I implemented a flipped classroom model during the pandemic. I would send pre-recorded video lessons to a class WhatsApp group, where students could work through the problems independently. Our online classes were then dedicated to discussions, allowing students to share their solutions and learn from each other's problem-solving strategies.

"I’ve heard that a picture tells a thousand stories. When I go anywhere, I always find some form of mathematics hidden somewhere. I often start my class by showing such pictures. This helps spark curiosity in children and gives them a space to be open, leading to great conversations. 

What do you think is hidden in the images below, mathematically speaking?"
