i said text-guided lesson plan!
I apologize for the confusion. Here is the text-guided lesson plan for teaching zero and first conditional to pre-intermediate ESL students.
Text:
If you want to stay healthy, you should eat a balanced diet and exercise regularly. If you eat too much junk food and don't exercise, you may gain weight and become unfit.
Objectives:
By the end of the lesson, students will be able to:

• 
  Understand the difference between the zero and first conditional.
  
• 
  Use the zero and first conditional to talk about real and hypothetical situations.
  
• 
  Construct their own zero and first conditional sentences.
  

Procedure:

1. 
   Pre-Reading Discussion (5-10 minutes):
   

Start the lesson by asking your students if they know what a conditional sentence is. Encourage them to give some examples. Write their ideas on the board and discuss the different types with the class.

2. 
   Reading and Vocabulary (10-15 minutes):
   

Introduce the text by telling the students that it is about health and staying fit. Ask them to read the text silently and underline any words they don't understand. Then, elicit the words from the students and write them on the board.

3. 
   Grammar Focus (15-20 minutes):
   

Explain the zero and first conditional in more detail. Use the following structure for each conditional:

• 
  Zero Conditional: if/when + present simple, present simple.
  
• 
  First Conditional: if/when + present simple, will/won't + infinitive.
  

Write some examples on the board to illustrate the difference between the two conditionals:

• 
  Zero Conditional: If it rains, the streets get wet.
  
• 
  First Conditional: If it rains tomorrow, I will stay at home.
