[Do you have Dolciani Prealgebra handy?]

I'm late but for future reference.

1970 version
Modern School Mathematics
PRE-ALGEBRA
Dolciani, Wooton, Beckenbach, Chin, Feldmen, Markert

I own them but the 1970 versions have no ISBN.
The teachers edition has the classic green teachers manual at the front.
This edition has much more set theory and other "new math" features than the later editions.

[I need the isbn for TE or solutions manual for Dolciani Geometry c. 1972]

One copy, not exactly the one you're looking for at Amazon:

 

Solution key for Modern geometry: Structure and method

(Houghton Mifflin modern mathematics series)

 

Unknown Binding: 245 pages

Publisher: Houghton Mifflin (1965)

 

http://www.amazon.com/gp/offer-listing/B0007GQY3O/ref=dp_olp_used_mbc?ie=UTF8&storeAttribute=b&submit.see-all-buying-options=see-all-buying-options&condition=used

 

These are all very rare. The 1965 version solution key is more common then the 1969/72 version from my experience. A 1965 student text is pretty easy to find.

 

The 69/72 version has code 2-28797 on the back but will be nearly impossible to find.

[Lessons Learned on the older Dolciani Editions]

A rare teacher edition (MODERN ALGEBRA AND TRIGONOMETRY, STRUCTURE AND METHOD, 1963) has appeared on abebooks for 20.00 in very good condition.

I'm not the seller and have no connection. I would just like someone here to get it (I already own a copy).

[Mathtutordvd.com question]

I feel bad nobody has answered so I’ll make an attempt.

 

I think highly of Mathtutordvd but first things first.

 

You really haven’t provided enough information. I presume that your daughter has only January because there’s a class she’s taking in February? If that class is calculus and your daughter is weak in algebra maybe she should defer calculus if possible. Then in the summer she could review more and even try to get a head start on calculus.

 

The central question is how much algebra she already knows and what spring class does she need it for.

 

I’m also concerned that a college with no math classes before calculus is probably a competitive school. The Mathtutordvd courses to prepare for a rigorous calculus class would also need to include “The Advanced Algebra Tutor†and “The Trigonometry & Pre-Calculus Tutorâ€.

 

Mathtutordvd has great explanations but without doing homework type problems that information will quickly fade from memory. One possibly is to find an older / cheaper edition of Algebra and pre-calculus that has an associated student solutions manual. Lial is often recommended on this board. Then try to match problems in the book and solution manual with topics on the DVD. It looks like Mathtutordvd also has some Algebra 1 and 2 worksheets that could be useful. Again, watching lectures without solving problems on paper will not be enough.

 

There would be more options if there was more time.

 

Again, if she is weak in algebra and about to take a rigorous calculus class this would be a big problem.

[TI-84 Calculator Question]

To use one y function inside another use the “vars†key.

1) press vars key (left of the clear key)

2) right arrow to Y-VARS

3) press enter

4) down arrow to 1:Y1

5) press enter

This will insert function y1 into the equation you are currently editing.

[Talk to me about Euclidean Geometry]

I’ll describe my current geometry project. I did take geometry in high school and did very well but I’m also old and forgot quite a bit of it.

 

I’m using two DVD courses:

 

1) Geometry Help: The Geometry Tutor -- 2 DVD Set -- 9 Hour Course

http://www.mathtutordvd.com/products/item16.cfm

 

This course is about concepts. *Very* basic but it got me warmed up.

 

2) High School Level—Geometry Taught By Professor James Noggle

 

http://www.thegreatcourses.com/tgc/courses/course_detail.aspx?cid=105

 

This should be bought when it’s on sale. The sales happen pretty often.

 

More challenging, this is a very good course in the sense that the postulates, theorems, properties, and definitions are consistent and well thought out. This course is all about proofs which are done with some welcome precision. The instructor uses a black board and flip charts but the content is what’s important.

 

I photocopied the postulates, theorems, etc from the book so they could be right next to me. Before each lecture I reviewed each postulate, property, and theorem up to the point I had thus far reached in the course.

 

After working through these courses reading Euclid would be easier. In high school I don’t think I could have handled Euclid has my first exposure to geometry.

 

Possibly using software like the “The Geometer’s Sketchpad†( http://www.keypress.com/x24070.xml ) would be useful but I’m more into the logic and proofs of the course.
