Making a family tree is an excellent project for children. They can draw pictures, cut/paste photos, write names and familial relationships, add birthdates, and decorate the chart.
You can use the family tree below as inspiration, or download the PDF to use as it is.
Children can also begin with making individual cards for family members. These cards can be arranged into a family tree on a corkboard, or pasted onto a large chart later.
Let your imagination guide you!
