This worked for both St. Patrick's day and my journey's lesson 23 for suffixes -er and -est.
I had the students write a couple sentences as to why they are a lucky person. I then had them write something that would make them even luckier. Then finally in the final leaf I had them write what would or does make them the luckiest person in the world. When they finish their writing I have them cut out their hearts and their green clover. (clover printed on green paper) and glue their hearts onto their cloves.
