Why is alphabetizing important?
Alphabetizing is an important skill to master. It helps develop organizational skills, executive functioning abilities and it even improves memory. Furthermore, if we sequence materials that we are encoding into our brains, it makes it easier to access at a later date.

Is the letter Z symmetrical?
The letter Z is an example of “2-fold Rotational Symmetry”; it looks the same after being rotated by 180° around its center. But it does not have mirror symmetry. Shapes like this are called “chiral”, which means that they can not be superimposed on their mirror images.
