This Year 4 Expanding Sentences Using Prepositions Application worksheet would be a great assessment tool as children use what they understand about prepositions and apply it to their writing.
This activity can be completed independently but could also be used as a discussion point for small groups or interventions. The worksheet comes with a model answer which can be shared with the children as a good example or to aid your marking.
