I am a teacher of gifted program in primary school and currently I am developing Olympiad Curriculum (topic-wise) for my students. I have those topics that could need some help in terms of questions:
- Number theory: common multiples, unit digit, divisibility and remainder
- Combinatorics: counting figures
- Geometry: area of polygons and circles
- Logical thinking: logical puzzles
- Arithmetic: solve complex arithmetical problems, number puzzles..
Can anyone suggest good books/e-books for me to add in question banks? Thank you!
