Most Secondary Three students face the following challenges with Secondary Elementary and Additional Mathematics:

- Shaky foundation for Lower Secondary Mathematics, especially in Algebra
- Having to learn new topics while trying to grasp old concepts
- Solutions tend to be long and more complex
- Some theorems at isolated and not built on prior topics
- Fall behind due to the fast pace of teaching in school

From our experience…
- Many Secondary Three students are fighting two battles:
       ➝ One, to sort out confusion about Lower Secondary mathematical concepts
       ➝ Two, to understand new topics that are more complex
- Students who are not strong in Mathematics soon begin to panic because Additional Mathematics is a new subject, with new mathematical concepts
- Students are demoralised because solutions are much longer and more complicated with little scaffolding from the questions
- As a result, some students experience a massive drop in grades at Secondary Three

Why your child needs help with Secondary Three Mathematics right now

➡️ While the new Secondary Three mathematical concepts in Elementary and Additional Mathematics may look daunting, clear guidance and tips from a good coach can point students in the right direction.

➡️ Preparing for O Level examinations should start at the beginning of Secondary Three, not Secondary Four.

At Cognitus Academy, we offer weekly regular Mathematics lessons and short intensive programmes to help students at every level of readiness.

Secondary 3 Regular Mathematics Programme

At Cognitus Academy, our students will get to develop a keen interest in abstract mathematical concepts, learn how to present the solutions coherently and strengthen their skills and techniques in solving the questions efficaciously.

Conquering Mathematics through the DEPTH Framework

Our curriculum methodology provides 5 key elements to help students learn effectively during our Mathematics lessons.
This framework evaluates students’ current ability, helps to clear doubts, and expose students to exam-based questions.

Our curriculum structure includes asking probing questions in class to encourage students to explore, discover and build their confidence in Mathematics.

Deepened Curriculum, Heightened Learning

Apart from what is learnt from the school syllabus, students will develop a deeper insight into the curriculum. Understanding the core concepts deeply will also enhance students’ ability to apply heuristics to handle higher-order thinking questions.

Eliminated Errors and Misconceptions

Drills and practices develop fluency and heighten students’ awareness of their carelessness when solving Mathematics questions. Training students to understand their own tendencies greatly improves the accuracy of their calculations.

Practical and Authentic (Real World) Mathematics Teasers

Learning out of real-world context requires abstract thinking. This requirement stumps some students who need to see concrete examples. Students will learn to link Mathematics to authentic real-world problems, enhancing their number sense and conceptual development.

Think Critically and Mathematically

Thinking critically requires habits of mind and problem-solving skills. Merging critical and mathematical thinking makes the learning of Mathematics exciting and engaging. Learning Mathematics in this way unlocks the fun and challenging aspects of the subject.

Honed Precision

With carefully selected tasks for each lesson, students will learn how to be quick and accurate in their computations. Beyond procedural accuracy, students will also develop structural thinking that provides repeatable steps for analysing non-routine questions.

Good strategies will only be able to transform students' results if they are motivated

Your child may have been attending Mathematics tuition but has not been seeing improvement.

Why is that so?

The fact is, the lessons your child has been attending are not pitched according to his/her level of readiness.
If students are unable to grasp the lesson, forcing them to finish their Maths assignments demotivates them.
If the lessons are too simple, your child will be bored and unmotivated.

At Cognitus Academy, our programme is crafted to MEET every child’s level of readiness and motivate them to achieve their FULL potential.

Through our own passion for the subject, our trained and experienced teachers ignite students’ LOVE and INTEREST in Mathematics .

Secondary 3 Mathematics Power Up Programme

In our experience, many students find A Maths difficult because they are already weak in Algebra and other big topics. Losing confidence for Maths at the start of Sec 3 may spiral downwards to greater fears and worry. Therefore, it is important to level up for A Maths right now and start building towards A1 for the subject.

To support Sec 3 students who need a boost in A Maths, our team of ex-MOE teachers, exam markers and Heads of Department is pleased to launch the Sec 3 A Maths Power Up Programme.

➡️ Conceptual Alignment

Each lesson will focus on the interconnection between related topics. Students will develope clear understanding of the core knowledge within each topic through our concise summary. In addition, students will learn the key skills that help them confidently solve commonly-tested questions and maximise the marks scored through clear presentation. More importantly, students get to consolidate the learning through hands-on practice with the teacher’s coaching.

Frequently Asked Questions

How is your Secondary Mathematics programme different from other Mathematics tuition programmes?
Cognitus Academy applies the DEPTH Framework where we ensure that learning does not simply come from drill and practice. DEPTH Framework focuses on real-life application of Mathematics and problem-solving skills. We follow a structured lesson plan where students apply their knowledge in bite-size practices and move on to problem sums to build their confidence. Students who are strong in Mathematics will be stretched through practices with non-routine questions.
How does my child build up his/her foundation in Mathematics?
One key foundation in the DEPTH Framework is the ability to connect mathematical concepts with real-life examples. Starting from the concrete application of Mathematics, your child can then develop understanding in using abstract (numbers and models) forms of presentation for their interpretation and solution of each question. Our experienced teachers will also pace your child towards success by helping them to create small victories that lead to big success in Mathematics.
If my child has Mathematics questions from school that he is unable to solve, can he consult the centre’s teachers?
Certainly! The purpose of conducting a small-class Mathematics tuition is to create a structured, yet individualised learning experience for our students. Please send all your child’s questions from school and individual practices our way.
How is a typical lesson like?
Each lesson runs for 120 minutes.
– For the first 15 minutes, we will go through corrections from previous homework. This step is critical in helping students correct misconceptions.
– The remaining part of the lesson will focus on problem sums where students are taught effective and efficient steps to solve higher-order thinking questions.
What is the difference between IP/IB and O level Mathematics?
90% of the IP/IB Mathematics topics are similar to that of the O level Mathematics. Our programmes are created to teach our students the concepts and to stretch them further to higher order thinking. Hence, IP/IB students will continue to feel engaged during lessons while the O level students potential are stretched.
