what I would do is first go for the most important, or used elements, starting with H which would be 1.00. They all go in an order. so work on your left side first, the first two rows with your H, Li, Na, K, Rb,Ca, and Fr.second row your Alkaline earth metals Be, Mg, ca,Sr,Ba,Ra. then head over to your transition metals...B, Al
and so from the B To the right side doing the metalloids and halogens which is your far right side of He, Ne,Ar,Kr,Xe,and radon Rn. if she works on those. two rows left side and then the last eight on right side, the numbers go in order, so it is not to hard to remember. just make blank charts and have her fill them in.
