It is very important to build a solid foundation for math. After we tried different math books to homeschool our children, we like Saxon Math best and Saxon Math is indeed very popular among homeschooling families. They use "incremental" approach, i.e. introduce concepts in small pieces and then continually review that concept as they add more pieces. Topics are never dropped; instead, they are gradually increased in complexity, allowing it to become second nature. Just a small investment but give your children a strong start in Math. It is a very worthy investment.
