CREATE YOUR OWN PEDIGREE

SECOND STEP…

Page 16: March 29, 2012

If anyone is deceased, Make a diagonal slash mark through their circle or square.

Then use a Marker to Color in any family member with the trait.

If you do not know the trait for sure, you can take it home and complete it over the weekend.

THIRD STEP

Place a “key” at the bottom or side indicating what each shape means.
