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!

The addition worksheets for fractions are
posted here, and if we optimistically consider only the four basic math operations, that means I’m a quarter of the way through fractions. Fortunately we only touched on fraction addition this year, so that probably gives me the summer break to get geared up for fourth grade math. I’m certain that’s going to cover a lot more of our fractional friends.
The worksheets recently have taken more effort mostly because they show detailed problem steps in the answer keys. You’ll notice on some of the more complex variations of these fraction worksheets (mixed fractions and uncommon denominators) where we break down intermediate calculations to reach the answers. This really helps with “self grading” of the worksheets because your young mathematicians can see where their calculations went off the rails.

Somewhere out there I’m sure there’s a guy whose job is just to come up with crazy sounding names for all the shapes in the geometry zoo. Worse than the guy who names bacteria. But I suppose, better that than working out all the equations needed to compute key measurements for all those mangy beasts.
Fortunately, we’re starting near the bottom of the geometric food chain. After all, what’s less complex than a shape with exactly one side? Of course, that’s our friend, the perfect circle… The single-celled organism of math. Circles are special in that given one dimension, you can determine all sorts of interesting facts. Got a radius? You’re a few multiplications away from a diameter, area and circumference. And if your basic algebra kung-fu is strong, you can go from area to diameter to radius to circumference just as easily.
Given all the interesting tricks you can do with circles, it’s no surprise how big a role simple circle geometry plays when you start getting into trigonometry. Which is all the more reason for getting the basics down early, and hence the healthy collection of circle geometry worksheets at the links below. Enjoy!
