Maths Carnival Book 1 by Alston Education

MATHS The Maths Carnival series is developed for pupils who go to CBSE-affiliated schools to help them achieve the learning outcomes of the latest national curriculum. Maths Carnival builds a strong foundation in pupils through the use of sound pedagogical principles. Adopting the popular Concrete Pictorial Abstract approach widely used in the Singapore mathematics curriculum, pupils are introduced to new concepts through concrete manipulatives and engaging pictorials before they are led to see their abstract symbolic representations. This allows pupils to have a deeper understanding of key mathematical concepts, thus motivating them to learn. BOOK 1

Content is clearly structured across the levels to ensure a gradual build-up and review of skills as pupils progress up the levels. At the same time, emphasis is given on developing pupils’ creativity, critical thinking and problem-solving skills.

The key features of the book are: ✔ Graduated content ensuring logical progression of learning ✔ Clear presentation of key mathematical concepts with solved examples ✔ Plenty of practice exercises ✔ Hands-on maths activities to promote peer interaction and collaborative learning ✔ Ample skill-based questions to develop various skills for applying mathematics in daily life ✔ Formative and Summative assessments mapped to learning outcomes ✔ Real-life application of mathematical concepts

PREFACE The Maths Carnival series is developed for pupils who go to CBSE-affiliated schools to help them achieve the learning outcomes of the latest national curriculum. Maths Carnival builds a strong foundation of the subject through the use of well-researched and sound pedagogical principles. Adopting the popular Concrete Pictorial Abstract approach widely used in the Singapore mathematics curriculum, pupils are introduced to new concepts through concrete manipulatives and engaging pictorials before they are led to see their abstract symbolic representations.This allows pupils to have a deeper understanding of key mathematical concepts, thus motivating them to learn. The formative and summative assessments allow for continual evaluation of pupils’understanding of concepts.These outcomebased exercises aim to test their understanding and application of mathematical concepts and related skills to solve real life problems.

Welcome to Maths Carnival! Here, learning mathematics has been made a joyful experience with hands-on activities and challenging exercises. Most activities have been designed on the theme of carnival. The different sections are indicated by the relevant signboards: • • • •
