My solution for "The Dishes Problem" is as below:
1. The least common multiple of 2, 3, and 4 is 12. I will calculate how many dishes are used for 12 people.
2. There are 13 dishes needed (6 rice dishes, 4 broth dishes and 3 meat dishes) for 12 people.
3. There are five 13s in 65, so 12 times 5, there are totally 60 people enjoy the meal.
Examples, puzzles and histories of mathematics from diverse culture will make Mathematics engaging and fun. Students could learn mathematics and different cultures at the same time. Moreover, they can learn multiple ways to solve the similar problems.
When I read the book " One Two Three Infinity…." (George Gamow, 1988) I am fascinated by the stories introduced inside. The hand-drawings, photos, characters and plots attract us to read them (please see the figure above ). There is another classic story from Sun Zi Suan Jing which is called " Chicken and rabbits in a cage". It is very interesting. I found almost all kids like to try to solve it. They draw the graphs and learn the principles, and they enjoy it very much. I believe our students will like these puzzles and examples and benefit from them.
Very nice!
