Project Euler
An online resource that provides hundreds of challenging mathematical problems, this website promotes self-directed learning by offering pre-designed problems with content and vocabulary related to advanced mathematics and programming skills. It provides differentiated instruction for high-achieving or gifted students at the senior level and those with high cognitive skills and emotional maturity levels. Students are encouraged to solve complex problems, individually or collaboratively. Problems can be solved using a computer program or algorithm, and this resource may be particularly suitable for those who are comfortable with text-based programming and have an advanced understanding of mathematical concepts.
