Scrooge’s Missing Digits and Cartesian Art

First of all, Happy December and a Merry Christmas to those who celebrate it. Thank you for subscribing to this email newsletter which gives me a chance to highlight new and interesting things on I seem to have missed updating you about the Thanksgiving Cartesian Art worksheets, but it is worth a mention as several of them could be used at any time of year. The new Mayflower is especially worth a look. Following is a summary of some other math worksheets that I uploaded over the weekend.

Ebenezer Scrooge’s Missing Digits

If you’ve been keeping tabs, Math-Drills includes a lot of missing digits worksheets, but these ones are the first to be “fillable” worksheets. Here is what I wrote on the Christmas math worksheets page:

“Ebenezer Scrooge was so stingy that Bob Cratchit had to watch how much ink he used. As he was quite clever, Bob wrote each question so not only could he save some ink, but any other clever person could still figure out which digits went where. As we all know, Scrooge stopped being a miser, so he bought some ink, gave Cratchit the day off and is now going to fill in all the missing digits in the accounting ledgers. Can your students help Scrooge fill in the missing digits?”

The Scrooge’s Missing Digits worksheets are available for addition, subtraction, multiplication, division, and various mixed operations versions. Further, each operation can also be found in an easier and a harder version.

As with all “fillable” worksheets, students can open or download the student version (or the full version) in their browser or Adobe Reader, fill it out on the screen, and save it with their changes. These worksheets work equally well and don’t show the light blue shading when printed.

Christmas Graph Paper

Every once in a while, I come across an old worksheet that I made a long time ago and groan. This was the case with the old Christmas graph paper. It was desperately in need of an update, so I got out my rulers and created some new versions for both U.S. units and Metric units. With various clipart images to make it more “christmassy,” I made 1/2 inch, 3/8 inch, 5 lines per inch, 1 cm and 2.5/0.5 cm versions. Of course, graph paper can be used for all sorts of purposes. You can even plunk it down in front of your students and say, “be creative,” and they will likely come up with something interesting. You might even find that it is no longer hidden away in some other section; it has been promoted to its own section on the Christmas page. As with everything else, if there is a particular type of graph paper you would like to see, let me know.

Christmas Cartesian Art

I seem to talk about Cartesian art a lot, but there is a reason: it is popular. Especially at holidays, it is usually a very popular activity with Math-Drills users, so I keep making and improving it. I recently updated the Santa and Nativity Cartesian art, but there wasn’t a lot of changes, so they will likely look a lot like they used to with one important exception — there are student versions now.

The newest addition to the Cartesian art on Math-Drills is Snowflake 2. Snowflake 1 is kind of simple and uninspiring (but great for beginners), but Snowflake 2 is a four-quadrant geometric feat of engineering. Based on a real snowflake, this thing should be a great challenge to any capable student. It also holds the new record for having the longest continuous line (line 8) of any of the Math-Drills Cartesian art activities.

In case you missed it, you can see an entertaining video by Mr. West completing the Christmas Tree Cartesian art activity on YouTube.

If you made it this far, thanks for reading! Enjoy the upcoming holidays, and stay safe!
