Worksheet Fixes… Undo! Undo! Undo!

I gather entropy in the universe is supposed to be increasing. Turns out, around here, not so much.

Many thanks to JohnnyFourAces for pointing out that the randomness quotient of some of the worksheets had decreased in a recent update. For some of the “All Math Facts” worksheets, it went down substantially and centered on the earlier (easier) facts in the series.

Fixes for this have been posted, and additionally I added one and two minute timed worksheets to the Spaceship Math Multiplication Facts section to that include sets without the “times zero” and “times one” facts. Cutting these “gimme problems” really increases the density of more difficult multiplication facts and when your student is ready for these, any Mad Minute or Rocket Math timed test at school will seem much easier.

Happy Monday, everyone!

Multiplication Worksheets Updated

Learning multiplication is one of the big milestones in learning math. I’ve touched on it before and I imagine this won’t be the last time either. Your school may be using Mad Minutes or Rocket Math or similar timed drills to teach multiplication, but no matter how you approach it, learning multiplication is about worksheets. Lots and lots of multiplication worksheets.

This summer marked the start of teaching my youngest daughter her times tables, and even with the all the earlier worksheets on the site, we managed to identify a few gaps. Here’s a breakdown of the strategy we’ve been using and a link to our new favorite worksheet…

  • Master Dad’s 8 Rules for Learning Multiplication These sheets build the basic skills necessary to figure out the answer to a multiplication fact if it isn’t memorized.
  • Fill in a Multiplication Grid Worksheet at the start of big practice sessions. This can be used as a “cheat sheet” if necessary, but it also helps get some of the facts straight before the pressure of a timed test.
  • Drill with comprehensive worksheets. The current favorite is a new one we just added: 100 Problem Multiplication Worksheet, No x0, x1 or x2. Versions of this worksheet basically has all the easy multiplication problems stripped out, so it’s a great exercise for mastering the facts.
  • When we uncover specific multiplication facts that are giving us problems, we either use the Spaceship Math pages or the Conventional Multiplication Series worksheets to reinforce the problem fact.

Regardless of how you approach it, the site here has a a number of different worksheet series to help you. In addition to the new sheets without 0, 1 and 2 mentioned above, you can find new two minute practice worksheets in the conventional multiplication series at the link here…

100 Problem Timed Tests Posted

Well, the new school year has kicked off here and I’m leading a first and fifth grader this year through the math jungle. For my younger daughter, we’re starting back near the beginning of the material on the site. This’ll be a good opportunity for me to tune up and improve some of the worksheets we haven’t looked at in a while here.

Our fifth grader just started at BASIS Scottsdale, a local charter school with an outstanding reputation for rigorous academics. The organization runs schools at several locations in Arizona, and recently announced that former Intel chief Craig Barett has taken over as president and chairman of the board. We’re excited to be there… and just a little nervous. I just finished reading over the curriculum through high school graduation, and I can see differential calculus coming just a tad sooner than anticipated. Like 10th grade. Holy Liebniz, Batman!

For fifth grade, BASIS uses Saxon Math 7/8 and we’re off to a good start there. The initial diagnostic tests for the basic math operations are 100 problem tests given with a two minute time limit. For practice, I built a set of new worksheets that mimic the 10 x 10 Saxon layout and we’ve been drilling these here over the weekend.

Beyond the basic operations, it looks like the early part of the year covers a lot of percentages and ratios, so maybe my eagerness to get away from fraction-related content may be premature. Either way, we’ll have fun!

Meanwhile you can find the new 100 problem, two minute timed tests at the links below…

100 Problem Two Minute Addition Tests
100 Problem Two Minute Subtraction Tests
100 Problem Two Minute Multiplication Tests
100 Problem Two Minute Division Tests

Also, the ‘All Problems’ addition tests have been updated to include variants that don’t have the ‘X+0′ problems. This should create some more rigorous worksheets for memorizing the more difficult facts.

General Worksheet Improvements, More Fractions Coming!

The number of new worksheets posted has been a little slow lately, but that doesn’t mean there haven’t been a number of useful changes. The worksheets on the site have all been refreshed and I think you’ll find a number of sheets are more useful.

A Guide to the Division Fact Worksheets

Well, the new school year is officially underway. We touched division last year briefly, but fourth grade here is where we need to get our division facts down cold. Of course, the goal is working up to those long division worksheets but to get there, you really need to establish a solid grounding in the division facts first.

Unfortunately, division isn’t just multiplication in reverse. Oh yeah, we tell them that and it flies for a while, but then one ugly left over spoils the fun. Remainders. You only get so far into division before this remainder thing pops up, so if you arm your kids with only the “reverse the multiplication” strategy, division quickly develops a reputation as the nightmare operator. We relied heavily on the idea that addition and subtraction had “fact families” and you could always reverse them, but that clean relationship just isn’t there for multiplication and division. I mean, what’s the corresponding multiplication fact for 5 / 2 = 2 r 1 ? 2.5 x 2 ? We don’t get closure here until we’ve introduced fractions and decimals… Perhaps division’s reputation as a monster is a bit deserved. Either way, this post describes the various sets of division worksheets on the site to help you introduce division and remainders successfully.

Rocket Math Worksheets are Now Spaceship Math

Rocket Math

Dr. Donald Crawford paid a visit to last week and suggested perhaps renaming the worksheets posted here to avoid conflict with the commercial Rocket Math curriculum he has developed over at You can read the discussion at the bottom of the Spaceship Math Strategy post, but given that this is supposed to be a low-stress activity on my end, changing the names of the worksheets to address everyone’s concern was definitely easy.

Meanwhile, if you’re a teacher looking to purchase a full curriculum for Rocket Math, be sure to check out Dr. Crawford’s new web site at the link above.

An Overview of Spaceship Math

Rocket Math Rocket

Welcome to the Rocket Math Spaceship Math home page at  Below you’ll find direct links to the Spaceship Math practice worksheets for all of the basic operations. Also, you’ll find a convenient online timer for administering practice tests.

When learning the multiplication facts, having a multiplication chart or copies of the times tables on hand to provide a self-help reference for students working to memorize these facts. These charts can also be used to “work backwards” to find division facts, which is a great way to reinforce the relationship between the multiplication and division operations.

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. Educators interested in buying the Rocket Math materials for use in their classrooms are encouraged to check out for details.
