I have created an interactive worksheet on a spreadsheet document. The worksheet continues with my unit on matrix operations and makes use of the formula function to demonstrate matrix addition, subtraction, and multiplication. However, instead of having the students simply repeat the formulas or solve the equation A #B=C where # is one of the three operations and have them simply solve C, I instead had C reflect the answer of the given A#B where B is a constant and A is to be inputed by the students. Additionally there is a key so the students know what C is supposed to be. This requires them to remember the formula and apply it in a different way, this diversity in application helps students comprehend the procedure more thoroughly thus acquiring greater conceptual knowledge as well. I hope to expand on this worksheet in the future, I don't believe it needs any other resources but I would really like to expand beyond 2x2 matrices given more time. Let me know what you think of the worksheet, I'll link a copy of the file below.
Here's the worksheet, however this is not interactive when posted as a web page.

But here is a link to it as a shared google doc, feel free to use it yourself.

But there are some quality more traditional worksheets available. This one by EdHelp.com has a little interaction as well.
