Making Arrays

Our introduction into finding all possible arrays

An example of our T-Chart to help keep us organized

As we continued our discussion on arrays, we tried to come up with a way to determine if we'd found all the possible arrays for a number. First we talked about what those arrays are actually modeling (factors). Then we came up with our T-Chart to list out the factor pairs in an organized way. We can determine we're done when we begin repeating numbers. All this discussion is leading up to 2x2 multiplication.
