Language and maths: teaching EAL pupils

Language and maths: teaching EAL pupils

As a Year 2 teacher in a Thai–UK curriculum school in Bangkok, most of my pupils are EAL (English as an Additional Language) learners. However, unlike those I taught in London, my Thai pupils find mathematics to be fun and seem to struggle less with understanding mathematical concepts.

Not only do my Thai pupils have to learn mathematical concepts but they also need to learn mathematical terminology in English!

One clue to their conceptual understanding can be found in the unique differences between the Thai and English languages.

As we can see, Thai pupils make use of place value in order to construct numbers linguistically. Rather than saying ‘fourteen’ or ‘thirty’, they say ‘ten and four’ (10 + 4) or ‘three tens’ (3 × 10). By using place value they can see how numbers are combined to make larger numbers, and even how multiplication functions as repeated addition. For example, 40 is spoken as ‘four-tens’ or ‘4×10’.

This relationship between language and place value can be further reinforced by making use of manipulatives and pictorial representations in order to understand number sentences.

 

What about fractions? Does language play a role? Yes!

There is a consistent structure and pattern to how the Thai language constructs fractions. This reinforces the part–whole relationship (Saed) and the relationship between the numerator and denominator, as one in which the whole is ‘divided’ or partitioned (Suan). The Thai language has only one name for each fraction.

Compare this to the English language, which has multiple ways of describing the same fraction.

The relationship between numerator and denominator and how this relationship is inextricably linked with whole-part relationship can be visualised or experienced using manipulatives (e.g. Dienes blocks) or pictorial representations. By using manipulatives, white boards for pictures and reinforcing ‘part’, ‘piece’, ‘fraction’ and ‘whole’ when referring to fractions, I enabled a clear connection between Thai (first language) and English (second language). This certainly was a powerful scaffold that allowed my Year 2 pupils to compare and order fractions.

 

Reflection

Jerome Bruner believed that knowledge is socially constructed and Lev Vygotsky hypothesised that language plays a crucial role in that social construction. After teaching Thai EAL pupils for two years, I have seen how language plays an important role in how we perceive mathematical relationships.

The English language has unique features that sometimes make it difficult for EAL learners to understand these relationships.

In other words, what is thirteen? Forty? A Quarter?
The answer: ‘Ten and three’, ‘four tens’ and ‘one part of whole, one divide four’.

If, as teachers, we understand how our students construct knowledge in their native tongue then this can help us differentiate, personalise and scaffold learning whilst ensuring second language acquisition.

So, how can we avoid ambiguous mathematical terminology (e.g. two thirds, halves, one fourth, quarters) in early maths acquisition in majority English language learning environments?

  • I suggest we might use a common mathematical language for all fractions (e.g. one over two, two over three) in order to scaffold learning, and use manipulatives to reinforce this relationship.
  • We should keep language as simple and consistent as possible at the initial stages of learning new maths concepts such as fractions. Once the language is consolidated (e.g. ‘one over two’), we can teach different terms (e.g. 'one half, halve').

About the author

Gabriel Flores teaches in Amnuay Silpa School, a UK–Thai curriculum school in Bangkok. Before moving to Bangkok in 2017, he taught at Heronsgate Primary School in London. Gabriel would like to thank his colleague, Ajarn Warunee Poonsawad, for her help explaining Thai mathematical terminology and pedagogical practices. This informed his understanding of how their Thai EAL children understand maths.

The theme of linking language to the structure of mathematics is drawn on in the NCETM primary professional development materials. In Year 1* children are encouraged to ‘dual count’ when learning to count in tens (‘no tens, one ten, two tens...’ as well as ‘zero, ten, twenty…’), and when learning the ‘teen’ numbers (‘one ten one, one ten two, one ten three…’ as well as ‘eleven, twelve, thirteen…’). Teachers are encouraged to be explicit about when number names suggest the structure (e.g. 'eighty, eighteen') and where they are more opaque (e.g. 'twenty, eleven').

Once children understand unit fractions 1/3 and they draw a fraction circle to represent this relationship. Then introducing non-unit fractions (2/3 or 3/4) is intuitive. In the above example, Lulu and Elliot, children compare non-unit fractions because they can 'see' the relationship by drawing a fraction circle (in fractions with like denominators). In fact, they can state that 1/2<1 because they have been taught that 1=2/2. Again, as long as children can read fractions and have used different manipulatives (Diennes blocks, interlocking blocks, numicons, whiteboards etc) to deepen their understanding; they should find the transition to non-unit proper fractions with like denominators relatively smooth. Again, you can follow a similiar approach when introducing improper fractions 4/3. For example, by using simple word problems, manipulatives and whiteboards. Of course, I would try not to use advance equations or multiplication so as to focus on understanding the logic and relationship between whole-part. I hope this helps.

Auto correct ‘you are’ We have been working on fractions of amounts.

As a teacher of year 4 children in the uk I found your insight into teaching fractions very interesting. I realise your are teaching year 2 and are introducing the concept of unit fractions. I love the idea of one divided by 6. However I wonder how you might interpret and move on to non unit fractions when the children have to multiply by the numerator as any help with the language of maths would be valuable.

I am in awe of children learning English and receiving an education in a second language
