Christmas with Alexandria Jones

Alexandria JonesAlexandria Jones and her family are fictional characters from my old Mathematical Adventures newsletter. Their stories appear sporadically as I find time to transcribe them from the back-issues. You can find them all on this blog page.

Here are all the Alexandria Jones stories Christmas stories, with activity and craft ideas…

Alexandria Jones and the Christmas Present Quandary

Alex designs tessellation wrapping paper, hunts for the perfect Christmas tree, and comes up with a lively present for her brother. We meet the rest of Alex’s family — her father was introduced in an earlier issue — along with historical figures Maria Agnesi and Leonhard Euler, and we take a brief glance at mathematics from China.

Alexandria Jones and the Christmas Gifts

Most of this issue focuses on other topics — but the Jones family has a new baby, so Alex makes two gifts.

…And coming soon: Alexandria Jones and the Magic Christmas Cards. Stay tuned!

What Do We Mean by ‘Understanding’?

“You understand something if you have the ability to view it from different perspectives.

“Changing your perspective makes your mind more flexible, it makes you open to new things, and it makes you able to understand things.”

— Roger Antonsen
Math is the hidden secret to understanding the world

Hey, Blogger, Can You Spare a Time?

Do you write an education or family blog? Classroom teacher, math coach, homeschooler, parent, college professor, unschooler — anyone interested in helping kids play around with math? Please consider volunteering to host the MTaP blog carnival for one month.

We need volunteer hosts for most of 2017.

You choose the month that fits your schedule and decide how much effort you want to put in. Writing the carnival can take a couple of hours for a simple post — or you can spend several days searching out and polishing playful math gems to share.

If you want more information, read the MTaP Math Education Blog Carnival home page. Then let me know which month you want.

Count Up to Christmas

primary_houses

secondary-starBack when we were still homeschooling, I always dropped the “regularly scheduled program” in December. School plus holiday prep added up to one stressed-out mom.

Instead, we read plenty of library books. And we played around with informal activities like the NrichMaths Advent Calendars:

For older students and adults, the online Plus Magazine offers a calendar of daily tidbits from their “Maths in a minute” series, explaining important mathematical concepts in just a few words”

And for still more winter fun, check out the links in my old Christmas Math Puzzles and Activities post.

And a Question for You

How do you handle schoolwork during this busy season? I’m collecting new links for an updated Holiday Math post next month. I’d love to hear your ideas!

Giving Thanks

Thanksgiving at the Trolls

Proclamation 106—Thanksgiving Day, 1863

Portrait

By the President of the United States of America

A Proclamation

The year that is drawing toward its close has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added which are of so extraordinary a nature that they can not fail to penetrate and soften even the heart which is habitually insensible to the ever-watchful providence of Almighty God.

In the midst of a civil war of unequaled magnitude and severity, which has sometimes seemed to foreign states to invite and to provoke their aggression, peace has been preserved with all nations, order has been maintained, the laws have been respected and obeyed, and harmony has prevailed everywhere, except in the theater of military conflict, while that theater has been greatly contracted by the advancing armies and navies of the Union.

Needful diversions of wealth and of strength from the fields of peaceful industry to the national defense have not arrested the plow, the shuttle, or the ship; the ax has enlarged the borders of our settlements, and the mines, as well of iron and coal as of the precious metals, have yielded even more abundantly than heretofore. Population has steadily increased notwithstanding the waste that has been made in the camp, the siege, and the battlefield, and the country, rejoicing in the consciousness of augmented strength and vigor, is permitted to expect continuance of years with large increase of freedom.

No human counsel hath devised nor hath any mortal hand worked out these great things. They are the gracious gifts of the Most High God, who, while dealing with us in anger for our sins, hath nevertheless remembered mercy.

It has seemed to me fit and proper that they should be solemnly, reverently, and gratefully acknowledged, as with one heart and one voice, by the whole American people. I do therefore invite my fellow-citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next as a day of thanksgiving and praise to our beneficent Father who dwelleth in the heavens. And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings they do also, with humble penitence for our national perverseness and disobedience, commend to His tender care all those who have become widows, orphans. mourners, or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty hand to heal the wounds of the nation and to restore it, as soon as may be consistent with the divine purposes, to the full enjoyment of peace, harmony, tranquillity, and union.

In testimony whereof I have hereunto set my hand and caused the seal of the United States to be affixed.

Done at the city of Washington, this 3d day of October, A. D. 1863, and of the Independence of the United States the eighty-eighth.

Abraham Lincoln
