Writing Goals – Sentence Structure
Here is a proforma I used with my Year 5/6 class last year to explicitly teach the types of sentences that would be evident in a good quality piece of writing.
We spent lots of time practising writing these types of sentences in structured sessions, exploring these types of sentences in good quality texts and re-drafting sentences in students own work to reflect these.
These assessment sheets may be useful to keep track of student progress in relation to sentence structure. Let me know if any changes are needed. You may need to use several sheets and glue them together, depending on where your students are on the continuum.
