PROBLEM POTPOURRI ANSWERS ARE POSTED!

Also posted is the grade sheet as of 12/6.

1) Please check to see that if you turned in your project and your Fear of Math essay, they have been registered. Things came in in so many formats that I am not convinced I got them all.

2) Make-up assignments for people whose Groupwork or Assignment average was below 80% are posted on the left. Those of you who fall in that category will be receiving an e-mail telling you which of the make-up assignments to turn in. If you do not receive an e-mail, send me one!

REMINDER: The Final will be from 4:30 to 6:20 Monday in our regular classroom.

I plan to post answers for the numerical problems in the Problem Potpourri on Sunday afternoon.

As in the case of the mini-test, a grade below the cut-off point requires action in order for you to receive credit. If your grade was below 70, you must get a copy of the make-up version of the test and give it to yourself. Give yourself all the time you want, but don't work with anyone else. Once you are done, you must bring it to Stephanie or me and go over it with us. We will ask you to talk through your solutions to some of the problems. If it seems to us that you need some more work to solidify your understanding, we will give you more work to do. All of it is material that I consider essential, and furthermore a lot of it will turn up on the final -- it definitely needs to be well and truly nailed down.

Assignment 3, due Monday, 10/8

1) Read the book introduction. If you are not one of the lucky 12 who nabbed a printed copy of the textbook, you will need to download it from the file on the left. NOTE: The file the publisher sent me includes the table of contents, which you don't need. All you need is pages 1 - 11

2) Write a one page (or thereabouts) reaction to it -- what sounds appealing? what sounds alarming? what is the same as you previous experiences? -- or whatever else you would like to say about it. Send it to me by e-mail -- cc'ed to Stephanie and with 170 Assignment 3 in the subject line.
