![]() This activity explores time-series data and shows how calculating and plotting moving averages can help to iron out fluctuations and spot trends. Without technology, students then have to predict these key points for different functions. Students record the key, defining points in a pre-prepared table: coordinates of the maximum and minimum and x-intercepts, as they change different parameters using the constant controller or sliders. Age: 15+ Time: 1hĪge: 15+ Time 1-2 hrs Using Autograph or the free Geogebra or Microsoft Maths 4.0, students investigate the functions of the sine and cosine graph. This challenge provides a great incentive to explore, experiment and share ideas. However, the questions are disguised in videos of moving graphs that students are asked to reproduce. y=f(x-a), y=f(ax) for the quadratic function. The aim is to explore the basic transformations of a function, e.g. This immediately absorbing and engaging activity requires students to use graphing software.
