We finally got to level L on Rocket Math multiplication here and realized that level M was actually duplicated. This is fixed up… Sorry for any inconvenience there. Also, the new worksheet architecture is making it easier to create some new worksheet types. A set of greater than/less than sheets is up, including some that involve comparison operations with time. We’re over 1,400 worksheets up on the site now… With the infrastructure in place now, I think we could break 2,000 by the end of September!
