Number Theory

This is a one-semester course.

Numbers are an interesting topic in and of themselves, and it is important for children to develop number sense that will help them in many aspects of their life, whether they’re going to do advanced mathematics or simply balance a checkbook. With an emphasis on practical applications, this course offers a range of problems to make it easy for children to understand the implications of number theory.

This course will offer a problem-solving approach to topics in number theory, including primes and composites, multiples and divisors, prime factorization and its uses, base numbers, modular arithmetic, divisibility rules, and linear congruences.

This course is set for the appropriate level of difficulty for children in the seventh or eighth grade.
