Use nouns before uncountable nouns to show their amounts. IV. Teaching procedures Step 1 Lead-in 1. Odd One Out. Play a game called “Odd One Out”. Let Students choose one picture which is different from the other three. They should tell the reasons. (1) apple pear lemon bread Reason 1: Apple, pear and lemon are fruits. Bread is not fruit. Reason 2: Apple, pear and lemon are countable nouns. A countable noun refers to something that we can count. For example, an apple, two pears and ten lemons. But bread is an uncountable noun. An uncountable noun refers to something we cannot count. For example, we cannot say a bread. Explain Reason 2 slowly to make students understand what a countable noun and an uncountable noun are. (2) milk juice cola carrot Reason 1: Milk, juice and cola are drinks. Carrot is a kind of vegetable. Reason 2: Milk, juice and cola are uncountable nouns. Carrot is a countable noun. (3) photo potato tomato mango Reason 1: Potato, tomato and mango are something that we can eat. But we can’t eat photo. Reason 2: We should add “es” to potato, tomato and mango to form their plural forms. But we just add “s” to photo to form its plural form. (4) man policewoman child toy Reason 1: Man, policewoman and child refer to people. Reason 2: The plural forms of man, policewoman and child are irregular. The plural form of toy is regular, just plus “s”. Step 2 Presentation 1. “A” or “an”. T: Do you know when to use “a” and when to use “an”? If the countable noun begins with a vowel sound, we use “an”. If the countable noun begins with a consonant sound, we use “a”. 2. The plural of countable nouns. T: Do you know how to form the plural of countable nouns? (1) an orange → two oranges; a cake → two cakes Rule 1: We add “s” to most nouns. (2) a story → some stories Rule 2: If the noun ends in a consonant + y, we should change “y” into “ies”. (3) a bus → two buses; a brush → three brushes; a match → some matches; a box → four boxes Rule 3: We should add “es” after the nouns ending in “s”, “sh”, “ch” or “x”. (4) a photo → two photos; a potato → three potatoes; a tomato → some tomatoes Rule 4: We should add “s” or “es” after the nouns ending in “o”. (5) a knife → two knives; a scarf → three scarves Rule 5: We should change “f”/“fe” into “ves” if the noun ends in “f” or “fe”.
