Students need to be in groups of 4 with each students labelled a, b , c or d. All four students work together to complete the introduction, ending with a final question that gives two choice eg Do they go to the kitchen or into the backyard? The groups then split into pairs, eg a and b writ e the story continuing into the kitchen while c and d write the story continuing into the backyard. Again, both groups finish with a question with two choices. Students then individually complete the story. Each group needs the complete set of 7 worksheets to write their story. I like to have the groups write each part on a separate day, so it would take 3 days to complete.
