LESSON STRUCTURE CLASS OPENING
Greeting
1)Greet the class.
Say: Good morning/afternoon, class. How are you today How's the weather today
Ask four or five students to respond.
2)Introduce the new unit. Explain the two meanings for the word "plant".
Teacher: Today we will start a new unit. Who can tell me the title of Unit 2
Student: I can. It's "Plant a Plant!"
Teacher: Very good. The word plant has two meanings.
It can be used as a verb and a noun. As a verb, to plant something (like a tree or a flower)means you put it in the ground so it can grow. You can also call this "gardening". As a noun, a plant refers to any living thing that needs water and sunlight to grow. For example, a flower is a plant. Can you give more examples of plants
Write the students' answers on the board or ask them to come to the board one by one to write or draw their own answers.

STEP 1: Present
CLASS WORK: Think About It
1) Explain briefly why trees and forests are important.
Teacher: Trees provide us with so many things. They give us oxygen, shelter and food. Oxygen is the air we breathe. Shelter includes things like the wood that we use to build houses and the shade that the leaves provide. And of course the different fruits that we eat grow on trees like apples, oranges, bananas and so on. Do you know what a big group of trees is called in English It's called a forest. Forests are very important, but they are slowly disappearing. Can you guess why
Students: Because people cut down trees to use their wood and don't plant enough trees to replace the ones they have cut down.
Teacher: That's right. How can we help save our forests
Students: Plant more trees!
2) Ask one student to read the Think About It questions aloud and discuss them as a class.

CLASS WORK: Tic-Tac-Toe
Play Tic-Tac-Toe to review and practice vocabulary, phrases and expressions learned in today's lesson. 1)Draw a large, simple grid on the blackboard. The grid should have three columns and three rows, creating nine squares of approximately equal size. 2)Split the class into two teams. Ask a player on Team I a question. If the player or team answers correctly, a player from that team may write an X in any square on the grid.
3) Team 2 now has a turn. If the team answers correctly, a player from that team may write an O in any square on the grid.
3)Team 2 now has a turn. If the team answers correctly, a player from that team may write an O in any square on the grid.
4)The object for each team is to obtain a row of three X's (or three O's) in any direction: horizontal, vertical or diagonal. Of course, teams also want to place their X's or O's to block the other team from completing a row. The first team to obtain a row wins one point and the game continues.
