  Rule 1:  Words ending with a Consonant-Vowel-Consonant  Pattern                      
                                       (Review Consonants and Vowels)
One-syllable words:
ED =  If the word ends in a CVC pattern, it gets a double consonant + ED.     * note
ING =  If the word ends in a CVC pattern, it gets a double consonant + ING. * note

Examples:

ED =   RUB > rubbed, STOP > stopped

ING = HOP > hopping,  SIT > sitting

*note: Words ending in w,x,y,z do not follow this rule, simply add ED, or ING Examples: snow > snowed, box > boxing, play > playing

Two-syllable words:
ED =  If the stress is on the first syllable, the word only gets one consonant + ED.
ING = If the stress is on the first syllable, the word only gets one consonant + ING.

Examples:

visit > visited, open > opened

happen > happening,  enter > entering

ED =  If the stress is on the second syllable, the word gets a double consonant + ED.
ING = If the stress is on the second syllable, the word gets a double consonant  + ING.

Examples:

refer > referred,     admit > admitted

begin > beginning, permit > permitting

Consonants = b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z Vowels = a, e, i, o, u

   Rule 2: Words ending in E                                                                        
ED =  If the word ends in E, simply add D
ING =  If the word ends in E, drop the E, add ING

Examples:

ED =   smile > smiled, fine > fined

ING = dance > dancing, skate > skating

   Rule 3:  Words ending in Y                                                                                  

Consonant + Y
ED =  If the word ends in Y, and has a consonant before it, change the Y to I and add ED.
ING =  If the word ends in Y, and has a consonant before it, simply add ING.

Examples:

ED =   study > studied, marry > married

ING = carry > carrying, reply > replying

Vowel + Y ED =  If the word ends in Y, and has a vowel before it, simply add ED.
ING =  If the word ends in Y, and has a vowel before it, simply add ING.

Examples:

ED =   play > played, stay > stayed

ING = enjoy > enjoying, stray > straying

   Rule 4:  Other words...                                                                                         
words ending in two vowels + a consonant
ED =  If the word ends in two vowels + a consonant, simply add ED.
ING =  If the word ends in two vowels + a consonant, simply add ING.
 

Examples:

ED =   dream > dreamed, rain > rained

ING = need > needing, beep > beeping

words ending in a double consonant:
ED =  If the word ends in a double consonant, simply add ED.
ING =  If the word ends in a double consonant, simply add ING.

Examples:

ED =   park > parked, earn > earned

ING = need > needing, laugh > laughing
