I am going to be presenting at a technology in conference next weekend, February 21, 2015. The topic is integrating iPad apps into the classroom, your lesson plans while meeting state standards. After playing with Lion Grapher in the classroom, I know know the sequential use of the four modes will allow students to learn more about sloping and graphing.
Line mode would be first so they can move a line (y = -1x + 0) up, down, left or right to explore what happens to the y-intercept as the line moves. In addition, you can change the slope and sign for further exploration.
Point mode lets students put in two points and the app will map the portion of the line lying between the two points and it will provide the m part of the y=mx + b. This is a good way for students to check their math when they calculate slope by hand.
Intercept mode has the student input a point and the y intercept. It graphs the full line and shows the equation. This is a nice way for students to check their work after they've used the point slope form.
Lion Mode is great for calculating the slope off the graph because the student has to figure out the slope from the y intercept to the lion's head by counting square on the graph. This helps students develop a connection from the visual picture for the slope and the mathematical m.
The order I would do this in would be, Line mode, Lion mode, point mode and intercept mode. I like this app a lot but my kids don't like it only because they find it difficult to use the app at first. Once they have the hang of using it, they like it.

Lion Grapher
Lion Grapher is another app from the center for algebraic thought. It has four modes which make it possible to use this app in a couple different classes and over any unit dealing with finding the equation of a line.
The first mode is the lion mode. In this mode, the student finds the slope to put the line through thd lions head. The student is going to use the origin as one point and the location of the lions head as the other point. If the student is successful, they get points. If they are incorrect, they lose 25 points each time.
Next is the Intercept mode where the student uses a point and the y intercept to find the line.then the student can use 2points for the app to find the equation of a line. Finally is the line mode which allows a student to play with the graph of a line by moving it up, down, left, or right.
I like that this app has students exploring the slope from a point on the graph, two points, or the equation of a line from two points, or a point and the slope. I find that my ELL students really do much better when they have the opportunity to explore in addition to videos and lectures. I had fun exploring the app myself.
This is a nice app and its free
