Third use 
At the end of basic school you will be able to start using this more complex calculator, which also performs operations whose meaning you will discover in future years. 
K
graph paper A "sheet" of graph paper to build (by hand) graphs of "experimental" functions (such as the weight of a person over the years) or functions expressed by formulas. 
drawing (1) How is a drawing done with a computer? A simple program to get an idea of how it's done. 
drawing (2) How to draw on squared paper using the computer 
drawing (3) old version How to draw on squared paper using the computer (bis) 
drawing (4) old version How to draw (using the computer) on squared paper /paper without squares (for the teacher) drawing (4b) on larger paper 
drawing (5) old version How to draw (using the computer) on squared paper /paper without squares (for the teacher)  larger size 
Polyomino 
Treasure Island Indicate the steps (in the N,S,W,E directions) to reach the treasure. 
L
percentages (with our calculator I would do: 20/160*100 = 12.5) 
M
circle divided into cents and semicircle divided into fiftieths (to construct areograms) 
N
sums and ratios (I can enter the numbers directly or increase or decrease the value of A or B by 1) 
O
sorting (and median)  
How to order 
Of course, like the other scripts, this is useful for proposing to the pupils activities they can practice on their own, and check the answers without the intervention of the teacher! 
In addition to the median (32), there are also the datum that delimits the first quarter of data (27) and the datum that delimits the first 3 quarters of data (38), and their difference (11), i.e. the width of the interval where the middle half of the data is. 
ordering of words
written in lowercase characters, separated by commas.
P mean 

The mean is an "average value" other than the median. A couple of examples. The average of the heights of two people is the value that is halfway between them. The average milk consumption of family members is the sum of individual consumption divided by the number of members. You will see in future years the usefulness of the comparison between mean and median. 
Q
fractions simplifying fractions 

Fractional calculus 

R divisors 
S prime factorization 
T sum angles of triangle  
It is easy to deduce that the sum of the angles of a triangle is a flat angle: moving along the sides, I return to the initial position by making half a turn, that is, rotating by 180°  
angles / sides / area of a triangle  
It is possible to explore the links between the measurements of the sides and angles of a triangle, explore their link with the area of it, and conjecture the theorem proved below. 
U
Pythagoras Theorem The previous figures recall cases in which 3 angles or sides are enough to know the other dimensions of a triangle. A special case is that in which an angle is right: given two sides I can easily find the third. 
V the measurements are approximate  
As^{ }we recalled in point H, in practice there are not many figures with which we can know a quantity, especially if we "measure it". 
W parables (and lines)  
In addition to making calculations, formulas are also used to describe figures, such as lines and parables. With this script I can easily draw both lines and parabolas, after having learned to draw them by hand (for the lines reduce "a" until it is equal to 0).  
hyperbolas (functions with hyperbolic graph, even without calling it that)  
Our class goes to visit a museum. The price for schools is €10 plus €1 for each pupil. What is the graph of individual spending as the number of participants varies, from 1 to 20? If the price were €5 plus €2 per pupil, up to what number of pupils would this second rate be worth it? 
X circles  
In a similar plane, with coordinates, I can draw circles. I can change the position of the center and change the radius.  
hyperbolas (even for negative x) 
Y area, perimeter, center  
Perimeter and area of a polygon: 
Z histograms (starting from single data)  
We have seen in B how to draw simple histograms. Suppose we have a sequence of unclassified data, such as the following measurements (in cm) of the lengths of a certain number of beans, measured by 12yearold pupils. With this script we can choose an interval in which there are data and divide it into many intervals, in order to represent how the data is distributed in these intervals. Right what we can get.
