How can I learn polyatomic ions quickly?

My science teacher is the best for helping us to learn stuff, and she gave us a sheet that had a table on it, it has boxes and in each box are all the ions of a particular valency. Make a table like this, then keep writing it out over and over again, learning one box at a time, then slowly adding them together, ie once you've learned 2 boxes, go over both of them and try to recall every ion, then same with 3 boxes, 4 boxes etc. The other thing we did was get a piece of paper, with lots of rows and columns. In the left column is the name of the ion, in the right column is formula and valency.

In between have as many columns as you need, maybe 10, where you try to write the valencies/formulas without looking. Fold the paper so that the column with the formulas already written in it is covered up, then when youve tried to write them all out, unfold it and mark your answers, keep doing it until you can get them all, then do some more just to make sure you don't forget I'm assuming you ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
