Running Head: How Large Denominators Are Leading to Large Errors 1 How Large Denominators Are Leading to Large Errors

When it comes to fractions and working with them, they can be difficult to understand. Through our research, we attempted to bring a greater understanding to how we as individuals learn fractions. With this, we can move forward to teach fractions in a way that lets us have a better understanding of fraction magnitudes and how to work with them. For our study, we tested three hypotheses. First, ...
