|Go to:||http://www.conceptuamath.com/fractions.html#AddingUD (opens a new window)|
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 Uncommon Denominators tool to help students understand the terms "common denominators'' and ''uncommon denominators''. Students learn how to determine a common denominator for two given fractions with uncommon denominator by multiplying one or both by a fraction with a value of 1.
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.
