Hi and welcome, create a chart or table and decide which column will be age and which will be area of development then fill a content area with the information you've researched.
There is a
development thread here
The
search page can help - enter keywords from the criteria. A
handbook has useful information if you've access to a copy and your
home nations framework + guidance booklets will also contain developmental information to support this project.
If possible contact your course provider to see if they have a any advice for working through the unit.
Best wishes
