introduction the vision of the country to become an industrialised nation by the end of the second decade can be achieved through a society that is educated and competent in the application of mathematical knowledge to achieve this vision it is important that the society must be inclined towards mathematics therefore problem solving and communicational skills in mathematics have to be nurtured from an early age so that effective decisions can be made later in life mathematics is instrumental in the development of science and technology as such the acquisition of mathematical knowledge must be intensified so as to create a skilled workforce as a requirement for a country in achieving a developed nation status in order to create a k-based economy research and development skills in mathematics must be instilled at school level based on the national education policy and the 2020 vision the mathematics curriculum has been reviewed and revised the rationale behind this move is the need to provide mathematical knowledge and skills to students from various backgrounds and levels of ability therefore it is the country s hope that with the knowledge and skills acquired in mathematics 1 students will be able to explore discover adapt modify and be innovative in facing ongoing changes and future challenges acquisition of these skills will help propel them forward in their future careers thus benefiting the individual society and the nation the mathematics curriculum kbsm is a continuum from form 1 through form 5 the content is categorised into three interrelated areas these are numbers shapes and spaces and relationships this categorisation is based on the fact that in any situation it is imperative that a person has knowledge and skills related to counting be able to recognise shapes and measurements as well as recognise relationships between numbers and shapes aim the mathematics curriculum for secondary school aims to develop individuals who are able to think mathematically and who can apply mathematical knowledge effectively and responsibly in solving problems and making decision this will enable the individual to face challenges in everyday life that arise due to the advancement of science and technology.

emphases in teaching and learning this mathematics curriculum is arranged in such a way so as to give flexibility to teachers to implement an enjoyable meaningful useful and challenging teaching and learning environment at the same time it is important to ensure that students show progression in acquring the mathematical concepts and skills in determining the change to another learning area or topic the following have to be taken into consideration · · · the skills or concepts to be acquired in the learning area or in certain topics ensuring the hierarchy or relationship between learning areas or topics has been followed accordingly and ensuring the basic learning areas have been acquired fully before progressing to more abstract areas 1 problem solving in mathematics problem solving is the main focus in the teaching and learning of mathematics therefore the teaching and learning process must include problem solving skills which are comprehensive and cover the whole curriculum the development of problem solving skills need to be emphasised so that students are able to solve various problems effectively the skills involved are · understanding the problem · devising a plan · carrying out the plan and · looking back at the solutions various strategies and steps are used to solve problems and these are expanded so as to be applicable in other learning areas through these activities students can apply their conceptual understanding of mathematics and be confident when facing new or complex situations among the problem solving strategies that could be introduced are · · · · · · 4 trying a simple case trial and improvement drawing diagrams identifying patterns making a table chart or systematic list simulation the teaching and learning processes emphasise concept building and skill acqusition as well as the inculcation of good and positive values besides these there are other elements that have to be taken into account and infused in the teaching and learning processes in the classroom the main elements focused in the teaching and learning of mathematics are as follows:
