| 8 | Action Grapher Algebra | Three apps in one! Students often have difficulty understanding the relationship between axes in a graph and how the two variables interact. They tend to believe the graph will look like reality. To develop a more comprehensive understanding of the dynamic taking place in graphs, each of these apps challenge the student to explore how the information from each axis influences the graph. In Bicycle, the user takes a bike on a journey up and down a hill and sees different graphical representations of what is going on based on considering different variables. In Flask, the user draws a flask of any shape, watches it fill up with water, and sees how the graph is influenced by the shape of the flask.In Doodle Pad the user can draw an action and instantly watch two distinct graphs appear, demonstrating different representations of what is happening mathematically. | -- | Free | View in iTunes |

| 11 | Graphing in Groups | In Graphing in Groups, students work alone or in pairs to construct graphs of linear functions by using their respective iOS devices to move points in a shared Cartesian window. The Graphing in Groups NetLogo Hubnet model allows a teacher to view and display the graphing windows for all student pairs. Two pairs, one yellow and one green, can form lines in each graphing window. As students move their points in their respective graphing windows, they can mark select locations to form lines, the y=mx+b equation for which is displayed above or below the graph. This configuration allows students to participate in a variety of structured or open-ended collaborative mathematics tasks involving generating lines with particular properties—a specific slope or intercept, a parallel or perpendicular relationship to another group’s line, passage through a select point, and so on. With the Graphing in Groups application students can - give their point a custom name - use arrow keys to move their point on a Cartesian graph - draw lines between their point and a second point - learn about y=mx+b, by observing the effect of point movement on the equation - use the built-in camera or photo library to generate graphing background images - change the scale of their graphs - work individually, using a second point to construct their own lines - work collaboratively, seeing their partner's point, creating lines together - send photos and graphing commands to the teacher's computer, for the whole class to see Detailed instructions for using Graphing In Groups can be found on the website. | -- | Free | View in iTunes |
| 12 | Free Graphing Calculator | *** Now over 4 million downloads. Thanks users!*** A powerful, flexible graphing calculator . . . and it's free! Does far more than most of the paid calculators out there . . . let alone the free ones. Features: 1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following: • the usual arithmetic functions and exponentiation. • square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction. 2) Graphing. Capabilities: • Graph up to four equations at once. • Graphs are labeled. • You can drag the graph or pinch to zoom in or out. • Calculator can find roots and intersections. • Graph in polar coordinates. • Graph parametric equations • Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this! 3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework! 4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework! 5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row. 6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition. 7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics. 8) Keep track of significant figures [AKA sig figs] 9) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line. If you are viewing this in iTunes, you will see five iPhone screenshots and five iPad screenshots. But even ten shots don't come close to showing everything this calculator can do. I'd love to hear your comments or suggestions. You can write me at mathscixyzgraphcalc@gmail.com -- but without the xyz. Thanks! | -- | Free | View in iTunes |

| 15 | Linear Model | From research we know that students have difficulty understanding multiple representations of the same information. This app allows students to explore how changes in the formula or graph or table will impact the other two. Another nice feature of the graph is the ability to watch how a change in the scale will not change the formula or table but will change the graph appearance. The app allows you to enter a linear equation to be displayed on the graph, but you can also use the dots on the line to move it around yourself. You can also choose a different starting point for x in the table. Linear Model supports equations in both slope intercept, y = mx + b, and standard form, Ax + By = C formats.
