I know it's a little late for shamrocks but it's been a hectic week and these turned out so cute I decided to share them anyway.
Print two copies of the shamrocks on cardstock paper and then cut out and laminate them.
In this activity children find the same color shamrocks and clip them together with clothespins or paperclips. Play continues until all colors have been matched. You can download the shamrocks below:
