How do I practise sentence classification with my SP HL class? Our Sentence Structure Activity — SP HL resource is a great tool to help your Senior Phase English HL learners practise sentence classification. The resource comprises two short exercises that can be printed for the learners to paste in their workbooks and completed as classwork or a homework activity. This Sentence Structure Activity — SP HL resource pairs well with our Sentence Classification: Clausal Structure — SP English resource. Both the Sentence Classification: Clausal Structure — SP English and the Sentence Structure Activity — SP HL resources can also be used to teach your Senior Phase First Additional Language (FAL) English classes about sentence structure.
