Our last day activities! It was a special day for the Kindergarten class to participate in Mass roles this morning, and end the year with their Alphabet Parade in the gym! We also had a variety show, signed yearbooks, and high-fived Thunderbolt on the way out the door!

Students know the end is near when the shaving cream comes out to clean the desks! It seems like the teachers also get excited for this day—not only because summer is near—they remember doing it as kids, too!

Our 8th Grade Class has had an amazing last week of school! They went to The REC to race the cardboard boats they made in STEM, and while some of the boats were not exactly fit for the open water, everyone enjoyed this culmination of STEM class with Mrs. Palmer.
They also journeyed together on their mystery class trip to The City Foundry in St Louis, for the Great Big Game Show and lunch at the Food Hall, followed by adventures at the City Museum, and then back to Belleville for a movie at the Lincoln.
They had their last day of class yesterday, so now there’s only one thing left to do…

Congrats to Mrs. Tammi Bottcher on 25 Years of teaching in Catholic Schools in the Diocese of Belleville!! That’s a whole bunch of middle schoolers—probably around 500!—that she’s taught in her classroom. And now two of those students of hers are also HTCS teachers!!
Congrats also to Mrs. Betty Stankey on her second retirement! She retired from full time teaching in 2016, and came right on back to school to work as an aide, continuing to help Holy Trinity students. We will miss Mrs. Stankey in the building, but we are so happy for her and wish her all the best!!
