Pig-latin is a form of transposition cipher where the original letters are kept intact (albeit with the addition of the suffix "ay"), but rearranged in some way. Going back way before your school days, to the 5th century B.C., the Spartans used an interesting transposition cipher called a scytale. The scytale utilized a cylinder with a ribbon ... Another type of cipher, the Patristocrat, uses the same method of encryption but normal word divisions are not retained. An additional "rule" used by the ACA is that no plaintext letter can be substituted by the same ciphertext letter so the keyed alphabets can be shifted to avoid this.

The atbash cipher is a simple substitution cipher from Biblical times; it reverses the alphabet such that each letter is mapped to the letter in the same position in the reverse of the alphabet (A -> Z, B -> Y). The original implementation (ca. 500 BC) was for the Hebrew alphabet and there are Old Testament references to it.

The Vigenère cipher is a polyalphabetic substitution cipher that was invented by Giovan Battista Bellaso in 1553.
