This is adapted ppt I found on TES (thank you) - now includes loads of assessment opportunities as you go through - I was observed during this lesson and was rated outstanding. The game where the students have to say which food group someone is lacking or needs is done by giving all students 4 pieces of card - 1 red, 1 blue, 1 green and 1 yellow - I then explain the problem/situation and count down from 3 to 0, at 0 all students have to hold up coloured card that matches the required nutrient - great to quickly see who is struggling!
