For younger children, we ask them to draw a big picture of their grandfather on this worksheet, then fill in some details. Fun for Grandparents' Day perhaps, or a Family theme.
Grandfather Worksheet 1
Here's an interesting variation on the family tree for older children, who can fill out several generations. It really helps them to understand where they come from and give them a sense of history.
Fill in the blanks on this family tree and add a small picture or photo of the different family members in the circles. It's a fun way to introduce the family tree concept to kids!
