One teaching perspective that a teacher can use most often in teaching addition and subtraction lessons is the constructivist perspective. This perspective emphasizes hands-on learning and problem-solving, allowing students to build their understanding of mathematical concepts through exploration and discovery. Teachers can use manipulatives, games, and real-life examples to engage students and help them make connections between what they already know and the new concepts being taught. By actively involving students in the learning process, teachers can promote a deeper understanding of addition and subtraction and help students develop problem-solving skills that they can apply in various contexts.
