Introduce the lesson by welcoming the students. Explain that today they'll be using their creativity and critical thinking to design apps that solve real-world problems. Emphasize that the session is interactive and project-based.

Discuss what app design means. Mention that apps can range from fun games to solutions for problems like managing homework, staying organized, or connecting with friends. Use examples students might relate to.

Show examples of apps that solve problems. This could include examples like a homework organizer, a community help app, or an environmental tracker. Encourage students to think of everyday issues they face.

Guide students through the brainstorming process. Outline steps to think about the problems they face, sketch ideas, and identify the target users. Encourage group discussions if possible.

Wrap up the lesson by summarizing the goal and next steps. Invite students to start sketching their app ideas and assure them that creativity is key. Provide encouragement and resources for further exploration.
