Writing about personal issues is one of the best prompts to stimulate writing in primary. And to do so, it is always a good idea to scaffold with models and images.
Students of grade 5 described their rooms.
We started by making a long list of furniture, objects, toys and other items you can find in our bedrooms (vocabulary). Then we orally practiced expression of quantity with "there is" and "there are" and prepositions of place.
They took photos of their bedrooms and they brought them into the English class. They explained to friends about them. Then they wrote a description and make a big display in the corridor. Finally we uploaded to the school blog.
