Vocabulary - Pattern and Symmetry

The vocabulary terms 'pattern' and 'symmetry' are key concepts in the study of mathematics and art, especially relevant to Key Stage 2 students. A 'pattern' refers to a design or sequence that is repeated, which can be found in nature, architecture, and various forms of artwork. The beauty of patterns often lies in their consistency and predictability, with a 'repeating pattern' being a sequence that is replicated over and over again. 'Symmetry', on the other hand, describes the balanced and proportionate similarity found in two halves of an object or design. When something is 'symmetrical', it means that one half is a mirror image of the other, often divided by a 'line of symmetry'.

In discussing symmetry and patterns, size plays an important role. Terms such as 'bigger', 'larger', and 'smaller' help describe the relative dimensions of objects or parts of a pattern. A 'fold' in a piece of paper can demonstrate symmetry when both halves 'match' perfectly. Similarly, a 'mirror line' is an imaginary line that acts as a reflection point, creating two symmetrical halves. This concept is further explored with a 'mirror', which shows the 'reflection' of an object. To 'reflect' is to cast back an image or shape, mirroring the original. These fundamental terms provide a foundation for understanding the principles of pattern and symmetry, concepts that are visually and intellectually stimulating for learners.
