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!

With the end of the school year on the horizon, the spectre of trapezoids, parallelograms, and scalene triangles has reared its head in 3rd grade math. The task seems to entail more than just helping my daughter… I couldn’t quite remember if a square is technically a rhombus or not. Clearly it’s time for Dad review as well. It looks like we’re going to skim the outer edges of geometry this year, so the initial worksheets focus on identification of concepts more than calculation, but I expect this section to grow substantially over time.

The new worksheets this pass focus on identifying types of angles (acute, right or obtuse), perpendicular or parallel lines, classification of triangles and classification of quadrilaterals. There’s also a few basic worksheets on identifying types of polygons.  And, yeah, squares are actually special cases of both rhombi and trapezoids. And convex bicentric parallelograms. I hope you are hanging in with me for emotional support by the time trigonometry comes around because the review may kill me.
