Matrices as transformations
A matrix is usually shown as a box of numbers, but really it's a way of moving the whole plane, turning it, stretching it or slanting it, while keeping grid lines straight. You'll grab the two basis arrows and drag them, watch the whole grid follow, and discover that the matrix's columns are simply where those two arrows land.
