Unity in Division
What is the thread that holds division facts together? Are divisibility rules just mantras or can they be reasoned out, and perhaps, even arrived at?
In Divisibility Rules and DADS Rule! we start with rules which seem like sheer magic and then we understand why they work! Mathematics is just this – observation, pattern recognition, reasoning and justification! And the more visual the argument, the more sense it makes to most students!
