Go to: (opens a new window)
Description: This interactive tool is one of a series of tools created by Conceptua Math that are designed for teacher-facilitated instruction. Teachers can use the Adding Fractions with Common Denominators tool to help students build a deep conceptual understanding of what it means to add fractions and to understand the term "common denominators" through the use of multiple models. Features such as dragging, hide/show models and linking models to procedures assist students in connecting conceptual understanding to the procedure of addition in a systematic and clear sequence when teachers begin by working with models only, models and numbers and then numbers only. Designed to work on an interactive white board.
