Explaining a task  revision of first two lessons (motion in one and two dimensions) and playing crossword game

Working in groups of 4. Solving crossword (Appendix A) Finding Key word to guess lesson topic 
Observing pupils’ work and results during crossword activity Q&A

Projector, Ipad, activity papers, smart board
