A new set of worksheets on converting between numbers in expanded form, written form and standard form have been posted. These sheets are great resources for learning both how to read and write numbers, as well as teaching place value concepts.
Part of the fun with math is just playing with numbers, but the numbers have to actually mean something to make it interesting. I call these “Math Riffs” as in many respects they’re just stream-of-consciousness runs of calculations, and while thought provoking, meant mostly for entertainment value. They’re the kind of things that I hope provoke a “Wow!” response from my kids, but sometimes I’m sure they’re thinking “Oh no… My Dad’s a geek!” or something similar. Oh well.

There’s a lot of numbers in my professional field, but they’re nothing like playing with big scary government sized numbers… the National Debt, the Federal Budget, the Gross Domestic Product, the Annual Energy Consumption… What? Last one didn’t ring a bell? Okay, fine… Let’s play!
According to the Annual Energy Outlook, the United States used approximately 73 quadrillion BTU’s worth of energy in 2006. Read the rest of this entry »
Just how hard will a kid work for some random bit of electronic widgetry? Say, one of the new shiny polychrome 4G iPods that His Steveness just showed off to us yesterday? It turns out, really hard. Especially when Engadget and everyone else starts leaking pictures of the brand new goods right before the deadline.
The oldest and I signed a contract a few weeks ago delineating exactly what she would need to do in order to score said gadget (we’re getting a little contract law education mixed in here, too.) To wit, the requirements included:
We set a goal of six weeks to get this all accomplished. This was definitely a stretch goal… A swing-for-the-fences, “Well, if you really want that you’re going to work hard for it” sort of task. I actually thought this might be the object lesson about over committing and not crossing the finish line, especially once school started and we hadn’t completed the last two items. Little did I realize, what was about to happen was a serious test of my ability to grade Rocket Math tests.
The stack of tests pictured here is 22mm high when compressed. A ream of the paper we use here is just over 50mm, so that would be around 220 pages. And if only that were all of them. That’s just the stack of tests from Saturday and Sunday. While that was definitely the big push before the deadline, there were at least that many in the previous weeks… Actually, I think I may have graded close to 600 pages of Rocket Math in the last month or so. Go ahead and quiz me on some basic subtraction. I dare you.
And yes, we’re headed for the Apple Store.
Thanks a lot, Steve.
We finally got to level L on RocketMath 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!
Welcome to the Rocket Math Spaceship Math home page at DadsWorksheets.com. Below you’ll find direct links to the Spaceship Math practice worksheets for all of the basic operations. Also, you’ll find a convenient web-based timer for administering practice tests.
Everything you need to rocket your kid’s math performance straight into orbit is below. If you find these materials useful, be sure to check out the rest of the math related content on the site. Good luck!
Please note that Spaceship Math is not the official RocketMath curriculum offered by R&D Instructional Solutions, and as per Dr. Crawford’s request in the discussion below, we’ve renamed the practice worksheets here as ‘Spaceship Math’ to avoid any confusion with the RocketMath commercial product.
