Halves, Quarters and Three Quarters as Decimals - PowerPoint

This educational resource is designed for Year 4 students to explore the concept of fractions and their decimal equivalents, specifically focusing on halves, quarters, and three quarters. The material utilises a visual approach by asking students to colour portions of a grid to represent these fractions. For instance, when half of the grid is coloured, it illustrates that 5 out of 10 parts are filled in, which is equivalent to the fraction 1/2 and the decimal 0.5. Similarly, colouring a quarter of the grid shows that 25 out of 100 parts are filled, equating to the fraction 1/4 and the decimal 0.25. The exercises progress to three quarters, where colouring 75 out of 100 parts demonstrates the fraction 3/4 and the decimal 0.75.

The resource continues to reinforce understanding through practical application. Students are prompted to colour shapes with the decimals 0.5, 0.25, and 0.75, and then compare their results to example answers, encouraging them to recognise that these decimals represent the same proportions as the fractions half, quarter, and three quarters. Additionally, students are challenged to identify the shaded portions of various shapes and express these as decimals. To deepen their comprehension, a worksheet is provided where students write the decimal equivalents of given fractions, including more complex ones such as 4/8, 9/12, and 8/32, guiding them through the process of converting fractions to decimals in a clear and interactive manner.
