Re: is learning fractions hurting children?

Dan,
I agree 100%. For example factoring, for reducting fractions. The student who does not know the division facts at the 100% level, ie (21)/(3) = (7), will have a great deal of trouble reducing the fraction (14)/(21). In my work with high school students, I find a large number who do not know the multiplication and division facts (012).
People who don't want to teach fractions, don't understand where fractions fix in the big picture. Look at probability. The smallest probability number is 0 and the largest probability number is 1. All other probabilites are between 0 and 1, ie a fraction or a decimal. If the student is not completely proficient with fractions and decimals then it is a waste of time to study probability, the student can't work any problems.
Most of the math taught in grades k8 has this prerequisite relationship. In the development of AMATH we reverse engineered the prerequisites for Algebra I and developed 97 modules covering k8 math. The program insists that the student master each module.
