Competence aims after year 8

  • work with powers and square roots, and explain their approach and results
  • commutative, associative and distributive properties to
    and communicate strategies for written and mental arithmetic

    Explanation of competence aims

    Concept explanation: Commutativity in addition means that the order of the numbers does not change the sum, meaning that 2 + 3 = 3 + 2. Associativity means that the way you group numbers in addition does not change the result, meaning that (2 + 3) + 4 = 2 + (3 + 4). Commutativity in multiplication means that the order of the numbers does not change the product, meaning that 2 x 3 = 3 x 2. Associativity means that the way you group numbers in multiplication does not change the result, meaning that 2 x (3 x 4) = (2 x 3) x 4. Distributivity shows a relationship between multiplication and addition, for example 2 x (3 + 4) = 2 x 3 + 2 x 4.

  • and
    factorisation and prime factorisation, and to
    this in fractional arithmetic
  • and generalise geometric patterns and numerical patterns in their own words and algebraically

    Explanation of competence aims

    Didactic support: Working with patterns involves pupils describing relationships in geometric and numerical patterns, both in their own words, using drawings, and with algebraic symbols. Generalisation can be done recursively by explaining how the pattern develops from one step to the next, and explicitly, by formulating a direct rule that applies to a specific step or link in the pattern.

  • create and explain mathematical expressions with numbers, variables and constants related to practical situations
  • create and solve equations related to practical situations and critically
    solutions

    Explanation of competence aims

    Didactic support: Work can involve formulating and solving equations as mathematical models for practical situations, where the equations show how the quantities in the given situation are related. The situations themselves can be drawn from example in everyday life, wider society, and real datasets. Critical assessment involves checking solutions upon insertion and assessing whether the results are reasonable in light of the context and assumptions in the model. This work emphasises reasoning, argumentation, and the comparison of different solution methods.

  • different strategies to solve inequalities and
    whether those solutions are valid

    Explanation of competence aims

    Didactic support: Working with inequalities is about finding a set of values that fulfils a comparison between expressions, such as greater than or less than. Find a solution involves the use of systematic strategies to determine which values belong, and this is often supported by a number line and testing of values. Assessing whether or not solutions are valid entails an examination and justification of whether certain values fulfil the inequality, and why others do not.

  • ,
    and
    functions related to practical situations

    Explanation of competence aims

    Didactic support: Working with functions involves exploring the relationship between quantities when the value of one quantity is conditional upon the value of another. A key understanding is that a function describes a rule that links each value of one variable to a specific value of the other. Exploration should be based on practical and visual activities in which these relationships are examined through situations drawn from daily life. The use of function machines, tables, coordinate systems and digital tools affords pupils the opportunity to identify patterns and changes, and to explore what varies and what stays the same. Functions are thus worked with as structured relationships rather than merely as graphs or mathematical expressions.

  • situations, tables, graphs and expressions to represent functions and show relationships between the representations

    Explanation of competence aims

    Didactic support: Working with representations of functions can entail showing that the same mathematical relationship can be expressed in different ways, including through practical situations, tables, graphs, and algebraic expressions. By working with transitions between these representations, it is possible to see what they have in common and what remains unchanged in the context – even if the form of presentation varies. Being able to justify what is the most appropriate representation in a given situation is an important part of the work.

  • how algorithms can be created, tested and improved using programming
