# New Discovering Mathematics Textbook 1A

New Discovering Mathematics is a series of textbooks written with a learner-centric approach that builds upon the knowledge and skills learnt in primary school. It is based on the latest O-level Mathematics syllabus implemented from 2020 by the Ministry of Education of Singapore.

The emphasis of this series is on empowering students to learn mathematics independently and effectively. Depending on the topics covered, different approaches are used to present different concepts to facilitate students' understanding.

**New Discovering Mathematics **is organised into three content strands: **Numbers & Algebra, Geometry & Measurement and Statistics & Probability.**

This series includes clear and illustrative examples, class activities and diagrams to help students understand the concepts and apply them.

**Key features:**

**Chapter Opener**

Introduces a chapter by providing real-world context, focusing on the relevance of mathematics in our daily lives.**Activity**Enhances students' learning experiences through exploration and discovery by guiding them through relevant tasks.**Worked Example**

Illustrates the steps in solving mathematical problems to help students understand a concept or skill. Analysis in difficult problems guides students in unpacking the information and making sense of it.**Practice Exercise**

Provides exercises with different difficulty levels:**Basic, Intermediate and Advanced**for further practice.*(Answer key included at the back of book)***Let's Sum it Up**

Highlight important concepts, formulae, properties and rules for quick revision.**Review Exercise**

Provides a further exercise to reinforce understanding and consolidate learning for each chapter.**Revision Exercise**Tests mastery of what has been learnt with problems that integrate concepts and skills taught across topics.**Problem Solving Task**Includes non-routine problems to develop students' problem-solving skills with prompts to guide students using Polya's 4-step approach.**Problems in Real-world Contexts**Gives students opportunities to explore, model and solve problems in real-life situations, allowing them to realise the relevance and utility of mathematics in our daily lives.*ADDITIONAL!***Professional's Voice**

Presents the connections to Big Ideas in a mathematics and provides opportunities to explore how certain concepts relate to and can be applied to other concepts.**Core Vocabulary**Lists down essential mathematical terms introduced in the chapter.**Coding**Provides coding opportunities to support development of computational thinking.**Discuss**Poses questions to extend students' learning and encourage communication of mathematical concepts and ideas.**Spotlight**Highlights important information to take note of**Recall**Prompts to recollect concepts and definition learnt previously.**Extra Info**Introduces scientific, historical or fun mathematical facts related to the topic
