B1/B1+

Time required to use the resource with the students:
The teacher can use the resource with the students for one lessons. Video lasts 8:52 minutes.

How to use it
Before using the video during one’s classes, the students should be able to do basic operation with fractions and decimals.
The teacher asks students to watch the video and does pauses in certain moments to give students opportunity to make notes, asks questions and develop some problems presented in the video.
During lessons the teacher should ask the student in English:
“What is the percent?”, “Do you know the symbol of the percent?”
“What does mean 0%?”,“What does mean 100%?”, “How to change fraction into decimal?”, “How to change percent into fraction?”, “What kind of tricks presented in the video do you remember?”, “How to change percent into decimal?”
The students give the answers with the examples. The teacher should give them a feedback and show students more examples on the black table. For example, the teacher can asks students to work in pairs and rewrite 15% as a fraction and a decimals. The teacher highlights some new words for students in English and students should find the translation these words into the mother tongue and write down the new words in English in the notebook with the right translation in their own words. The teacher can asks students to remember words in English like: convert, fraction, improper fraction, decimal.
Students should practice themselves. The teacher provides more exercises, checks the answers and gives feedback.
Possible difficulties for the students
Students who have poor knowledge of English can have problems with understanding the content. Students who has problems doing basic operations with decimals can face difficulties in solving math problems with percentages which are introduced in the video which is recommended.

Comments
The resource provides interesting self-directed learning, it can be used by teachers as a model to help them teach their own students how to convert percentage into fraction or decimal. The strength of the video is a rich content, visuals, clarity of explanation, and a simple sentence structure. It presents an easy way to remember the steps for converting percentage into decimal and uncluttered, understandable strategies which are easy for students to remember and for teachers to teach. What is more, the academic language presented in the video helps to develop academic vocabulary. In my opinion this web site is scientifically reliable and can be recommended to students and teachers, it is intuitive and usable. A layout is focused on ease of use, and ease of watching. The video is funny and attractive for teenagers. Consistent design allows the user to focus on the message. The resource could be more visually appealing to students and provide a wider range of different types of exercises.
