Analytic Scoring Scale for Scoring Student Work on Problem-solving Tasks (by Jim Olsen) This is a rubric I designed (with initial help in a class) and have used with teachers for a number of years. The primary purpose of this scale is to award credit to students for following the 4-step problem-solving process. A student can get the wrong answer and still score quite well using this rubric. Conversely, a student with the right answer (alone) may not get all the points. If you wish to actually evaluate student knowledge of a specific math topic, I'd recommend using a different scale. This is a generalizable, analytic rubric. It does break up the student's work into parts (gives three sub-scores), but it is generalizable, in that it can be used with about any problem-solving problem.

Systematic Guess and Check Problem-Solving Strategy - The basics of trouble-shooting.

Amounts From Rates Worksheet - Primarily a graph interpretation activity. One of a number of, what I call, "early calculus topics." Real-world applications. Rates vary over time and the student must find the total amount accumulated. Appropriate for Algebra II or Pre-Calculus.

Solids of Revolution - Students rotate a triangular or rectangular region about an axis to create a solid. Students identify the solid and find its volume. Second "early calculus topic." Appropriate for Algebra II or Pre-Calculus. First 5 are straightforward cones and cylinders. Second 5 are a bit more challenging. No calculus required. Basic volume formulas used.

List of Objectives Involving Change, Rates, and Rate of Change - School districts need to decide where (when) students will be introduced to these ideas, and when the ideas will be developed, mastered, and reviewed.

Graphing Rational Functions by Hand - While generally I highly favor use of graphing technology, and favor real-world application, here's an activity that is only in a math context, and we get the answers just using our heads. It is strong in building number sense and function sense.

ICTM Handout from the presentation titled, "Using Problem Solving to Teach the Illinois Standards." Sarah Dalpiaz gave this talk (as I was out of town for a wedding).  In MSWord format.

Teaching Mathematics via problem solving: Here are some example problems.

Function Handouts

Here is a series of handouts related to the function concept. Each is given as a Word document and as a rich text format document. These handouts assume that students have been exposed to the function concept minimally. That is, they know that "there in an input, some thing happens, and there is an output," and that "inputs and outputs can be put into ordered pairs."

The Definition(s) of a Function ~ Is Yours in Here? Different books use different definitions for function. It's all the same concept. This handout helps make connections between different-sounding definitions. function-defs.doc function-defs.rtf

The Representation and Synonym Games - The fact that functions have many representations and that there are many synonyms for terms (such as "y-value") make it tough for students. This handout can help. REPS_SYN.doc REPS_SYN.rtf

Basic Function Objectives - Some of these basic objectives can be learned in middle school. basic_objectives.doc basic_objectives.rtf (For more advanced objectives see the Misconceptions and Difficulties handout below and reword the "difficulties" into things the student can do.)

Function Notation ~ "OK, so f(x) doesn't mean f times x, what does it mean?" FUN_NOTATON.doc FUN_NOTATON.rtf

Levels of Graph Comprehension - Although literal reading of data presented in graphical form is an important component of graph-reading ability, the maximum potential of the graph is realized when the reader is capable of interpreting and generalizing from the data. Just like reading text, there is difference between reading the words and comprehending the ideas. graphcomprehension.doc graphcomprehension.rtf (rich text format may not have all the graphics in the example)

Misconceptions and Difficulties in the Understanding the Function Concept - The function concept is central and key to mathematics, but it is also complex, due to its many related concepts and multiple representations. Miscon_difficulties.doc Miscon_difficulties.rtf

WolframAlphaWolframAlpha - "Computational knowledge engine" - Solves math problems, gives world statistics, stock prices--you name it!

AustralianHelp.com/Online-Tools - Many calculators which use WolframAlpha as the engine.

Wolfram (Mathematica) Demonstrations Project - This is a web collection of freely available, interactive demonstrations in math, science, and many other areas, at all levels from elementary education to front-line research. You do have to download the Mathematica Player, which is free, and runs all demonstrations. A few of my early favorites are Piecewise functions, Splitting a Cube, Buckyball in Icosahedron, Color (Rubic's) Cube, 3D Dissection Puzzle, Polygonal Numbers, and Fractal Tetrahedron. Fifteen Great Circles on a Sphere is awesome.

Protractor applet - Very nice. Has an intro (which can be skipped). Various interactive activities with and without a virtual protractor.

Lathe (creating 3D objects) applet - fun, get creative!

Contig is a very good strategy game (and you practice arithmetic and order of operations at the same time!). The site has the rules. I would play Contig first on a physical game board (with markers), to learn the game. Then learn how to do it on the computer (vs. the computer). There are different levels of difficulty and "computer strategy." This is timed (which can be adjusted). I believe the default settings are challenging and fast, so you probably want to change these the first time, or it will be frustrating.

Online - Interactive Mathematics - Online Practice (computer graded). Multiple levels.
