But another person used the stairs to reach the same floor. This person found it very easy and reach there with little effort. Compare this person to a student who knows all the basic concepts learned in elementary grades. To learn grade six or grade seven math for this student will be easy. But there is another student in grade six and doesn't know the lower grade math concepts such as, times tables, factors or number system. This student is in the same situation as the person, who is jumping to reach third floor from the ground level. From the example it is very clear that mathematics in each grade have the same importance. So, you need to be focused on math in all the grades on all the basic concepts. Ask your teachers lots of questions. Keep asking until you are not clear about the concepts or topics you are working on.
I teach the upper grades in my school, yet I continue to see kids who do not even have basic algebra skills in place. As a parent, I'm very aware of what my own children are learning in school. For the most part, I've been happy with their progress, but as they rise in grade level, I'm starting to see more emphasis on a loose understanding of the concepts and less emphasis on skills__particularly skills with arithmetic of fractions. The main problem with what I see with my students and my own children is that kids are taught "concepts" and are not taught skills__unless they're lucky enough to have a teacher who knows better. Most particularly, children are not taught mastery of arithmetic with fractions. Unfortunately, virtually all of their future math education depends on being able to do fractional arithmetic.
