A visitor centre has tracked it’s international visitors, and compared the country of origin of current visitors to the country of origin back in 1992. The daily visitors and their countries of origin are shown in these two pie charts:
Louise has stated that “there are now twice as many UK visitors as there were in 1992”.
a) Prove using Maths, that Louise’s statement is incorrect.
b) Use Mathematical language and calculations to create three factual statements based on the information shown above.
This is a new style of GCSE question where students are asked either to prove something, and draw conclusions or statements which are validated with Mathematics. Students benefit from practising answering with calculations, and not just words, although drawing three conclusions normally takes a good 5 or 6 minutes. As a teacher, you can choose the level of validation that you find acceptable – whether words only or full workings. There are obviously many correct answers to question b.
Teachers could extend the learning by considering:
- What other graph could display this information, maybe even clearer?
