I made a ladybug even and odd number sorting that the children really liked working on. I printed the patterns on cardstock paper and and cut out the ladybugs and laminated them. I then cut out the leaf patterns and labels and glue them on colored cardstock paper (you could also use construction paper or just leave them as is after printing).
I set the leaf mats out along with the number ladybugs. Children sort the ladybugs by putting the even numbered ladybugs on the the even numbers leaf and the odd numbered ladybugs on the odd numbers leaf.
As of 2022 this activity can be found in the member's section which is also where I have added a ladybug upper and lowercase sort.
