Scientific notation is can be very confusing to students. They confuse the positive and negative exponents and when to use them. I have found that by teaching the students to find the old decimal point, label where the new one should go, and count from new to old, it forces them to move in the positive or negative direction, making the sign of the exponent much easier for them to figure out!
