My 3rd grade daughter needs to work on her multiplication tables. I scanned the web for a spreadsheet that contained the 1-9 multiplication tables and could generate a worksheet with randomly blank cells, so she could learn the patterns. Kinda like a Sudoku. Short story, no luck. Long story, I built it myself with the Rand() function plus some truncation and use of If() function to set some cells to blank. Then just hit F9 to re-randomize to get a new worksheet to print.
Hope this helps some other parent.
Cheers
