Recommended Letter Introduction Order

It is better to teach letters/phonics not in ABC order, because some letters are harder to learn.

Here is the order I started teaching the 40 letters/phonics in (thanks Mrs. Danielson):

I T P N S A L D F H
G NG O K C CK M R OO B
TH EE Y J Y EE O ER UR IR
SH A I O UR Q V W X Z
