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.
English Worksheets _ What you can do to make working on printable worksheets more enjoyable for your child may often depend on the age and interests of the child. For example, older children may have to read a poem which is on the sheet and then write their own poem in the same sort of style. If they have been used to playing word games while growing up this shouldn't be a problem, you just have to find a way of making the doing of it attractive. One thing that they might enjoy is if you put on a favourite cd and get them to see if they can use some of the main phrases from that in a different way, i.e. in the style of the poem. Depending on your child's age and concentration span there are plenty of fun ways to get them working on printable worksheets.
