If you’re following the math curriculum, you know it’s not just about memorizing numbers—it’s about teaching children to think like mathematicians. In the 2nd-grade lesson on "Operations" (Операции) , students move beyond simple calculation to understand the structural logic of how objects change. What is an "Operation" in Peterson's World?
