One of my favourite teaching tools is the multiplication grid!
You can start with a simple 5 x 5 grid in order, move onto a 10 x 10, then as children become more and more adept at their times tables, you can put the numbers out of order (this is when they are relying less and less on their number patterns and are getting much better at other strategies).
Here is a little look at a rainbow grid, not perfect, but carefully done! These can be done quickly in lead pencil during a middle session, as well. They can even be done on holidays, like Sudoku ... I'm sure there's nothing that will thrill your homeschoolers more ;) Enjoy
