Looking ahead
The thesis of CGI is that Children enter school with a great deal of informal or intuitive knowledge of mathematics that can serve as the basis for developing understanding of the mathematics of the primary school curriculum without formal or direct instruction on specific number facts, algorithms or procedures, children can construct viable solutions to a variety of problems. Basic operations of addition, subtraction, multiplication, and division can be defined in term of these intuitive problem-solving processes, and symbolic procedures can be developed as extensions of them.
