(Kaieteur News) – If you think Guyanese children are failing in math, check their parents’ math skills. In Guyana, the national mathematics assessment at the primary level (NGSA) is 55.51%, and at the secondary level (CSEC), it is 32%. In previous years, the result was far below. The ministry interventions include providing students with free scientific calculators, geometry sets, graph books, organised past papers, and specialised videos on the Guyana Learning Channel. I am putting it to you that 44% of NGSA and 68% of CSEC students who fail in mathematics most have dyscalculia.

Dyscalculia is a specific learning disability that affects a person’s ability to understand, learn, and perform mathematical concepts and calculations. It is often described as “math dyslexia,” although it is a distinct condition with its own characteristics.

Students with dyscalculia have above-average intelligence yet experience significant difficulties with number-related tasks. Learning disabilities do not affect intelligence and are not a measure of intelligence. Learning disabilities refer to a non-traditional learning method that the education system needs to understand and support. It is part of the neurodivergence category.

In Guyana, where academic success is often measured heavily through examinations and mathematical performance, students with dyscalculia are often misunderstood as lazy, careless, inattentive, or lacking ability. Without proper identification and support, these students frequently experience frustration, low self-esteem, anxiety, and poor academic outcomes.

WHAT IS DYSCALCULIA?

Dyscalculia is a neurodevelopmental learning disorder that affects the brain’s ability to process numerical information. Dyscalculia is part of a group of learning disabilities, such as Dyslexia and Dysgraphia. Individuals with dyscalculia struggle with understanding numbers and quantities, learning basic arithmetic facts, recognising numbers, place-value concepts, mental mathematics, sequencing numbers, mathematical reasoning, time concepts, money management, estimation, and measurement. Dyscalculia occurs across all cultures, languages, and socioeconomic groups.

COMMON SIGNS 

In early childhood, there was difficulty learning to count, trouble recognising numbers, difficulty understanding “more” and “less” or the signs. There are problems sorting objects by quantity and difficulty learning number songs and rhymes.

In primary school, persistent finger counting, there is difficulty remembering addition and multiplication facts. Confusion with mathematical symbols, difficulty understanding place value and slow mathematical processing are common.

In secondary school, there is difficulty with fractions and percentages, problems understanding algebra, difficulty interpreting graphs and trouble solving word problems. Poor estimation skills and difficulty managing time and money are also common.

CAUSES

Dyscalculia results from differences in brain development and functioning rather than poor teaching or lack of effort. Learning disabilities are co-occurring with other developmental disorders and learning disabilities like ADHD, Dyslexia, Motor Disorders, Communication Disorders, etc. The origin is 75% geneti; neurological differences in the number processing areas of the brain. Dyscalculia is not caused by laziness, poor parenting, low intelligence, or lack of motivation.

IMPACT ON LEARNING

Guyanese students and adults experience consistently poor mathematics performance, difficulty passing mathematics examinations, challenges in science and technical subjects. They also experience difficulty understanding financial literacy concepts and tend to have limited confidence in academic settings.

Emotional impact is mathematics anxiety includes fear of failure, shame and embarrassment, low self-esteem and feelings of being “stupid”. These repeated negative experiences are what is very crippling and lead students to avoid mathematics entirely or to approach it with fear, which then produces the negative results.

Social impact is so significant that students compare themselves negatively to peers. Avoid classroom participation. Become withdrawn and develop behavioural problems due to frustration.

Long-term impact without support for dyscalculia affects career opportunities and financial management, daily living skills, employment performance and hampers opportunities for higher education.

CHALLENGES

Several factors make dyscalculia difficult to identify and support in Guyana. Limited Awareness: Many parents and educators have little formal training in learning disabilities. An examination-oriented culture, with a strong emphasis on NGSA preparation, CSEC Mathematics, and CAPE Mathematics, increases stress for students with dyscalculia.

With large class sizes, teachers may struggle to provide individualised instruction. Due to limited assessment resources, formal psychoeducational assessments may not be readily available across all regions. Students with stigma are sometimes labelled rather than receiving appropriate support.

STRENGTHS

Although mathematics may be challenging, many students possess significant strengths.

They may excel in creativity in art and design, music, leadership, sports, and problem-solving in non-mathematical situations or interpersonal relationships. Educators should focus on both strengths and challenges.

Teaching Math to students with Dyscalculia

1. 1. Build Mathematical Understanding before Memorisation.

Students should understand concepts before learning procedures. For example, instead of memorising, allow students, even at ages 8, 12, or 16, to use counters, blocks, or objects to visualise the relationship. Use Concrete–Representational–Abstract (CRA) Teaching Concrete Stage Use, counters, bottle caps, beans, blocks and coins. Students will physically manipulate objects, which is significantly helpful.

Representational Stage. Use drawings, number lines, diagrams and pictures.

2. Abstract stage moves to mathematical symbols only after understanding develops.
3. Use Multi-Sensory Learning. This concept involves seeing, hearing, touching and movement for example drawing numbers in sand, using number tiles, clapping counting patterns and walking along number lines.
4. Avoid overwhelming students. Break lessons into small steps to understand quantities. Mastery should precede the introduction of new skills.
5. Use Visual Supports. Helpful tools include hundreds of charts and number lines. Place-value charts. Colour coding and other graphic organisers. Visual supports reduce cognitive load.
6. Encourage Verbal Reasoning. Ask students, “How did you get that answer?” “What strategy did you use?” “Can you explain your thinking?” This strengthens mathematical understanding.
7. Provide Frequent Practice. Practice should be short, repetitive, structured and success-oriented. Ten minutes daily is often more effective than one hour once weekly.
8. Reduce Mathematics Anxiety. Teachers should normalize mistakes. Praise effort. Avoid public embarrassment. Celebrate small successes. A supportive environment improves learning significantly.

EFFECTIVE CLASSROOM TECHNIQUES

Number lines help students visualise numerical relationships.

Real-life mathematics connects lessons to shopping, markets, farming, sports statistics, and household budgeting. These relevant examples improve understanding. Technology is also a useful tool, including calculator support and interactive mathematics software. Educational apps. Digital number lines as technology compensates for processing difficulties.

Teachers should provide extra time on tests. Allow calculator use when appropriate. Reduce unnecessary copying. Provide step-by-step instructions. Give worked examples. Use oral explanations. Provide visual aids. Break assignments into smaller tasks. These accommodations promote fairness rather than giving unfair advantages. Avoid criticism and punishment for struggles in mathematics. After all, your child likely got it from you or the other parent. Use everyday opportunities to teach number concepts. Practice counting during shopping trips. Have this child involved in real-life math activities, such as shopping and paying bills. Use games involving numbers. Celebrate effort rather than perfection. Communicate regularly with teachers.

Building Inclusive Schools in Guyana can improve outcomes by training teachers about dyscalculia. It is encouraged that the education sector develops an early screening programme at the nursery level. Many Guyanese students with dyscalculia remain unidentified and unsupported, leading to unnecessary academic struggles and emotional distress. Through early identification, teacher awareness, multi-sensory instruction, concrete learning experiences, emotional support, and inclusive educational practices, students with dyscalculia can develop mathematical competence, confidence, and success.
