Print out the dinosaur line tracing sheets and cut them into their individual strips. Have your child choose their writing tool and first pattern to start with.
I suggest to laminate them and use with dry-erase markers so you can have a small group of kids do it together if you are in a preschool or daycare setting.
This would also be a nice busy bag game. You could punch a single hole in the corner and use a metal ring to bring it around with you.
