Teacher Developed Classroom Tested

Appropriate for Grades 10-11
Do your students find it difficult to remember how many ions go into a balanced equation?
These teacher-developed chips use the "tactile approach" when making compound formulas. Here's how they work: you suggest a compound, your students determine the formula using these color-coded, puzzle-like chips which represent the basic ions.
When trying to make sense out of ions, formulas and balanced equations, these chips can make quite a difference! Developed by Reed, Done and Fisher.
Includes: chips for a class of 30 students working in pairs, a teacher's set of magnetized chips, a list of suggested compounds and formulas, and a teacher's guide. (Please note: Some assembly is required.)
