Aidan smiled when he saw Brendan using the muliplication mat.  "Oh! You got out that thing-a-ma-jiggie!"  Yes, indeedy.  That OLD thingamajiggie is an idea I altered from the basic multiplication board in the Hainstock book.  It is cut from an inverted bathmat (the kind with lots of tiny suction cups) which has not fared well in storage across the ocean. The numbers 1-10 are labeled across the top.   You can easily drop pony beads or beans across the rows of cups to illustrate groups of numbers.  

(You can also use the bath mats to make Hundred Boards.  Just use a fine tip sharpie and write the numbers on the cups.)

Doesn't take long before you transition into a times table chart like this.  It is good to have some hands on work with the beads first so they can really visualize what is happening before they memorize the chart.

You can, of course use a printable, but when you realize just how far a pony bead can travel, and at what remarkable rates of speed, you become highly motivated to corral them. <g>

PS – you can print out multiplication problems here.   We are using inexpensive math workbooks and hopping around some for convenience.
