If you teach 5th or 6th grade, you know the beginning of the year is all about building routines and setting the tone. It’s also the perfect time to try a back-to-school reading activity for grades 5 and 6—something fresh that gets students talking, collaborating, and thinking critically across subjects.
These hidden message back-to-school activities combine science and reading in a way that feels more like solving a puzzle than completing an assignment. They’re low-prep, high-engagement, and great for kicking off cross-curricular learning right out of the gate.
Free reading goldmine
Before diving into the activity itself, I have to mention one of my favorite free resources—ReadWorks.org. If you haven’t explored it yet, it’s a must-have in your toolkit. The platform offers hundreds of leveled articles on every topic you can imagine, from coral reefs to space missions.
What makes it especially helpful for upper elementary:
- Each article is leveled for easy differentiation
- Built-in audio support for accessibility
- Ready-to-use comprehension questions and vocabulary sets
- Great for science, social studies, and beyond
Whether you’re planning cross-curricular reading or just need a solid article to anchor a lesson, ReadWorks has you covered. It’s the backbone of these hidden message activities—and an absolute gem even without the puzzles. Ready to see how this resource translates into an engaging lesson? Let’s dive into what’s inside.
What is inside?
Students read a science article (from ReadWorks.org) and answer comprehension questions using task cards. Each correct answer reveals a letter, and once they’ve got them all, the fun really begins—they’ll work together to crack the code and uncover a hidden message.
Along the way, they’ll:
- strengthen science vocabulary and reading strategies
- collaborate to decode clues
- ease into classroom routines through a hands-on challenge
Perfect for groups, pairs, or even stations if you’re feeling adventurous. Plus, the print and digital formats make setup a breeze whether you’re in a traditional classroom or teaching with tech.
Grade-level specific
These versions have been tailored to match the reading levels and science topics that resonate most with upper elementary learners. The 5th grade edition leans into hands-on discovery, while the 6th grade version emphasizes collaboration and problem-solving.
