Unit 4 Section A Grammar Focus-3a-3d 教学设计 2025-2026学年人教版英语七年级下册

Unit 4 Eat Well Section A: What do we like to eat? Period 3: Grammar Focus – Countable & Uncountable Nouns (3a–3d) Class Type: Grammar & Integrated Skills Duration: 45 minutes Grade: Grade 7 I. Teaching Objectives 1. Language Knowledge Objectives • To distinguish between countable nouns (e.g., an apple, two eggs) and uncountable nouns (e.g., some rice, a little milk) in the context of food and drink. • To apply the correct determiners and quantifiers with nouns: ◦ a/an, numbers, many with countable nouns. ◦ some, any, much, (containers like a glass of) with uncountable nouns. • To recognize a few common nouns that can be both countable and uncountable with a change in meaning (e.g., chicken, fish). 2. Language Skill Objectives • Grammar Application: To complete sentences, conversations, and a short passage by correctly selecting or forming nouns based on their countability. • Integrated Speaking: To create and perform a simple, context-driven dialogue that naturally incorporates both types of nouns. 3. Emotional & Attitudinal Objectives • To demystify a common grammar challenge by providing clear, practical rules and ample practice. • To appreciate how accurate grammar improves clarity in everyday situations like offering food. II. Key & Difficult Points • Key Points: 1. The core distinction: Countable nouns refer to items you can count individually; uncountable nouns refer to substances or concepts treated as a whole. 2. Using the correct “partner words” (a/an vs. some) with each noun type. • Difficult Points: 1. Internalizing the Concept: Overcoming the influence of Chinese, where the countability distinction is less strict. 2. Handling “Dual-Use” Nouns: Understanding that words like chicken can mean the animal (countable) or the meat (uncountable). III. Teaching Preparation 1. Teacher: • PPT with: contrasting visuals (e.g., three apples vs. some rice), clear graphic organizers for rules, animated highlighting for noun endings (-s, -es), and all exercise instructions. • A set of realia or very clear flashcards for key “problem” nouns (an egg, some milk, a chicken (toy), some chicken (picture of meat), a fish (toy), some fish (on a plate)). 2. Students: • Worksheet 1: Discovery chart for the Grammar Focus box and exercises 3a-3c. • Worksheet 2: “Hosting a Friend” dialogue scaffold for 3d. IV. Teaching Procedures Step 1: Warm-up – The Sorting Challenge (5 minutes) 1. Concept Activation: • Hold up realia/flashcards of an apple and some rice. T: How many apples? (One apple). How many rice? (…We don’t say that. We say some rice or a bowl of rice). So, ‘apple’ and ‘rice’ are different types of words in English. 2. Introduce the Mission: T: Today, we become ‘Word Detectives’ to learn the rule behind this difference. It will make your English much clearer! Step 2: Discovery & Rule Formation (3a – 10 minutes) 1. Inductive Discovery: • Direct students to the Grammar Focus box. On Worksheet 1, they work in pairs to: 1. Find all the food/drink words. 2. Sort them into two lists: List A: Words you can put ‘a/an’ or a number in front of (e.g., an egg, two strawberries). List B: Words you CAN’T use ‘a/an’ or a number with, but use ‘some’ (e.g., some meat, some milk). 2. Elicit and Name the Rules: • Elicit students’ lists and write them on the board in two columns. • Introduce the terms: Countable Nouns (List A) and Uncountable Nouns (List B). • Co-create simple rules: Countable nouns can be one (a) or more (-s). Uncountable nouns are for things we don’t count one, two, three... we use ‘some’ or ‘a cup/bowl of’. 3. Controlled Identification: • Students complete the textbook activity 3a, circling nouns and labeling them C or UC to apply their new understanding. Step 3: Guided Practice in Context (3b & 3c – 12 minutes) 1. Practice 1: Completing Conversations (3b – 6 mins): • Students work on 3b individually, filling in blanks with the correct noun form. • Peer Check & Justification: In pairs, students compare answers and must explain why they chose that form (e.g., “Number 1 is ‘fish’ because it’s the food, not the animal, so it’s uncountable here.”). • Class Feedback: Confirm answers. Use the realia to visually demonstrate the fish (animal) vs. fish (food) distinction. 2. Practice 2: Completing a Passage (3c – 6 mins): • Students complete the short passage in 3c on Worksheet 1. • Class Check: Read the passage together. Ask comprehension questions: “Does the person eat healthy food? Find the evidence.” Step 4: Creative Production – The Hosting Dialogue (3d – 15 minutes) 1. Task Setup – “You have a visitor”: T: Now, use your grammar skills in a real situation. Your friend is visiting your home. You want to offer them food and drink. Prepare a short conversation with your partner. 2. Scaffolded Creation: • Distribute Worksheet 2, which provides: · A simple scenario. · A box of required elements: Use 2 countable nouns (with a/an or numbers). Use 2 uncountable nouns (with some). Use “Would you like…?” · A dialogue frame with blanks. • Pairs create their dialogue. Teacher circulates, prompting: “Is that noun countable? What should you put before it?” 3. Rehearsal and Performance: • Pairs practice their dialogues, focusing on clear pronunciation. • Invite 3-4 pairs to perform. After each, ask the class: “What countable/uncountable nouns did you hear?” Step 5: Summary & Homework (3 minutes) • Summary: T: Excellent detective work today! Remember the big idea: Can you count it? If YES → it’s countable (a/an, -s). If NO → it’s uncountable (some). This rule is a key to speaking English correctly. • Homework: 1. Rule Consolidation: Complete the “Grammar Summary” section on Worksheet 1, filling in examples for countable and uncountable nouns. 2. Real-World Hunt: Look in your kitchen. Write down 3 countable and 3 uncountable food/drink items you find there. V. Assessment • Formative (Observation & Product): Teacher assesses the discovery process on Worksheet 1 and monitors accuracy during pair work for 3b and 3d. • Product-based: The completed Worksheet 1 and the in-performance dialogues serve as key evidence of understanding. VI. Blackboard Design ``` Unit 4 Grammar Focus: Countable vs. Uncountable Nouns | Countable Nouns (C) | Uncountable Nouns (UC) | |--------------------------|--------------------------| | You can COUNT them. | You CAN'T COUNT them. | | one apple, two apples | some rice, some milk | | a/an egg, three carrots | a bowl of rice | | Use: a/an, numbers, many | Use: some, any, much, | | | a cup/bowl/glass of | Examples from Today: C: egg, strawberry, noodle, vegetable UC: bread, meat, milk, rice, sugar BOTH: chicken, fish, cake, salad ``` VII. Teaching Reflection (Post-Lesson) • Discovery Effectiveness: Were students able to deduce the core countability rule from the examples, or was it too abstract? What percentage of the class could accurately complete the initial sort? • Practice to Production Bridge: Did exercises 3b and 3c adequately prepare students for the linguistic demands of creating their own dialogue in 3d? Where did the gap become apparent? • Handling “Dual-Use” Nouns: Was the brief, visual explanation of chicken/fish sufficient, or did it cause confusion? Should this be deepened or postponed? • Task Engagement: Did the “hosting a friend” scenario feel authentic and motivating for practicing the grammar? How was the partner collaboration? • Common Error Pattern: What was the most frequent error (e.g., adding ‘s’ to uncountable nouns, omitting ‘a/an’) that needs targeted review in the next lesson? 学科网（北京）股份有限公司 $
