Features Labo des Fonctions

The Functions Lab is a companion application for teaching functions in cycle 4.
Most of the tools can also be used in second.It comprises four main parts:I.
ACTIVITIES Five activities are available:- Graphic representations (1)- Alberts machine- Graphic representations (2)- Affine functions- Linear functionsGraphic representations (1):Goals :- Visualize the graphic representation of a phenomenon- Read, use a graphical representationAlberts machine:Goals :- Introduce the notion of function- Introduce function notations and vocabularyGraphic representations (2):Goals :- Search, extract information- Read, interpret a graphical representationAffine functions:Goals :- Recognize an affine function- Plot the graphical representation of an affine function- Determine the coefficients of an affine functionLinear functions:Goals :- Recognize a linear function- Plot the graphical representation of a linear function- Determine the leading coefficient of a linear function- Associating linear function and situation of proportionality- Associating linear function and percentagesII.
TRAINING EXERCISESEight exercises are available:- Vocabulary- Tables of values ​​and ratings- Image and background calculations- Calculation programs- Reading of images and antecedents- Tables of values ​​and curves- Curves, notations and vocabulary- Represent an affine functionEach exercise is configurable (number of questions, difficulty), and includes a correction in case of error.III.
LESSONS AND TOOLSThree modules are available:- Lesson- Curve plotter- Table of valuesThe lesson is that of the college program: Notion of function, affine functions and linear functions.Curve plotter allows you to plot up to 3 graphic representations in the same reference.Table of values ​​allows you to obtain...
the table of values ​​of any function (10 values ​​with the smallest value and the step to choose), and to visualize the points (and possibly the curve) in an orthogonal reference .IV.
PROBLEMSFour problems are available:- Rectangle of maximum area- Coming soon- Coming soon- Coming soonRectangle of maximum area allows to study the variations of the area of ​​a rectangle of constant perimeter, and to find the maximum graphically.
