Periodic Table

To help XP understand chemistry better,
I made this Periodic Table for her, it can be folded and opened up.
Everytime she learns something new, she has to write it down,
the blue colour here means the elements in this column have the similar characteristic .

.

.......this is the normal one.......

.

.

.........this is the fully open up one.........

.

.

......... and this is the all folded up one..........

so that we can count the electrons (outest shell) easily.
