A Nine-Year Old Likes Model Method

I am 9 years old and I live and go to school in Jakarta. I like solving maths word problem by the model method. I go to school that teach maths in the Indonesian language. My mother bought me some Singapore maths book two months ago. I like the model methods that are given in the books. My teacher has never taught maths using the model method. My English is not so good so I must look up a dictionary for difficult words. Can I ask you for help if I find some word ptoblems difficult?

If Jane pose some questions that she finds difficult, I will share it here. But here is one that comes from a school in Singapore. Try it!
88 children took part in a swimming competition. 1/3 of the boys and 3/7 of the girls wore swimming goggles. Altogether 34 children wore swimming goggles. How many girls wore swimming goggles on that day?

  1. No of boys wear glasses = 1u
    No of boys did not wear glasses= 2u
    Total number of boys = 3u

    No of girl wear glasses = 3p
    No of girls did not wear glasses= 4p
    Total number of girls = 7p


    2p= 102-88=14
