It's almost 2025

🎉As the new year approaches, this activity invites students to explore unique number categories related to 2025. What’s a Harshad number? A Pernicious number? A Tetrahedral number? Students will explore these concepts while practicing skills like understanding number bases (e.g., binary), using formulas, and finding patterns through visuals. 

This activity is perfect for wrapping up your final math class of 2024 or kicking off the winter break with something fun!

⏰ For younger students, it takes about an hour (including the starter activity).

For high school students, it’s can be a quick and fun warm-up or a great way to wrap up your last class before the break!
