a fret for our square

laboratory developed in 3a primary
Objective: to know translate from notation geometric analytics to and viceversa
the fact: one new letter from the bugs of the forest.
Our knowing miniums are become to you famous in the world of the bugs for the public square that they have (!) realized [you see laboratory a public square in the forest] and, to force of festeggiamenti, they are perhaps little mounting the head.
The Fly, coming back from a flight over a great public square in a city that slide0411_image003 in the water, has seen of the designs made on the pavement.
Therefore, to table to lunch with the other friends bugs (but always to a sure distance from ragnetto) Fly if `it has come outside with a esclamazione: it wants a pavement to us for our public square!
Uproarious applauses. , Then unexpected Hush
Vocina from the bottom that says: good! It explains like is made to us!
The fly, little a little surprised offense and, us ings a po around `, then it proposes it is drunk a toast and it said: of it we speak at dinner!
Later, at dinner…
Moscow is due to remove a moment and its news is not had more.
To the cricket nothing does not come in mind.
Perhaps ragnetto the test to propose the design to ragnatela, but comes hissed from someone in bottom (Moscow enters something there here)
the cicala speaks about one its cousins of Ravenna, than slide0411_image005scorsa the summer, in the warmest day, it has it capacity to refresh itself in a full place of designs made with sure pietruzze and small and squared pieces of glass that the tourists called mosaic.
It had seen a design made to narrow lanes and it had walked to us over, just well. It was on a arco that it arrived until the ceiling and then returned down. It was just beautiful.
General applause for the cicala and, of course, more job for us.
Because our friends send to say to us: how we realize this beautiful thing? We don’t  know the secret formula for the shapeslide0411_image005

 

 

 

Later, to supper…
Fly is due to remove a moment and its news is not had more.

Ah, there is another small, very little problem.
In the yard of the public square the ants are working. They are best constructors but they do not know how to read the designs. They communicate being transmitted of the codes for the movements, in similar to  the small robots are commant. (ahead two steps, turn to right, it turns on the left) with the antennas, and therefore we would have to communicate they therefore the design…
ehm. Have a nice job

slide0420_image019A glance to the design

the issues:
1. To understand as it is made design
2. To find a way to transmit to the design to the ants
draft of I interlace myself of Greeks made from bizantini, that they were a little Greek little roman one. Prince of name Galla Placidia is dedicated to one.
We can read the tracings like opened distances, except one (green one) that it closes of the squares.
How to make?
The main problem is: how we will be able to communicate the ants?
We have need of one small digressione on the topic of the communication between bugs
As the ants communicate: messages transmitted with scariche small electrical workers. Example of as and which information are passed. (possible developments: tried to communicate something as they would make the ants)
Between They make therefore in order to trace the figures: one says to the other: ahead 5 steps, then, turn to right or turn ahead on the left and 3 steps and therefore via…
We can indicate it in short way therefore:

Ahead 5 steps AV 5
turn on the left SI
turn to right DE

  1. image038the Design of the Greek comes projected on the wall of the classroom One student translate and writes or dictates to the distance in notation ant. If the translation contains some small error, also holds it.(verification). A team of tracciatori test to construct the distance to earth, on the pavement. The square is composed from a reader, a cursore (moves and turns the triangolino that she just marks to the running position) and a true tracciatore and that, with adhesive tape of the color of the trace, follows and marks the distance of the cursore.
    To fine tracciamento we confront the design formed with that one projected. They are equal? If yes, we continue. Otherwise, we try to characterize the errors. The instructions are right? Draft of an execution error? Based on the type of characterized error, we see to supply to the correction.
    It comes delivered to every student a sheet, A3 format that round contains a rappresentazione of tiles of the pavement and a space. On the sheet they are also marks points to you of beginning of tracings with the same colors used on the blackboard and to earth.
    We decide the beginning point and we begin to write the code for the design

Returns to our main traced complicated one. Of it we extract one first sequence, while we see the trace projected. proviamo to define of together the code.

Once defined the code, we try to make to realize it on the pavement, with one square to three: the reader, the robot, the tracciatore

Appraisal: it is to place? In the same way that in the previous experience, errors of transcription or execution are important. The verification becomes effective moment of acknowledgment and correction of the code.

The image of the mosaic projected on the wall has been at last occasion of argument in order to try images, suggestions, simmetrie, that they could emerge from the figure.
someone has perceived the regolarities of a modular grill on which the mosaic could be arranged.

on the student

Every sheet it then repeats the experience on the sheet that it has received. The situation is similar to the two previous ones, unless for some aspects:
the scale, obviously, that it allows to make to accommodate a “pavement” in a paper sheet.
the possibility to expand the design beyond the space physically limited from benches and walls. to trace beyond the wall, under the benches. The classroom pavement is marked on the sheet in thinner various feature and it extends to a measure that for the student would be unattainable.
The operation comes repeated on the sheet that allows to rewrite the tracings,
Then to everyone comes delivered the codes that can be used in order to trace the own Greeks

the design come repeated on the sheet that everyone has on hand leaving from the segnalini present on the designed grill.
It can be useful to leave the boys free to orient the sheet watching it and ruotandolo from the point of view of the tracciatore (= the ant). A cue for the issue of the absolute and relative reference.
