At key stage 1 (ages 5-7), the national curriculum requires students to be taught problem solving skills, counting and pattern & sequence work. Addition and subtraction operators are also introduced in years 1 and 2 with multiplication and division further into year 2 and 3. At this stage students get the grounding required to be able to solve linear equations. What they experience as being similar to this will be a word problem requiring them to find an unknown number which added to another will give the required total. Any form of algebra is not explicitly introduced at this stage however a good grounding which prepares them for tackling linear equations.
Progressing into key stage 2 (ages 7-11) brings new challenges to the student. Their breadth of knowledge of numbers and its applications increase substantially. Their range of numbers also span to the 100s and 1000s. Real life monetary problems are modelled mathematically to incorporate an aspect of the child`s life outside the classroom. Pupils explore the manipulations of integers, becoming accustomed with symbols such as < (less than), > (greater than) and = (equal), learning to use them correctly. During ks2 pupils use the number system more confidently.( nat cur) hence learning to order numbers both positive and negative Expanding on prior knowledge of the four main operations (+,-, /, x) they are also introduced to brackets and Distributive, associative and commutative laws of addition and multiplication which help them determine the order of operations. Children also consider simple number relationships and formulae, representing in word form then symbols Although these may seem to have no link to linear equations, they equip the pupil with a base knowledge to be able to solve such problems with ease.
Key stage 3 (11-14) introduces an explicit form of linear equations where the national curriculum creates a subsection within its guidelines of what is required to be taught of the subject at this stage. Linear equations are taught as a concise topic at this stage where pupils are introduced to the concept of equations and the use of letter symbols to represent an unknown. Different notations
Key stage 4 ( 14-16) At this stage pupils are academically assessed on all they have learnt so far. Due to differences in a child`s ability the national curriculum has designed a program of study to attend to the needs of each child hence the teaching program is categorised into two tiers: foundation and higher with the higher tier being more challenging. In term of linear equations
Effective teaching of linear equations Linear equations are implicitly introduced into the Maths curriculum in primary teaching. Most primary schools teach pupils three main subjects and use applications such as ICT or investigations to prepare them for secondary education. Because of its implicit nature at the primary stage, it is paramount that pupils have a coherent understanding of the basic concepts of numbers whereas at secondary the subject is explicitly taught and linked to other areas of mathematics. A different teaching style must be adopted at each level of education to ensure effective teaching of the subject area.
Effective teaching of this subject includes the use of games, adopting a cross-curricular approach, use of visuals (graphs),
Linear equations are largely used in graphing due to its linear properties. They are used to represent straight line graphs given a range of unknown values for x. This is further extended into exploring where two lines intercept hence a system of linear equations. Also studied in the curriculum for mathematics are decimals, fractions and patterns and sequences. all these number forms can be used in solving linear equations where the number is a fraction or decimal or a formula is derived to find the next number in a sequence. Apart from links within mathematics, the use of linear equations is also extended to other subject areas taught in schools particulary science balancing chemical equations and also it`s use in the real world
