This is the IXL award grid. It consists of 72 squares (8×9). As you can see it is almost full. The awards with the question marks are the only ones I can discover, which are mastering (skill amount) skills and answering question numbers in the thousands, E.g 4000 questions. When an award says ‘complete any row’ or ‘complete any column’, it means you need to complete an award row/column on the grid.
