Well, DadsWorksheets.com is now officially one year old. We’ve come a long way. We’ve seen over 300,000 visits to the site that generated over 2.25 million page views. And of course, 3,937 free worksheets.
We’re about to start another school year, which will be fourth grade and kindergarten here. I’m looking forward to the challenges that a new school year brings, and hope you’ll stop by to share in the fun. It will be great to see where we’re at in another year. Thanks for everyone’s support!

For years, Dad was a two-OS guy, with two computers (a Mac and a Windows machine) whirring away on the desk. I was multitasking before multitasking was even a word, but I did most of the day-to-day computing on a Mac. In fact, all of the business accounting still happens on an ancient PowerMac G3 that I’ve dredged out of the closet annually for the last decade or so. But, at some point it just made more sense to only upgrade, backup and power one computer, and since the day job involved building Win32 applications, there wasn’t much choice in which OS I wound up with. Until now.

Here’s a few quick worksheet updates to keep young math magicians busy!
The multiple digit multiplication worksheets have been updated to not include any problems where a multiplicand is one. We’ve been hitting multiple-digit multiplication pretty hard over the summer. It’s great review for the basic multiplication facts and keeps the mechanics of the multi-digit process fresh for when school starts back up. However, the 1xN digit worksheets, there was a 11% probability that a problem would have a ‘1′ in it. I’m hoping my daughter won’t notice that these “gimme” problems are gone now…
Not wanting to neglect the division operator, the recent updates include responses to a few recent user requests for more specific division series problems. You can now find division problems for doubles plus one as well as progressive division facts for small remainders in two new series of worksheets.
I hope your summer vacations are all going well!

We rounded out the school year with a taste of long division, which quickly exhausted the site’s light treatment of worksheets in this category. A few more fine tuned levels of difficulty, in addition to just a larger number of worksheets, have been added. Also, when we ran through several sheets here I noticed a large fraction of problems that had 1 as a divisor… Not exactly challenging for a division problem. These lightweights have been filtered out.
The answer keys for long division are especially helpful because they show the actual steps to solve the problem. Showing detailed answers to a long division problem is important given the number of different procedures and operations (and the corresponding opportunities to drive right off the road in the process of reaching the solution). The old Python logic that generates the long division answers worked in general cases, but was a little flaky in spots when multiple digits had to be brought down to satisfy the divisor in a step. It desperately needed refactoring, and the new solution is much more robust.
Significantly improved long division worksheets have been posted at the link below (or as usual, in the ‘Worksheets’ menu to the right), just in time for your summer review sessions!

As I type this, the calm clicks of the keys are punctuated once a minute by a sound I can most accurately ascribe to an evil, mutant cricket. It is the smoke detector at the top of the stairs, warning me that its battery is low. It has, in fact, been warning me quite urgently and persistently since 3:22AM this morning. I do not believe the timing is random, and I suspect it is actually, motive unknown, part of a sinister plan to do me in.
Having invested our full share to inflate the housing bubble, our home meets all of the recent building codes pertaining to fire safety. This includes a full complement of hard-wired smoke detectors — one in each bedroom, at the top and bottom of any stair way and in locations within hallways whose precise specification eludes me. The net result of this is that we have no fewer than nine smoke detectors in the house. I discern at a minimum that the authors of the current building code possess significant stock holdings in smoke detector companies, even if they are not fully complicit in the threats against my life.
