Welcome the students to the lesson. Use this slide to introduce the theme 'Tree-mendous Adventures'. Emphasize that today they will learn all about trees through pictures, stories, and a fun outdoor activity.

Discuss what a tree is. Ask the students simple questions such as 'What do you see in a tree?' or 'Have you ever seen a big tree outside?' Use simple language and visuals if available.

Use visual aids like pictures or cards to introduce the parts of the tree. Explain that a tree has a trunk, branches, and leaves. Use simple words and encourage students to point out these parts on the picture.

Share fun facts about trees in an engaging way. For example, mention how trees help clean the air, provide homes for animals, and can live for many years. Ask the students if they can think of any animals that live in trees.

Prepare the students for the mini nature walk. Explain that they will go outside to see real trees and compare them to the pictures they've seen. Remind them to stay close and listen carefully.
