Why doesn’t Rocket Math go to 12×12=144?

Yes, Rocket Math now does “go to 144.”

Hi there,
I was wondering if you’re going to have Rocket Math go through 144 ever. If not, I was wondering if you could give me the rationale as to why you don’t. Thank you and have a great day!

Hello Valerie,
That is a good question and thank you for asking. I am going to send you a free one year Universal subscription to Rocket Math, because I can guess that you don’t have one, and because I can tell you’re obviously a devoted Rocket Math user.

Rocket Math licenses (the way we used to do business) provided only 1s-9s in the four operations. Now we have subscriptions instead. While the basic subscription only provides access to the 1s-9s of the four operations, I have much more in the Universal subscription. The extra drawers that are part of the Universal subscription include Multiplication 10s, 11s, and 12s (including 12 x 12 = 144) and Division 10s, 11s, and 12s. These programs are meant to be done after the 1s-9s are learned, and include a hefty dose of review of the 1s-9s facts along with the new facts. You can see an example of Set J above.

But wait! There’s more! The Universal subscription drawers include Add to 20 (13+6, 4+11, 15+5), Factors, Integers, Rocket Writing for Numerals, and Skip Counting. I’m working on Subtract from 20 as well, which will be added to the Universal subscription as soon as it is done. One of the joys of the subscription is that I can add new programs and make them available immediately to my customers, that they can see whenever they go to their “Filing cabinet on the web.” That way I won’t ever have long time customers who don’t know what is available. You see, I made those 10s, 11s, and 12s a couple of years ago, but you never knew. Thanks for asking Valerie, and thanks for being a loyal Rocket Math user!
