Time required to use the resource with the students depends on the aim of the lesson. It could be used for one or two lessons (45 – 90 min).
How to use it:
The teacher distributes copies of the worksheets to the students. Working individually, students revise the topic of percentages and get ready to answer the questions: What is a percentage? What is the formula for calculating percentages? After revising the theory, analysing examples of percentage calculations and analysing a common error when finding a percentage, students get other worksheets and work on percentage calculations individually.
To understand the calculations better, similar types of problems to those in the examples are solved in a series of three mini-lessons on Calculating with Percent.
Possible difficulties for the students: students whose knowledge of English is poor can face difficulties understanding the text.
