Particles .. Moles .. Mass 

The Particles .. Moles .. Mass Concept Builder includes three scaffolded difficulty levels designed to provide learners comfort with the mathematical relationship between the number of particles of a compound, the number of moles of particles, and the mass of those particles.  In each difficulty level, a five row table is presented with unknown cell values. Learners must determine the unknown values. Immediate feedback is given and chances for correction of incorrectly-inputted values is allowed. Help is provided for each difficulty level. Built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
