical language for pupils to be confident using the four operations. For example, there are many ways of asking simple addition and subtraction problems and pupils need experience of both responding and asking questions within a broad range of scenarios:
Joe had 13 marbles. Then Tom gave him 5 more marbles. How many marbles does Joe have now? Joe had 13 marbles. Then Tom gave him some more marbles. Now Joe has 18 marbles. How many marbles did Tom give him?
Joe has 18 marbles. Tom has 5 marbles less than Joe. How many marbles does Tom have? Joe has 18 marbles. He has 5 more marbles than Tom. How many marbles does Tom have?

How am I going to do it? Is it similar to anything
I’ve done before? Is it one of those?
Do I understand it so
far? Do I need to ask a
question? Am I on the right track? Is there a better way?
How did I do it? What method / strategy
worked? What did I learn? Did my plan work out? Can I learn from my
mistakes? Can I do better next

RACE TO PLACE
Resources: 0 -9 dice and a copy of the grid (left) Number of players: 1, 2 or small group work Aim: To fill each of the 8 ‘rungs’ of the ladder (left) with three-digit numbers. The completed ladder must have the largest number at the top of the ladder and the smallest number at the bottom, with the remaining numbers arranged in ascending order. Instructions: Each player has their own ladder. Player 1 throws the 0-9 dice three times and records the three numbers thrown, e.g. 5, 7 and 1. Player 1 generates a three-digit number using these three numbers. Finally player 1 has to decide on which rung of the ladder to place the number. If playing against a partner, then player 2 takes their turn now. Winner: The winner is the first player to complete their ladder with all numbers in order. Tip: If a small number is generated first – don’t automatically place it on the bottom rung (unless you’re lucky enough to throw 111).

Find two consecutive numbers with a product of 240
Zero or Hero?
Choose any three digit number (e.g. 347). Can you subtract three numbers to produce zero?
(e.g. subtract 300, subtract 40 and subtract 7)
On Target
The game works as with ‘Zero or Hero’ except that pupils begin at zero and add three numbers to get to
their target three digit number (e.g. 742)
What needs to be added/subtracted to change
823 to 898 & 370 to 971 ?
Put five hundred and two into your calculator. Is
the zero important? Why?

LOOP CARDS
Loop Cards can be used to help pupils consolidate multiplication facts. On each Loop Card there is a multiplication fact to be solved. The answer to the multiplication fact will be found in the circle at the top left of one of the other Loop Cards.
What to Do
In pairs (or individually) choose a card to start the loop.
Take it in turns to solve the problem on the card.
Find the card which has the answer and place it clockwise.
Continue until you have used all the cards to make a complete loop.
Extension
When the pupils are familiar with Loop Cards they could design a set of their own Loop Cards for their friends to use.

BE THE TEACHER
A useful activity for pupils is to ask them to consider a set of number facts and to decide if they are correct or incorrect.
These facts could be presented on flashcards, written on the board or called out orally.
e.g. Double 9 = 19 6 x 4 = 24 17 is 1 more than 3 x 5 Double 20 plus 5 = 45
Pupils could also use flashcards to give their responses.
Examples
Alternatively pupils could indicate whether the number fact is correct or not by indicating “Thumbs Up” or “Thumbs Down”.

TABLEMASTER This is a game for 2 or 3 players. You will need: one 10-sided dice and one six-sided dice a set of counters for each player a playing board RULES (up to 6 x 10 game) A The first player throws both dice. The two numbers shown
are multiplied together, and if the answer is shown on the board, the player covers the number with one of his counters. If a zero is thrown, this can be scored as 0 or 10.
B The next player throws both dice, multiplies the numbers and if the result is on the board and not already covered, he places a counter on the number.
C If any player cannot place a counter on the board, play moves to the next player.
D Play continues until one player forms an unbroken straight line of THREE counters, vertically, horizontally or diagonally.
VARIATIONS Change the numbers on the playing board
Use a 1-6 dice to simplify the game or a blank dice approximately
numbered for the level at which the pupils are working
