Vocabulary - Problem-solving

The vocabulary set provided is essential for KS2 students delving into the realm of problem-solving and mathematics. It includes terms like 'pattern', which refers to a repeated decorative design or sequence, and 'puzzle', a game or problem that tests a person's ingenuity or knowledge. The action 'calculate' and the noun 'calculation' are at the core of mathematical problem-solving, involving the process of using arithmetic to determine an amount or result. These terms are fundamental for students to understand and apply mathematical concepts effectively.

Additionally, the vocabulary highlights the importance of 'mental calculation', which is the ability to perform arithmetic operations in one's head without the use of calculators or paper. The term 'method' refers to a particular form of procedure for accomplishing or approaching a task, while 'jotting' implies a quick, informal way of writing something down briefly. 'Answer', in this context, is the solution to a problem or question. The set also differentiates between 'right' and 'correct', which indicate accuracy, and 'wrong', which signifies an error, prompting the question 'what could we try next?' to encourage further attempts and learning. 'How did you work it out?' invites students to explain their process, which might involve a 'number sentence' – a mathematical statement that includes numbers, operations, and an equal sign. 'Sign', 'operation', and 'symbol' relate to mathematical notation, while 'equation' represents a statement of equality between two expressions. Lastly, 'idea' and 'conjecture' are terms that encourage students to form hypotheses or predictions based on their understanding and exploration of mathematical concepts.
