I have created a rubric using the 4x4 that's provided, but need to had several more rows -- the links provided do not show information with how to do it.
Hi Denise Beasley
It's very simple although not entirely intuitive so I've created the gif below to show exactly how you do it.
You simply need to roll your mouse over the "border-line" on the grid where you want to insert the row or column until the little ⊕ appears and then insert your new row or column.
