Adding and Subtracting Fractions - PowerPoint

In this educational resource designed for Year 3 students, the focus is on understanding and practising the addition and subtraction of fractions with the same denominator. The lesson begins by defining fractions as equal parts of a whole, which can represent parts of an object, quantity, or number. Students recap the structure of fractions, identifying the numerator and denominator in a fraction written as a numeral. The numerator indicates the number of equal parts being considered, while the denominator shows into how many parts the whole is divided.

The lesson then moves on to explain the straightforward process of adding fractions with the same denominator, where only the numerators are added while the denominator remains unchanged. This concept is visualised through diagrams that help students see the fractions being combined. Similarly, subtracting fractions is taught by subtracting the numerators and keeping the denominator constant. Students are encouraged to practise these operations through various exercises and word problems provided in worksheets. These activities aim to reinforce their understanding and application of adding and subtracting fractions in different contexts.
