Dorian and Me (9/4/19)
See how I sweated out the coming of Hurricane Dorian in South Florida ... by constructing a calculus problem that dealt with its closest possible approach to my home. Show it to your students for them to understand how calculus can be used to solve real-life problems and make perhaps life-saving decisions. Cick on the link.
Calculus Conundrums (8/1/19)
Calculus Condundrums is a set of
9-question open-ended quizzes covering all topics in the AB and BC calculus curriculums in order. The kicker is that you cannot move onto the next question until you answer the current question. Question n + 1 depends on the answer from question n, so like a Rube Goldberg machine, all questions must be answered perfectly. With the questions covering the basics, even weaker students will enjoy this.
Calculus Conundrums is our new subscription and everyone who is a member of MasterMathMentor will receive the free student versions every two weeks starting September 5. But for those who cannot wait, the quizzes, solutions, and grading spreadsheet are available now. For more information, click on the link.

Test your Strength has been very successful for AB and BC Calculus as well as AP® Statistics. Our latest edition of it is a companion piece to RU Ready for AP® Calculus. It is meant to be given to students prior to them starting AP calc in order to give them a detailed report on the precalculus areas in which they are weak. In that way, they have the summer to reinforce those skills and walk into AP® calculus secure in the knowledge that their algebra skills are strong. Check it out by clicking on this link.
Calculus Acrostic (8/1/18)
Our subscription for the year is an acrostic game. In 2017/2018, we did a crossword puzzle game that gave students typical AP free response questions. This year's game focuses on multiple-choice. It can be used throughout the year as students solve clues to spell out a quote about calculus or mathematics. There are 3 different acrostics: derivatives, integral, and BC. Teachers enrolled as MMM members will automatically receive new clues every 3 weeks. It will be fun and challenging to play and a smart Excel spreadsheet can be used to give instant feedback. More information can be found by clicking on the link.
A Summer Math Problem
Did you ever have a dream about math? I do occasionally. I had this dream the other night that involved math calculations and I have no idea whether I was trying to do the calculations while alseep or in that limbo land.
The dream involved me running a workshop at a school some morning. For some reason, the particpants were only men. A similar workshop was run in another room for women. In both workshops, everyone was required to shake hands. In the afternoon, both groups got together and all the men shook hands with all the women.
For some reason in the dream, I was interested in whether there were more total handshakes in the morning or in the afternoon. Strange thing to dream about!
I tried to calculate whether there were group sizes when the total morning handshakes and afternoon handshakes were the same. I couldn't find any, but then, I was sort of asleep. It wasn't until I got up and 4 hours later, the dream came to me when I biking. I came home and put together a problem about it.
So concerning the number of handshakes, which is correct? More importantly, can you prove your answer?
(A) There are always more handshakes in the morning.
(B) There are always more handshakes in the afternoon.
(C) There are no group sizes where the number of morning handshakes and afternoon handshakes are the same.
(D) There is a finite number of group sizes where the number of morning handshakes and afternoon handshakes are the same.
(E) There is an infinite number of group sizes where the number of morning handshakes and afternoon handshakes are the same.
Think about it. If you would like the answer, click on the following link.

R.I.P. - Newton, the Calculus Cat
Newton has made a number of appearances in precalculus, calculus and statistics problems in my materials. Many students fell in love with his antics and in 2006, I decided to make him a part of the website. One of my former students Sam Tsui (now a huge YouTube singing star), drew him into our logo. And when I decided to have cartoons made for my products, Newton played a prominent role. He has been a biker, an archaeologist, and a teacher. He has dived into pools, helped a swami, joined a carnival, and hung from a catenary. He has left this world but he still lives in all these drawings. I won't soon forget him. He was my friend.
Change to Calculus Cache (10/1/17)
Because the AP® exam's multiple choice questions contain 4 choices, we have changed Calculus Cache so that all questions now have 4 choices. While the 5-choice version is available upon request, downloading the Calculus Cache student exam questions will get you the 4-choice version. Purchasers of the solutions in Word format can login and when they download the solutions, they will get the 4-choice version. They will also be contacted via email with the download links.

MasterMathMentor members will receive a new set of clues every week starting September 14. They will be in order of the AP® Calculus manual so you can give it to kids from day one of the course.

Clue game revision - 7/1/17
The calculus doesn't change but the suspects definitely do. In 2006, we had suspects like OJ Simpson, Paris Hilton, Usher, Kobe Bryant, Martha Stewart, Jack Nicholson, Michael Jordan, John Kerry, Donald Rumsfeld, Kate Winslett, Tony Soprano, Lance Armstrong, Nemo, George Foreman and Emiril Lagasse. What student would recognize these names today? The only remaining names from our original list is Tom Cruise, Bill Gates, and Hillary Clinton. So we revised the clue cards with more contemporary names in the news. Purchasers of the Clue game can email me at firstname.lastname@example.org and I will send you the revised clue cards.
