K-3 refers to the educational system for children in kindergarten through third grade. This stage typically includes children ages 5 to 8, focusing on foundational skills in reading, writing, and mathematics. The curriculum is designed to promote social, emotional, and cognitive development, preparing students for more advanced learning in later grades. In K-3 classrooms, teachers use various teaching methods to engage young learners. Activities often include hands-on projects, group work, and interactive lessons. The goal is to create a positive learning environment that fosters curiosity and a love for learning, setting the stage for future academic success.
