We started making personal time lines today. We ruled up our paper and marked 10yrs in 10 cm blocks. We had to work out elapsed time between our own birthdays and other events in our lives like our siblings birthdays. We found it pretty challenging.
We decided it would have been easier if we had 12cm blocks for each year. We are going to do our final time lines using 12cm blocks and writing in each month to help us figure exactly where each event needs to go.
