As part of our Build It Scotland Project, in our co – learning groups, we used timelines to put famous events in history from long  ago to quite recent. We used a  decades [10 years] and century  [100 years] for the most recent events and we used millennium [1000 years] for older periods in time [ the Egyptians for instance]. I had a lot of interest  finding out what the date was for each  card. It was great fun.
