# Dyscalculia In Schools: A Guide To Identifying And Supporting Students With ‘Math Dyslexia’

**Dyscalculia can make learning math at elementary and middle school particularly difficult. However, both teachers and parents can support children through various strategies when covering areas such as multiplication facts, number facts, telling time and word problems.**

### What is dyscalculia?

Dyscalculia is a specific learning difficulty in mathematics that affects around 5% of the population. It is better thought of as difficulty with arithmetic skills and numeracy, rather than in mathematics learning as a whole, as there may be no difficulty with topics such as shape or geometry.

Put simply, dyscalculic people have no clear understanding of quantity. They lack number sense, which means that they have a hard time comprehending our number system and how numbers relate to each other.

‘Developmental dyscalculia’ is present from birth and is a life-long condition that is unrelated to IQ. This is compared to ‘acquired dyscalculia’, which might have been the result of something like a brain injury.

Although there is much less neuroscience research surrounding the prevalence of dyscalculia, compared to other learning disorders (such as dyslexia), it is legally recognized as a specific learning disability.

This means that schools have an obligation to identify learners with dyscalculia and to put in place reasonable adjustments to ensure that these children have the same opportunities as every other child in the class.

Children may be given extra time in tests or exams, or they may have individual or small group learning support. All staff should be aware of the difficulties that dyscalculic learners experience so that they can adjust their teaching to meet the needs of these children.

The indicators, manifestations or symptoms of dyscalculia can be thought of in terms of four different areas of learning:

- Core number
- Reasoning
- Memory
- Visual-spatial

#### Core number

This particular subtype of dyscalculia will lead to difficulties with:

- Basic number sense
- Estimating and rounding
- Appreciating numerical quantity
- Working with mathematical symbols
- Place value
- Placing numbers on a number line

**Basic number sense**

Number sense is our ability to be flexible with numeracy and to understand how numbers relate to each other. Learners with poor number sense rely on rote learning and applying procedures. They rarely use reasoning and generalizing as a means to tackle mathematical tasks.

For example, a child with good number sense would see 29 + 30 + 31 as 3 x 30, as this is a quicker way of working out the answer. A child with poor number sense would not see the relationship between these numbers and would probably follow the standard procedure of column addition.

**Estimating and rounding**

Many learners with math impairments are reluctant to find an estimate before calculating an answer, but most will have some idea of the expected magnitude of the answer. Those with a core number deficit will literally have no idea what the answer should be, so will accept any answer that they get, however implausible it might be.

**Appreciating numerical quantity**

As well as having difficulty in estimating, these learners will also find it hard to assess numerical quantity. Learners with dyscalculia have difficulty matching the numerical symbol to the numerical quantity. They also have difficulty comparing numerical quantities.

For example, understanding that 370 is ten times as large as 37 and ten times smaller than 3700. In severe cases, they may find it hard to understand even basic comparisons, such as 8 being more than 6.

**Working with mathematical symbols**

The symbols that we use in math are an arbitrary shorthand to help us when we are recording mathematical ideas. Often, learners with core numeracy difficulties find it very hard to understand and use mathematical symbols.

**Place value**

Place value is an abstract concept and one that many learners struggle with. For example, going through a stage of writing 1002 for 102 (one hundred and two). However, for learners with dyscalculia, place value can be a concept that they struggle with year on year.

**Placing numbers on a number line**

Another difficulty these learners have is with placing numbers on a number line. This stems from the children not having an appreciation of how numbers relate to each other.

#### Reasoning

This particular subtype of dyscalculia will lead to difficulties with:

- Understanding mathematical concepts and relationships
- Generalizing and transferring information
- Understanding multiple steps in complex procedures/algorithms
- Problem-solving and decision making

**Understanding mathematical concepts and relationships**

For many learners with difficulty in this area, math is all about remembering procedures, multiplication facts and number bonds. They have very little understanding of the patterns and connections in math.

For example, understanding the repeated addition and area models of multiplication or appreciating that we can use subtraction to check addition calculations.

**Generalizing and transferring information**

Being able to make connections in math can make life much easier as learners can use what they already know to work out something new.

For example, if you know that 4 + 5 = 9 then you can generalize this information to help work out 40 + 50, or 4 + 4 etc. Learners with poor mathematical reasoning will not see these connections and will treat each calculation as completely new and discrete from anything they have met before.

**Understanding multiple steps in complex procedures/algorithms**

Learners with poor reasoning skills invariably have to rely on their memory when tackling math problems. Some procedures in math can be complex, involving multiple steps, and if you are relying solely on memory rather than understanding, it can be very easy to make mistakes and forget steps.

**Problem-solving and decision-making**

Learners with poor reasoning skills will find it hard to solve problems in different ways and will tend to use the same method every time. This can be a very inefficient way of approaching math problems and effectively means that they are doing a harder version of math.

For example, 2000 x 0.25 is much easier to calculate if you think of 0.25 as being one quarter, and then you can just divide 2000 by 4.

#### Memory

This particular sub-type of dyscalculia will lead to difficulties with:

- Remembering and recalling numerical facts
- Understanding and recalling mathematical terminology
- Understanding word problems
- Performing mental calculations accurately
- Keeping track of the steps in problem-solving

**Remembering and recalling numerical facts**

For example, recall of number bonds to ten or multiplication facts. Without understanding how numbers relate to each other, all we can rely on is our memory to help us to remember these facts.

For some learners, their short-term, working, and long-term memory can be compromised and this can lead to difficulties in math – particularly in mental calculations.

**Understanding and recalling mathematical terminology**

Many words in math are technical and not commonly used in daily language, including terms like numerator and denominator. This can make math inaccessible for many learners.

Conversely, there are terms used in math that also have frequent use in daily language and multiple meanings, and this can be a great cause of confusion. For example, words like ‘table’, ‘product’ and ‘degrees’.

**Understanding word problems**

As well as getting to grips with the mathematical language, learners also need to understand how this relates to real life situations and to be able to interpret the math behind complex word problems.

This requires the learner to be able to store verbal information in their working memory while they access the math that relates to that information. For learners with poor memory, this can be very challenging.

**Performing mental calculations accurately**

Mental arithmetic places great demands on the working memory, with pieces of information having to be held while we work on something else, and then correctly retrieved and integrated back into the original question.

**Keeping track of the steps in problem-solving**

Again, this will place huge demands on working memory. The learner will need to hold information in mind while following the steps of a procedure, and also make sure that the steps are carried out in the correct order.

#### Visual-spatial

This particular subtype of dyscalculia will lead to difficulties with:

- Recognizing and understanding symbols
- Interpreting visual representations of mathematical objects
- Interpreting graphs and tables

**Recognizing and understanding symbols**

For example, many learners with dyscalculia confuse x with +. They can also have difficulty understanding commonly used symbols such as ‘=’. Many learners think this sign means ‘the answer is’.

We often present equations in a way that perpetuates this misunderstanding, writing 2 + 3 = 5, rather than 5 = 2 + 3. This leads the learner to believe that ‘=’ means ‘the answer is’ rather than ‘equals’.

**Interpreting visual representations of mathematical objects**

Having poor visual-spatial skills will make it hard to recognize the net of a square, or be able to visualize and describe a 3D shape.

**Interpreting graphs and tables**

Dyscalculic learners with poor visual-spatial skills have difficulty reading information from tables or understanding graphs and how to interpret them. They also have difficulty understanding scales on axes and in measuring.

Does dyscalculia correlate to other learning difficulties?

Dyscalculia rarely occurs in isolation and often co-occurs with other learning difficulties such as dyslexia, dyspraxia, dysgraphia, ADHD and auditory processing.

### How to diagnose dyscalculia

Initially, a screener may be administered to look for a ‘risk factor’ of dyscalculia, and this can inform the decision as to whether to carry out a full diagnostic assessment or not. Assessments and dyscalculia diagnosis will be explored further in the second blog in this series.

### Strategies to help with dyscalculia

- As mentioned in the first paragraph of the blog, group or individual learning support can help with dyscalculia, such as the one-on-one online math instruction offered by Third Space Learning!
- Use concrete materials, such as Cuisenaire rods, ten frames, two colored counters and base ten materials.
- Spend time exploring these and don’t take them away too soon; they will help to develop the child’s understanding.
- Play games with dice and dominoes so that the child can recognize common dot patterns; this will help with subitizing and seeing the relationship between one number and another.
- Try to encourage the child to use more efficient calculating strategies, such as counting on rather than counting all.
- Encourage the child to visualize the math by drawing diagrams and using concrete materials to model the math.
- Make the math practical and as multisensory as possible; try to avoid worksheets.
- Adopt a little and often approach; repetition and ‘overlearning’ will help.
- Use mathematical language as much as possible and encourage the child to do the same.
- Give multiplication facts and number bonds to reduce the stress of having to remember these facts.

### Dyscalculia summary

Dyscalculia is not the same as more general difficulties with math that many children experience, such as difficulty with place value or fractions. It is a specific learning difference, affecting our ability to assess numerical quantity, to understand our number system and the relationships and connections in math.

The main indicators of dyscalculia are:

- An inability to subitize even very small quantities
- Poor number sense
- Magnitude processing difficulty
- Inability to generalize
- Poor memory for facts and procedures
- An inability to estimate whether a numerical answer is reasonable
- Immature strategies (such as counting all instead of counting on)
- Inability to notice patterns

### Actionable takeaways for dyscalculia

- Use a wide range of concrete manipulatives in a way that supports visualization and understanding.
- Don’t be in a hurry to get through masses of content.
- Make sure that the basics are fully embedded.
- Play games that reinforce mathematical concepts to keep up motivation.
- Try to move children on from the counting trap, by developing reasoning and understanding of mathematical relationships.
