Square Numbers - PowerPoint

Square numbers are an essential concept in Year 5 maths, focusing on multiplication and division. These numbers are the result of multiplying a number by itself. For instance, 1 multiplied by 1 equals 1, and 3 multiplied by 3 equals 9. This concept is visually represented by creating square shapes with dots or counters, hence the name "square numbers". The educational material explains that square numbers can be easily identified by their ability to form perfect squares, and it provides clear examples, such as 2 x 2 equalling 4, which can be arranged in a 2x2 grid of dots.

The resources further delve into how to express square numbers using mathematical notation, where a small '2' is placed at the top right of the base number to denote squaring, such as 5 squared being written as 5². Students are encouraged to identify square numbers from arrays and to solve problems that involve finding or proving square numbers. The learning objective is to recognise and use square numbers through various activities, including filling in missing numbers in arrays, circling square numbers from a list, matching equivalent amounts, and completing number sentences by solving for missing numbers. The material includes both worksheets and answers, enabling students to practice fluency, reasoning, and problem-solving skills related to square numbers.
