Rule #1 If a word ends in a sound that is unvoiced (such as P,T,K,F), you add an unvoiced /S/
Examples:
1 cup,
2 cups
(the ‘p’ in cup is unvoiced, so you just add an unvoiced ‘s’)
1 cat,
2 cats
(the ‘t’ in cat is unvoiced, so just add an unvoiced ‘s’)
I break,
I stop,
he breaks
he stops
Rule #2 If a word ends in any of these sounds: ‘s,z,sh,ch,or dg (j)’ when adding an ‘S’ ending, add… IZZZZZZ
Examples:
|
1 Page 1 Bus 1 Lunch I Raise I Brush I Push |
2 Pages 2 Buses 2 Lunches He Raises He Brushes He Pushes |
Rule #3 If a word ends in a vowel sound (like the word Tree) or a voiced consonant (like the word Game), then when you add an ‘S’, continue the voicing throughout the entire word, and it should become a voiced ZZZZ.
Examples:
|
1 Tree, 1 Day, 1 Shoe, I Fly, 1 Game, 1 Head, 1 Train, 1 Song, |
2 Treezzzz (correctly spelled Trees) 2 Days 2 Shoes He Flies 2 Games 2 Heads 2 Trains 2 Songs |
