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)
- Albert's machine
- Graphic representations (2)
- Affine functions
- Linear functions
Graphic representations (1):
Goals :
- Visualize the graphic representation of a phenomenon
- Read, use a graphical representation
Albert's machine:
Goals :
- Introduce the notion of function
- Introduce function notations and vocabulary
Graphic representations (2):
Goals :
- Search, extract information
- Read, interpret a graphical representation
Affine functions:
Goals :
- Recognize an affine function
- Plot the graphical representation of an affine function
- Determine the coefficients of an affine function
Linear 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 percentages
II. TRAINING EXERCISES
Eight 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 function
Each exercise is configurable (number of questions, difficulty), and includes a correction in case of error.
III. LESSONS AND TOOLS
Three modules are available:
- Lesson
- Curve plotter
- Table of values
The 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. PROBLEMS
Four problems are available:
- Rectangle of maximum area
- Coming soon
- Coming soon
- Coming soon
Rectangle of maximum area allows to study the variations of the area of a rectangle of constant perimeter, and to find the maximum graphically.
