- [Homework](https://craigndave.org/homework/) - What is effective homework? Homework should help students progress their learning, otherwise there is little point to it.

There is a belief that homework “must be good for
- [Differentiation](https://craigndave.org/differentiation/) - Differentiation is the process by which differences between learners are accommodated so that all students have the best possible chance of learning.

Each workbook has four sections: Specification references. Activities. Assessment sheet. Revision checklist.
- [Structured learning records](https://craigndave.org/structured-learning-records/) - At GCSE we provide students with workbooks to capture their learning. When completed these ensured students had sufficient notes so that revision guides were not necessary. They became knowledge organisers.

- [Micro-activities](https://craigndave.org/micro-activities/) - For A level instead of workbooks we provide hundreds of micro-activities that teachers can use in a variety of ways: starters, independent learning, paired or teacher led work. A micro-activity will typically take students between 5-10 minutes to complete, so many are combined to create a single lesson. Teachers should be selective about which micro-activities
- [Lesson plans](https://craigndave.org/lesson-plans/) - Every GCSE lesson has a simple lesson plan in PowerPoint format that you can share with students on the board. There is no planning for the teacher to do. Simply ensure our resources are stored on your school network or VLE, project the plan and let the lesson unfold. Lesson structure Each lesson plan
