Happy World Bamboo Day! 🎋
Some types of bamboo can grow up to 35 inches in a single day.

Bamboo: 1
Me: 0 😂

📚 The Evolution of Classroom Technology

I still remember the green chalkboard, the overhead projector, and the boxy classroom computer that sat mostly unused in the corner. They weren’t flashy—but they were the backbone of learning in their time.

Today, it’s Chromebook carts, Google Classroom, and touchscreens everywhere.

The shift from analog to digital hasn’t been easy—but it’s fascinating to look back and realize just how far we’ve come.

Sometimes, you stumble upon a tool that makes you think, "Where has this been all my teaching life?" That’s exactly how I felt when Markify followed me on BlueSky.
