@SmartmanApps Yes, one thing at a time. And instead of teaching a formula to memorize, without any understanding of how it came to be, what should be taught is that understanding. This is as easy as teaching kids addition: here’s a shape, there’s a shape, oh, and look, a third shape that is the exact same size as the first. And each of those shapes have an area calculated by multiplication, which they already know. Build upon prior knowledge.
