About: Online Math Games, Demonstration/Exploration Tools, and Puzzles


The purpose of this site is to collect high quality interactive applets which can be used by students and teachers to enhance student understanding of mathematics, and to organize them into a database web site so that they are easily accessible. The database of interactive applets, organized by grade level or high school math course, may be accessed by using the Index Page. I'm taking on this project because I hear frequently from K-12 classroom teachers that they would like to use Internet applets, but do not have the time to sift through the hundreds (1000's?) of mathematics web sites to mine the high quality interactive applets. None of the applets found in the index have been created by me. The applets are organized into three categories, Math Games, Demonstration/Exploration Tools, and Puzzles, which are defined on this page.

Like most web site projects, this is a work in progress and I'll add pages as I get time. Feedback, suggestions, and comments are welcome. A feedback form is below.

Basic Criteria

In general, for an interactive applet to be included in this database it needs to be:

Further selection criteria is given under the following three categories.

Math Games
~ For fun learning, indoor recess, incentives, after school programs, practice, at home use, etc. ~
Index Page

A Math Game is a learning activity which:

Demonstration/Exploration Tools 
~ For teacher demonstrations or student explorations ~
Index Page

A Demonstration/Exploration Tools is an applet which:

~ For those who like challenges and competition ~
Index Page

A Puzzle is an applet which:

Classroom Use Notes

Games, Demonstration/Exploration Tools, and Puzzles can be use as "Quickie Online Activities." For a description (and recommendations for using them) click What is a Quickie Online Activity?. On the Demonstration/Exploration Tools pages, on the far right-hand column of the table, Available Activities are given for many of the tools. They may be handouts, student recording sheets, or recommended questions.


The Content Standards are Number & Operations, Algebra, Geometry, Measurement, Probability & Statistics. See also, ISBE and NCTM.
The Process Standards are Problem Solving, Reasoning, Communication, Connections, Representation. See also, ISBE and NCTM.
