Module 3 Understanding Addition & Subtraction

As you begin your journey to becoming a teacher, it's essential to revisit and master the basics, starting with addition and subtraction of whole numbers. You may already feel comfortable with these operations, but this module goes beyond just getting the right answers. It’s about understanding how and why these operations work so you can one day explain them clearly and confidently to your own students. They are the building blocks of everything from solving everyday problems to complex calculations in science, business, and technology. As an educator, your students will look to you for guidance and clarity. The ability to teach foundational math with confidence and adapt your explanations to meet diverse learning needs starts with your deep understanding. This module will help you strengthen not only your own skills, but your ability to guide others in building theirs.
