NEVER use "skill and drill" worksheets. These are the worksheets just made up of columns of problems. There are better materials out there, so do not resort to skill and drill. The very worst problem of skill and drill worksheets is the greatly increased chance of a practiced mistake. The same problem will likely appear several times on the same sheet. A wrong answer once means a wrong answer several times; and a practiced mistake takes hundreds of correct repetitions to fix. This danger alone is important enough to never use any worksheet. I am quite serious about how difficult it is to repair a practiced mistake. Learning is hard enough. Re-learning is much more difficult.
Most of even beginning algebra depends on being able to do two things--one, doing multiplication quickly and accurately in your head, two, knowing how to add, subtract, multiply, and divide fractions. You might remember a concept in algebra called factoring. Factoring means breaking up into parts that are multiplied together to give you the whole. You can factor numbers. For instance, 6 factors into 2 and 3--2x3 =6. In elementary algebra we learn to factor expressions such as x^2+4x+4. This particular expression is easily factor-able into (x+2)^2. If this does not make any sense to you, do not worry about it. Just trust me, if you do not know your multiplication tables, you can not factor. If you can not factor, you will not do well at all in algebra, geometry, or trigonometry.
