level, but I CAN rate "coolness"
Fraction Concepts
http://mathforum.org/mathtools/lesson/20064/
This is really nice. It's late now, but I want to have my 9yearold
son try it out tomorrow. I think it is very well done!
 Perimeter and Area
http://mathforum.org/mathtools/lesson/20068/
Interesting; I could see this as one of the ways to reach certain types of
learners in a classroom (others might use handson manipulatives, etc.)
 Geometric Transformations
http://mathforum.org/mathtools/lesson/20072/
In "Introduction," applets don't work in activities 7 and 9 (these appear to
be nonNLVM applet links). A quick perusal of the rest of the lesson reveals
a welldesigned lesson with meaningful, higherorder thinking involved. If
I were teaching Geometry this coming year, I'd use it for sure; I'll certainly
suggest it to a colleague (perhaps for review, or independent practice... we
just worked up a transformations unit we were proud of!).
 Writing Equations of Lines
http://mathforum.org/mathtools/lesson/20074/
This is probably better as a review than as introduction (which is fine!).
Some of the builtin checking didn't work as anticipated... I typed 2.5x +
16.5, which was marked incorrect, with the "correct" answer given as (5/2)x +
(33/2). NOT a big deal. I will probably put links to this on my course web
site for students to use as review in my Algebra 2 course (many won't need the
reviewI hope!).
 Integer Arithmetic
http://mathforum.org/mathtools/lesson/20070/
I didn't care for the temperature multiplication model; I found it confusing
(which number is supposed to be negative? I had to use what I knew the answer
was to be to figure out how the model worked...). I had similar trouble with
"Number Line Bars" (activity 5 on integer multiplication). Instructions for
activity 6 on integer multiplication should have PC users press "Alt," not
"Ctrl."
 Patterns, Relations, and Functions
http://mathforum.org/mathtools/lesson/20094/
Very nice. What was student feedback like? I think some students might
have become bored with it, even though it does become more complex as you work
through it...
 Working with Place Value
http://mathforum.org/mathtools/lesson/20090/
Outside my comfort zone.
 Right Triangle Geometry
http://mathforum.org/mathtools/lesson/20071/
I like the applet this lesson uses! I think the lesson could use more
development (though it is reasonable as a review).
 Transformations of Functions
http://mathforum.org/mathtools/lesson/20096/
Very nice. I anticipate using this one, again probably as an independent
review activity for some students, in Algebra 2 this year.
