People have to start from the ground, then first step, second, third and so on to reach their destination floor. Exactly the same way students have to start from Kindergarten, then grade one, grade two and three and so on to reach their math destination. Also, if some of the steps are broken in the staircase, it is still hard to reach the desired floor using those steps. Same way, if you are missing some of the basic concepts from elementary grades, math for you is still hard. Now, the kindergarten, first grade and second grade are like first couple of the steps of the stairs. You can learn this level of math easily, as you can jump enough to take yourself to second or third step of the stairs easily. As it is very hard to reach sixth or seventh step of a stairs by jumping from the ground, exactly the same way to learn grade five or higher grade math is very hard (or impossible) without having the good knowledge of the kindergarten to grade three or grade four math. Now, consider one person is jumping on the ground to reach the third floor of a building. Can this person make it? Never, if he is not Spiderman. For this person, to reach the third floor by jumping is impossible or very hard and finally he gave up saying that it was very hard to reach third floor.
Which brings us to the purpose behind this article. One of the most effective ways I've found to help kids in a focused area of weakness are printable math worksheets. The big problem with concept_based instruction is lack of practice. Printable math worksheets solve this problem nicely. As a teacher, I supplement my lessons with appropriate worksheets. I can then check a student's progress. I can also monitor how much work they actually are doing. For parents, printable math worksheets are a great tool for drilling their own kids in those same skills. Make no mistake, printable math worksheets are not a relic from the past that needs to stay buried. They are useful, focused tools for the classroom or at home. You can find resources all over the web for worksheets. Finding answers for worksheets, however, is not that easy. For that you often have to use paid subscription services.
