Title: Bridging Mathematics and Computer Science with Haskell
Venue: Computing at School Conference, Birmingham, UK

Workshop session summary: The statutory entitlements for mathematics and computer science require learners to be able to move fluently between representations of mathematical ideas and to master computational thinking. At university level conceptual mathematics unifies the study of algebra, geometry and logic. We have developed a set of (6) exercises that apply conceptual mathematics to meet these new entitlements.

In this session we will show how to apply this approach to Caleb Gattegno's early algebra. Gattegno was a pure mathematician and educationist who was founding secretary of the Association of Teachers of Mathematics (ATM). He uses Cuisenaire resources to teach all four arithmetic operations and fractions as operators in Year 1 as required in the new curriculum. His is the only proven way to do this. In Gattegno's concept graph algebra is introduced before arithmetic through the study of constructions made with colour coded rods. We have been exploring the use of Haskell as a language to model these elements and operations across the transition from primary to secondary school. We have found that it provides a useful bridge between the statutory requirements for mathematics and computer science as well as an invaluable vehicle for teacher professional development.

Speaker biography: Ian Benson is acting CEO of Sociality Mathematics CIC, a community interest company that supports a network of schools following the Cuisenaire-Gattegno approach to mathematics. He is a member of the General Council of the ATM. Ian has a PhD in Computer Science (Cantab), a Masters in Symbolic Computation (Stanford) and a Masters degree (Cantab) in Mathematics. This workshop describes the results of a pilot project with Year 6 and Year 7 mathematics and computer science students.


Seminar June 2

Gattegno’s cryptomorphisms: Modeling algebraic understanding in the early years
Room 102, Jordan Building, Stanford University

Caleb Gattegno was a pure mathematician and educationalist. A sometime associate of Jean Piaget and Jean Dieudonne, Gattegno pioneered a radical reconceptualization of pre-university mathematics, including advocating the study of algebra before arithmetic. Gattegno approached teaching the integer and rational number systems through student investigations using sets of ideograms of color coded cuboids (“Cuisenaire rods”) in a variety of configurations together with the equivalence relations between them. He wrote, "All mathematical discoveries of importance can be traced to a dynamic alteration within our mind of existing organized images, or ideas."(1) He elaborated a theory of learning to account for this process. A central idea was that, in learning to listen and speak, or to see and move, a baby has already developed the capacity to reason algebraically. Educationists have recently rediscovered the merits of "early algebraization."(2,3) Similarly his learning model forshadows "dual process" psychological theories of higher cognition.(4) To Gattegno, all mathematical reasoning was grounded in mental imagery that required a conscious “awareness” of algebraic structure for its manipulation. His proposal for the new (Cui) curriculum challenged the learner with a series of progressively more complex “rod worlds.” Elements and actions in the rod world are mirrored in virtual actions on imagery suggested by these actions. Color codes and notation are used to give names to these elements and actions. Learners are encouraged from Year 1 (aged 5) to read and write expressions and equations in simple formal languages. They learn to move fluently between these representations of mathematical ideas so that the elements and operations or actions of one structure can be substituted for the elements and operations or actions of the other: a “cryptomorphism.” In this seminar we will explore exercises drawn from Gattegno's text-books, and illustrate these activities with examples of students’ work.

Title: Graphs, Codes, Number Systems and Gattegno
Who: Ian Benson (ATM General Council), Anne Haworth (ATM Chair)

The statutory entitlements for mathematics and computer science require learners to be able to move fluently between representations of mathematical ideas and to master computational thinking. At university level conceptual mathematics unifies the study of algebra, geometry and logic. We have developed a set of exercises that apply conceptual mathematics to meet these new entitlements. In this session we will show how to apply this approach to Gattegno's early algebra. Gattegno uses Cuisenaire resources to teach all four arithmetic operations and fractions as operators in Year 1. We compare our approach to other ways of meeting the 2014 curriculum aims.

City Heights e-Act Academy
Workshop Session: Monday 4 January
Title: Getting Started with Early Algebra
Who: Ian Benson, Suzanne Spencer

The Cuisenaire resources are increasingly popular in primary schools as a means of introducing learners to the relationship between numbers, both whole numbers and fractions as operators. Caleb Gattegno popularised Cuisenaire's invention and wrote a series of influential textbooks that taught algebra before arithmetic, using colour code names for the rods, and naming virtual actions, and patterns made with the rods with algebraic writing. We have integrated the Cuisenaire-Gattegno approach with the 2014 National Curriculum to create algebraFirst™ software tools and a curriculum unfolding. In this workshop you will learn about how our approach meets the key aim of the new NC - that pupils and teachers can "move fluently between representations of mathematical ideas."

Workshops on algebraFirst™ July 9

We will be presenting our work at workshops at the More than the sum of the parts conference in London on July 9.

The 2014 national curriculum requires learners “to move fluently between representations of mathematical ideas.” Gattegno’s Cuisenaire resources are a proven way to meet this aim. In contrast to the traditional counting first approach Gattegno explores the algebraic structure of number before arithmetic. Mathematical ideas are experienced as concrete actions with Cuisenaire rods, virtual actions on mental images and written symbol systems. In these workshops we will discuss how to implement the cycle “concrete – virtual – symbolic” to meet the Year 1 aims. Delegates are encouraged to bring Cuisenaire rods, or tablet computers with the NumBlox app installed (iPad and Android).


Representing Functional Relationships

The study of permutations and combinations of Cuisenaire rods has proved to be a rich source of mathematical tasks motivating abstraction through algebraic symbol systems as well as mathematical generalisation. Cuisenaire-Gattegno is a unique approach that can meet the aim set by the 2014 English national curriculum, that learners “need to be able to move fluently between representations of mathematical ideas.”

In this article I take a rod permutation problem and show how teachers can use this task to support generalisation by employing a new formalism and diagramming convention that records the functional relationships between patterns of Cuisenaire rods. This convention was suggested by William Lawvere and Stephen Schanuel as an “external and internal diagram” for mappings between typed sets. (Conceptual Mathematics,1997,2004)

Getting Started With Early Algebra

In two articles, we describe how we are meeting the ambitious Key Stage 1 objectives of the 2014 mathematics curriculum through mathematical writing. The 2013 curriculum requires learners ‘to move fluently between representations of mathematical ideas.’ Children now have to study all four arithmetic operations and fractions as operators for small numbers from Year 1.

Can computer science rescue mathematics reform?

The new English mathematics curriculum continues to rely first on counting, not algebra. In an opinion piece, from the September edition of the Ring, the magazine of the graduate association of the Cambridge University Computer Laboratory, I argue that computer science in schools can deliver this essential entitlement.

Tablets of Wisdom?

Schools have experienced three major waves of computer technology over the last 30 years: micro-computers, networked electronic whiteboards and now an emerging wave of individual one-to-one iPads and Android tablets. In the past, the UK government has found it difficult to demonstrate value from technology in schools. Despite 80 per cent of schools being rated good or outstanding by Ofsted, the country’s performance in international league tables has declined. Is it possible to do better this time? Do business-led school networks have a role in promoting one-to-one learning? Will the Coalition’s less directive approach to technology procurement allow schools to experiment with different models for learning and teaching? And, if they do, how will Ofsted assess schools as they begin to embrace a new pedagogy of flipped classrooms, enquiry and project-based learning?

Preparing for Mathematics Success at Secondary School

Sociality Mathematics CIC has published the early results of its work developing an approach to formative assessment in Year 7 based on Gattegno's early algebra. A short video can be viewed here. Although there are many reports of the Cuisenaire-Gattegno approach being trialled in primary school, Fortran is the first reported study to reproduce Gattegno's findings at secondary level. The study was part funded by the Sutton Trust. The result is a successful proof of concept and a step change in the understanding of teachers and learners.

Importance of Primary Maths

Recent results in a paper by John Jerrim and Alvaro Choi suggest that, although average math test scores are higher in East Asian countries, this achievement gap does not increase between ages 10 and 16. They conclude that reforming the secondary school system may not be the most effective way for England to ‘catch up’ with the East Asian nations in the PISA math rankings. Rather earlier intervention, during pre-school and primary school, may be needed instead.

Spotted in Cyberspace

The role of Cuisenaire rods with Gattegno's textbooks is the subject of a recent blog exchange. Readers can experience this themselves by visiting the tizard widget.


Maths as language

''The growing importance of maths shows that we need to do more to make sure that children speak that language too ...... the only way to create the next generation of Turings and Lovelaces is to make fluency in the universal language of maths our top priority.'' So says Education Minister, Elizabeth Truss in her speech at the North of England Education Conference. In defining what fluency and arithmetic proficiency mean the NCETM cite the work of the Tizard network as their sole example of best practice. More on the Tizard cohort 6 can be found at the NCETM website, where a case study of four years exposure to the Cui curriculum is described by Caroline Ainsworth.


Schools as Self-Organising Systems

What can self-organising biological systems tell us about learning and teaching? A good deal, according to Enrico Coen, a plant geneticist. In ``Cells to Civilizations'' he presents a unified account of the emergence of living organisms, and highlights common principles of development across levels -- from evolution and cell development, to learning and human culture.

Structured Arithmetic?

In her review of the recent TIMMS and PISA results and findings from a recent study that shows little change in mathematics proficiency since the 1970's Elizabeth Truss, Education Minister, wrote, ``At primary level, (the new primary curriculum) will mean increased focus on arithmetic and taking it off data; requiring not only that pupils learn things like their tables earlier – at Year 4 instead of Year 6 – but also that they develop structured arithmetic, developing the foundations for algebra.''

The Cui approach is the only proven way of learning and teaching early algebra.

Introduction to the Cui approach: ATM Conference 3 April 2013

Ian Benson and Anne Haworth are offering a 3 hour workshop for primary teachers and educationists at the ATM conference in Sheffield, UK on Wednesday 3rd April

1130-1300 ATM Session C2

Part 1: Early Algebra

Gattegno maintained that we can exhaustively identify the awarenesses needed in any domain and redefine teaching as the activity which leads students to cover this ground for themselves without missing any essential steps and without wasting time. To this end he developed the Cui curriculum and related textbooks. Like the proposed UK primary curriculum, Gattegno covers all four arithmetic operations, fractions and product tables at KS1. He did this by introducing algebra as a formal language first, before number. What does algebra look like to infants? We will cover Cuisenaire code, trains, staircases, patterns, decimal fractions and percentages in practical exercises.

1600-1730 ATM Session D4:

Part 2 Metamathematics and Formative Assessment

Few primary teachers are familiar with mathematics as a language. What do teachers look for when they observe students working with rods and algebraic writing? What does Gattegno mean by equivalence and how does he harness the idea to create rich opportunities for students to learn? Reasoning with equivalence: colour, length, difference, parity, fractions as magnitudes, products. Reasoning about equivalence: sets, functions, domains, objects, arrows, permutations and combinations. Exercises with Complete Patterns. Formative assessment of student work in Years 1-6. Sessions based on eight years experience of re-introducing Cui in the Tizard network of primary schools.


Pre-algebra Centre Stage

Anne Haworth has now collated the evidence submitted to the UK Advisory Council for Mathematics Education and ACME have presented it to Government. In it ACME recommend developing a coherent pre-algebra strand in the primary mathematics curriculum. They write,

''We had asked specifically about algebra.... Many respondents said that the Programme of Study (PoS) does not provide a coherent progression towards formal algebra, one claiming that it provided a weaker foundation than the current curriculum because the procedural approach discouraged thinking before acting.

``Many respondents suggested ways in which preparation for algebra could start in Year 1, and that expectations of algebraic thinking could be even more challenging if they were based on reasoning about relations between quantities, such as patterns, structure, equivalence, commutativity, distributivity, and associativity, and models and representations of these.

``There are opportunities to be explicit about this throughout the current draft in relation to mental calculation methods and understanding direct and inverse relations.....

``Algebra in primary connects what is known about number relations in arithmetic to general expression of those relations, including unknown quantities and variables. Operations need to be thoroughly understood in order to make this connection. The only generalising currently explicit in the PoS relates to pattern sequences and not other forms of relations.

``A coherent developmental strand for algebra should be made explicit, making clear the connections between knowledge of number, mental methods, generalizing, and representing relations between quantities and unknowns.'' (part 2, page 3)
