A literacy map, tracking document and a phonics poster. Both can be used as posters or on desks or given to students to place in books or to take home.
Connectives display posters, which I find incredibly useful for all year groups, especially during DIRT activities (I get the pupils to 'upgrade' their connectives). Common spelling error display also included in this pack. The third resource is a literacy map which I laminate and leave on the student's desks and I refer to this when we discuss writing up paragraphs etc.
I use this lesson as an introduction to history with all KS3 classes. Students are invited to pull objects from a bag and analyse the evidence before writing up their findings. This would also work well as a tutor time activity.
