ShodorGraphing Calculators

[Back]

 
Graphit THE ORIGINAL!  Students can graph functions and sets of ordered pairs on the same coordinate plane -- similar to a graphing calculator.
Scatter Plot Similar to Simple Plot allowing the user to graph ordered pairs but also gives the ability to label x- and y- axes thus making the activity more appropriate for data sets and the resulting scatter plot.
Slope Slider This activity allows the manipulation of a linear function of the form f(x)=mx+b and encourages the user to explore the relationship between slope and intercept in the cartesian coordinate system.
Function Flyer A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.

Enter a quadratic function like  2*x^2+3*x-4  and play with the sliders!

Data Flyer Similar to Function Flyer, but with the capability of plotting data points as well as a function. Then you can tweak the function to fit the data.
