Story Board for my open class

I'm planing reading and writing class through a story which is related with the topic for my open class. The topic is 'Do you want some more?' The object is that students are able to read and write the expressions 'I like ....', 'Do you want some more?', 'Yes, please.' and 'No, thanks.' In order to achieve it I'm making the core lesson plan like this. First, Teacher tell a story without pictures. Students just listen to the story and do a listening activity with this worksheet to check how much students comprehend the story. Then, students read it together with pictures and check if they're right or not. After reading, students can make their own story using 'at my house' corner in the worksheet.Students can write their story and read it their individual story connecting to the original one. Students also should practice writing key expressions correctly through 'Broken sentences' activity. So they can catch their mistakes and fix them by themselves. I'm not sure how it works to the students.I'll try it and make up for unexpected mistakes.^^
