Here are some resources to help you with your topic work. There is a link to the BBC class clips website for lots of information to get you started and some PowerPoints and activities to do.
A good starting point would be to look at the PowerPoint introducing the Ancient Greeks, labelling a blank map of Europe, labelling a map of Ancient Greece and ordering a timeline of key dates and facts.
You could then explore different aspects of life in Ancient Greece, such as sport - the Olympics, the Greek alphabet, gods and goddesses, Greek art- designing a vase or Ancient Greek homes or food. You could also compare to the way the Vikings lived - what was the same or different? Also Purple Mash has some information and activities to do in their topic section.
