Time required to use the resource with the students depends on the aim of the lesson. The video lasts 8:52. How to use it: The video should be demonstrated after introducing the topic. It should be stopped every time key words appear on the screen. Teacher should make sure that the students understand not only the key words but the other words that appear on the screen as well. The video should also be stopped once examples of converting percent into fractions or converting percent into its decimal value is presented for students to have time to complete similar tasks individually and to compare the results working in pairs. After watching the video, students are asked if they remember, what real life examples of using percentages were given in the video. They are also invited to work in pairs and to think of more examples where percentages could be used. Students share their ideas with their classmates, the teacher comments students’ ideas and gives more examples to prove that percentages are important for understanding the financial aspects of everyday life. Possible difficulties for the students: students whose knowledge of English is poor can face difficulties as the presenter speaks very fast.
