These are TWO SETS of 10 cards that portray a family's pedigree for one trait. They are formatted for Avery business cards product number 8871 but you can print on card stock and cut out just as easily. I feed the paper in once, flip it, then feed it again. Shuffle the cards and have small groups of students (2-4) figure out the "puzzle" and draw the pedigree. Some people's traits in the family are specifically written and others can be inferred based on the lineage. Answer keys included. Have students come up and check when they finish. I use them both in class or for students that may be struggling and need to work during a study hall or after school. They can take the pack with them, then bring them back to me to check the answers!
