Algebra

- Desmos - great free online graphing calculator that runs on virtually all devices.

*Desmos and GeoGebra are two of the best math programs on the Internet.*Runs in the browser or can be downloaded for free. - Spotting Numbers and Visual Patterns (two different sites) - great for making the trifecta-connection between number patterns, geometry, and algebra.
- Line of Best Fit - regression process. See also Best-fit with a Visual Mode: Measuring Error.

Number and Reasoning

- Broken Calculator - Problem solving. The dimmed buttons on the calculator are broken (they don't work!). Your goal is to use the buttons that do work to compute the numbers from 1 through 15 or other target numbers.
- Fraction Model - Models fractions and mixed numbers with set, area, and length models (NCTM Illuminations).
- Coin Problem - Find the counterfeit coin. Four levels of play.
- Percent of a number Fill in any two of the three numbers in _% of __ is __. (Virtual Manipulative)
- Powers of Ten - View the Milky Way at 10 million light years from the Earth.

Geometry

- GeoGebra - - "Dynamic Mathematics for Everyone" - does geometry and algebra.
- Building Houses - 3D visualization.
- Point of View Game - 3D visualization. Has multiple levels.
- Isometric Drawing Tool - Create dynamic drawings on isometric dot paper. View in 2-D or 3-D.
- Platonic
Solids and Platonic
Solid Duals - Investigate the solids (cube, tetrahedron,
...). Rotate the shape.
the edges, vertices, and the faces to color (and count them). V - E + F = ? (Virtual Manipulative)**Shift-click** - Pythagorean Theorem - Visual (geometric) demonstrations of the Pythagorean Theorem. (more apps)
- Cyberchase Airlines Builder Game - Drag (and sometime rotate) segments to make a spaceship. A spaceship must be an enclosed shape. Fixed perimeter. Find the shapes.
- Cut-outs, Nets - This applet folds a 2D net into a 3D object. Click and drag to manipulate the object/net.
- Poly - a shareware program for exploring and constructing polyhedra from nets.

Measurement

- Protractor applet - Very nice. Various interactive activities with and without a virtual protractor.
- Understanding Distance, Speed, and Time Relationships - explore slope and starting points.
- Learning about Rate of Change in Linear Functions Using Interactive Graphs see also Changing Cost per Minute

Probability

- Spinners - Can make various spinners with equal or unequal regions. Spin once or multiple times. Results table provided.
- Ball-Dropping applet - probability and Pascal's Triangle.

Data Analysis

- Create a Graph Tool - for students (others) to make statistical graphs (NCES).
- Plop It! - Tool for demonstrating how mean, median, and mode change. (Shodor)
- Mean and Median - Tool (from NCTM) to show how mean and median change. Also shows the box plot.

Trigonometry & Pre-Calculus

- GeoGebra - - "Dynamic Mathematics for Everyone" - does geometry and algebra.
- Six Trig Functions - Manipulate the angle and see the results.
- Conic Flyer - Manipulate h, k, r, etc. in the equation and see the resulting effects on the graph.

Calculus

- Secant Line and Tangent Line - for calculus - the classic, fix a point on the curve, move another point on the curve to form a tangent....
- Surfing Derivatives - demonstrated how tangent line changes as a point (surfer) moves along y=f(x).
- Piecewise Functions, Limits, and Continuity - does left-hand, right-hand, and 2-sided limit.

- Cyberchase (PBS) Games - Click here for my descriptions and my evaluation of the games.
- National Center for Education Statistics (NCES).

- Geogebra - "Dynamic Mathematics for Everyone" - does geometry and algebra.
*Best math program on the Internet (and it's free).*This is a fully-developed, multi-feature program. Easy to learn. Here is a handout I prepared to help get started. - Desmos - Best free online graphing calculator. This is explicitly designed as an education tool. Great Classroom Activities (teacher) area too.
- Wolfram Alpha - "Computational Knowledge Engine"
*very*powerful. Watch out! It will do math homework! Created by Wolfram Research (who make Mathematica). Introduction video by Steven Wolfram. See, also Wolfram Alpha's first cousin Wolfram Demonstrations Project.

- One computer and large display for class demonstrations.
- Document camera (Elmo, etc.). Also, iPad can be used as a document camera using
*Justand V2*. - Portable iPad lab - wheel the cabinet to the classroom and use the iPad there. (Personal opinion: I've had better luck with iPads than laptops.)
- Computer lab - one student (or two students) per computer.
- 3-4 computers in the classroom for students to do
*Quickie Online Activities*. - Interactive whiteboard (SmartBoard or other manufacturer)
- Interactive Quizzes - students use SmartPhones/iPads/devices to respond to questions on the screen (big one or their own). (e.g., quizizz.com)

('8.' See the next list for ways to use a computer to do all the other things a teacher has to do...)
