Event: Mathematics Festival ATM/MA

Location: National STEM Center, University of York

Date: Saturday 15 September 2018

Session: A03 (Classroom 3)

Time: 1100-1155

Caleb Gattegno's contribution to mathematics education ranged from innovation in the school curriculum ("Algebra First") to a theory of learning - the Science of Education.

Where a "bit" might be said to be a unit of study in information theory, a gene in biology, or an atom in physics -- Gattegno's scientists of education study an "awareness."

In these two articles developed as part of booklets with the ATM Science of Education Working Group, I look at how exercises with the rods can stimulate various mathematical awarenesses, whose "temporal hierarchy" is recorded in the pathways in the Curriculum Graph.

The reader can try the exercises here.

Location: University of Warwick (British Congress of Mathematics Educators Session D34)

Dates; Wednesday 4 April, Time: 14:00-15:30

Facilitators: Anne Crosby, Ian Benson

With his Curriculum chart Gattegno demonstrated how a study of permutations and combinations of
Cuisenaire rods can animate an enriched mathematics curriculum, extending from KS1 to KS5. The chart is
organised as a directed acylic graph: its nodes labelled by concepts, and its edges representing a temporal
hierarchy. Each root corresponds to the study of a restriction on the pattern of all permutations equivalent in
length to a rod. This is a practical session using both Cuisenaire rods and a related software system. We will
explore the mathematics and computer science that teachers need to know to use the chart.

The chart is reproduced on page 6 of Working with the rods and why. An ATM open resource.

Facilitator: Rachael Rudge

Location: Kesgrave High School (15/11) Tudor C of E Primary Academy (Sudbury) (16/11)Time: 13:30-16:00

The Norfolk & Suffolk Maths Hub are running a FREE 2 day course looking at introducing and developing algebra in Key Stage 1 classrooms. The course is being run by Rachel Rudge who started on this workgroup with the Maths Hub in 2015/2016 and is continuing this further this academic year. The course will be based on introducing Cuisenaire rods and the concepts of equivalence, addition and difference and how to write equations using the letters to represent the rods and the plus, minus and equals sign. There will be a gap task followed by a second event in February. This will feature feedback from teachers on the gap task and will look at the concepts of multiplication, division and fractions as operators using the rods. The rods will be assigned numbers for the second session.

Facilitators: Jenny Cane, Ian Benson

Location: Bursted Wood Primary School

Time: 16:00-18:00

We are pleased to announce a twilight event on Early Algebra for KS1 teachers and mathematics co-ordinators. Places are available on a first-come, first-served basis here..

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.

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.

Session H3: Thursday 31st March 1600

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.

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."

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).

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)

Title: Co-operative Maths Reform

Speaker: Ian Benson

Event Date: 13/11/2014 (10:00-14:00)

Venue: Birmingham, UK

Abstract:

The 2014 mathematics curriculum requires learners to move fluently between concrete, symbolic and numerical representations of mathematical ideas. Sociality Mathematics CIC is a network of primary and secondary schools who are working together to create high quality resources to meet this end. In this session you will learn how colour-coded Cuisenaire rods are being used to teach all four arithmetic operations and fractions as operators from Year 1, and how Gattegno's "Mathematics with Numbers in Colour" serves as an introduction to computational thinking.

Title: Using the Gattegno/Goutard approach to Cuisenaire rods to enable children to discover the structure of maths for themselves

Speaker: Caroline Ainsworth

Event date: 29/11/2014 (10:00-13:15)

Venue: Manchester, UK

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.

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.

The attached presentation was discussed at the annual conference of the UK Association of Teachers of Mathematics (ATM) in Sheffield on Wednesday 3rd April 2013. The video links in the presentation are as follows:
