Try "rref {{1,1,1,10},{.05,.10,.25,1.10 },{1,0,-2,0}}." If you simply provide your students with a link like this, they will have a template for entering a matrix, and soon will be using Wolfram|Alpha to compute determinants, inverses, eigenvalues, singular value decompositions, etc.

If you simply input a matrix, Wolfram|Alpha will identify interesting properties (e.g. orthogonal, toeplitz) about it.

But try "A collection of 10 coins consisting of nickels, dimes, and quarters has a value of $1.10, with twice as many nickels as quarters. How many of each coin are there?" Although Wolfram|Alpha handles row reduction, the student will still need to determine what matrix to enter and to interpret what information the row-reduced matrix provides.
