"Federico was spying for the Union army. But he wasn't perched on a tree limb or lying flat on a hilltop. He was balancing inside a wicker basket hundreds of feet in the air."

Meet Federico Fernández Cavada, a true testament to Caribbean American Heritage Month. Born in Cuba and raised in Philadelphia, Federico's artistic talents led to his assignment to the Hot Air Balloon Unit of the Union Army to sketch enemy movements.

But his fight for freedom didn't end there. Federico later returned to Cuba as a general in the fight for independence from Spain.

One incredible life. A whole world of history packed into one unforgettable story: "Federico Fernández Cavada: The Spy in the Hot-Air Balloon," a Voices in History biography.

School Spotlight 🌟 LHUSD #1 (Lake Havasu Unified School District, AZ)

The best teaching ideas come from other teachers. And this community has some of the best!

A+ School of Excellence designations. ACT scores rising year over year. And first graders expanding the vocabulary of their older siblings.

That's what knowledge-rich education looks like in practice.

Music education shouldn't be a line item that gets cut. It should be a foundation every student builds on starting in kindergarten.

That's why Core Knowledge Foundation has launched CKMusic: a free, K–8 music curriculum designed to make rigorous, joyful music education accessible to every classroom, in every district, regardless of budget.

CKMusic gives teachers a structured, no-prep framework for building genuine musical knowledge not just exposure, but deep understanding that compounds year over year.

What teachers love about CKMusic:

🔹 Grade-Level Spotify Playlists: Carefully curated playlists for each grade level — Just add to your classroom queue.

🔹 Listening Prompts That Build Knowledge: Structured discussion prompts guide students from noticing instruments to identifying composers, recognizing musical forms, and connecting music to history and culture.

🔹 Cross-Curricular Connections: CKMusic is designed to reinforce what students are learning in history, literacy, and social studies because great music education doesn't happen in isolation.

🔹 All-In-One Lesson Support: Everything teachers need is included. Structured, sequenced, and ready to use from day one.

Students who study music build stronger listening skills, richer vocabulary, and deeper cultural knowledge, and CKMusic makes it easy for every teacher to deliver that, every day.
