Put the Elements in order!
With 4 different levels.
Beginner starts with the first 20 elements. This is ideal for a grade school child to be introduced the Periodic Table and covers elements that they've probably heard of.
Intermediate adds all noble gases, non-metals, alkaline earth metals, alkali metals, post-transitional metals and halogens.
Advanced is all elements, but there are colorings on the background to make it a bit easier.
Expert, the background is all the same color to make it slightly harder.
