This post contains an electronic version of Spitballs From the Back Row’s appendices, for those who wish quicker access to the links.
APPENDIX 1: RESOURCES & MORE INFORMATION
- In Section 1, p. 24, the footnote mentions a resource used to pattern the ‘quiz’ in that essay. Here is a link to the original book, from National Council of Teachers of Mathematics. It is the best book on the general topic I’ve seen. It is not only readable, but provides a wonderful perspective and things to ponder.
- In the Education in an Information Age essay (Section 3, p. 64), there is a Doonesbury cartoon mentioned. It’s amazing to me how successfully that particular strip captures the essence and perspective of this topic, while simultaneously mixing in humor. It is perhaps my favorite ‘educational topic’ cartoon strip. The link is provided in the piece, but here it is again:
- Notwithstanding the cartoon strip mentioned above, there /was no cartoon strip I know of that matches the sheer volume of excellent-while-humorous educational (and mathematics educational) cartoon strips than Calvin and Hobbes. Again, the humor helps drive home the thought-provoking points. Check out this site for a large collection of samples:
- As to “the answers” to the Poetry/Mathematics quiz at the end of Section 4 (p. 89-92), here is the quick version: All the odd-numbered quotes refer to poets/poetry, while all the even-numbered ones refer to mathematicians/mathematics. For the original version of the article, check out the link below. (This is a long (and perhaps surprisingly ‘academic’) article, but the quiz and answers are given in Appendix B at the end.
- Further/ongoing resources. Preferably, this section can take on an ongoing and growing nature through the author’s website(s). If readers have questions or comments, feel free to use the connections and information detailed in Appendix 2. Resources that grow out of those inquiries and from other places will be added to the list, which can be periodically checked. Feel free to check back often.

APPENDIX 3: ASSORTED BRAIN TEASERS
Also known as “Yoga for the Mind”
“Brain Teasers” are wonderful tools for the budding problem solver in mathematics and elsewhere, but they are not For Math Nerds Only! They can be a great deal of fun, as well. Listed below is a sort of “Top Ten” of some Easy-To-State Favorites, after which some links will be provided to others, as well. Lighten Up. Pick (only) the ones you that grab you, and by all means, have fun!
- The Horse Trader
A man buys a horse for $60, sells it for $70, buys it back for $80, and finally sells it for $90. Did the make any money on the transactions, and if so, how much?
Ten people enter a room for a meeting. If they all shake hands with each other (once each), how many total handshakes will there be?
- Dollars and “Sense”
In my hand, I have two common US coins whose total value is 55 cents. One of the coins is not a nickel. What are the coins?
- Calendar Cubes
How are the digits 0 – 9 placed on two cubes to form a calendar (often seen in banks, etc) that can display every date of any given month? (Always use both cubes: 01, 02, 03, . . . 30, 31)
- It’s All “Relative”
“Brothers and sisters have I none, but this man’s father is my father’s son.” To whom is the speaker referring?
- Buckets of Water
You have TWO completely unmarked buckets. One will hold exactly 7 gallons, the other 4 gallons. How can you measure exactly ONE gallon of water? (What if the smaller bucket holds 5 gallons instead?)
- Number Sequence?
What are the next two letters in this sequence? O, T, T, F, F, S, S, ____, ____
- The Frog in the Well
A frog is at the bottom of an empty 30 foot well. Each day he is able to climb up 5 more feet, but at night, he slips back 3 feet. At this rate, how long will it take him to escape the well?
- The “Average” Driver
Ralph drives 60 miles at an average speed of 30 mph, then returns over the same route at an average speed of 60 mph. What was his average speed for the round trip?
- Word Trivia
Consider the spellings of each positive whole number. A) Which number’s spelling is the first to contain the letter A? B) Which number’s spelling is the only one in alphabetical order? C) Which is the only one in reverse alphabetical order?
