Teaching well with manipulatives means helping learners connect concrete representations with more abstract ways of presenting mathematics. This four-part series of webinars examines strategies for transitioning from manipulative-based mathematics to using abstract representations such as algorithms.

In this third webinar of the series, Dr. Sara Delano Moore shared strategies for helping students understand critical concepts such as common denominators and see connections between manipulative models and the algorithms we use to add and subtract fractions.
