Federal enrichment for mathematics is usually limited in involvement. The federal government designs minimum standards and often has grants available for schools to implement the programs. In most cases, the federal grants are given to enrichment programs that are likely to succeed.
The math Olympiads programs are a type of mathematics enrichment schools might employ to help students in primary school. A math Olympiad program is a thought-provoking math program where students must solve complicated and often unusual problems for the age group. It is designed for older students in primary school around fourth grade or higher due to the complexity. It requires math practice and then competition between schools.
Math enrichment is not limited to physical studies of the subject, but can use online technological resources to produce thought-provoking problems and study for students in math. Setting up an online program might require finding websites which provide unusual math problems for the age group or complex problem solving or creating a website if preferred.
After school enrichment programs are another option for mathematics enrichment. These take the idea of the math Olympiads or online website options and put the ideas together. A teacher gives the students problems to solve which are challenging, but suitable to the grade level, and then have the students work out the math problems.
