===Distance Activity===
====Activity Summary====
This activity is used to compute the distance between two computers.
Students can measure distances to evaluate intervals between two points in
school with the little green XO computer. Students organized in dyads should be placed
so that the sound emitted simultaneously by each of the computers can be levied
by the other so that the measured distance can be assessed.
With a combination of activities, it is possible that the students use
simultaneously and the Draw Distance.
====Affordances of the activity====
* Students can measure the length to go to get from one point to another.
* Students can measure the perimeter of the classroom.
* Students can measure the distance to make a course in Education
physical and sports (EPS) for example.
* Students may draw together and assess the distance between two drawings.
====Degree of centrality of the activity====
According to the curriculum of the fourth grade, the distance may be
Central to the main concepts of teaching / learning
characteristics to this grade level. The measured distances can then be
used to calculate an area where a surface for example. The concepts
distance measures have their place in mathematics, in the section of the
geometry.
Before the fourth year in Éveil 2nd year, and Draw Distance can be
combined and become central when spatio-temporal structure.
====Application pédagogique 1====
''Level of study'': 4th year
''Knowledge'': The perimeter and the half-perimeter of the rectangle
''Savoirfaire'':
Measure or calculate problems in situations on the perimeter and demipérimètre Rectangle
''History'':
Reading and analysis of statements of problems involving the calculation of perimeter and
half-perimeter of rectangular figures. (Eg the internal perimeter of the classroom to
using the XO).
Statement: Identify the lengths and widths of the class, and measure distances by means
of XO.
The teacher can arrange the class into dyads.
Two different dyads, each with an XO computer, identifies a length and a
width of the classroom, and carries through the measure of the distance. Each
side of the class is measured using the XO.
Both XO network engaged in the give a distance measure similar to a rule
calibrated accurately.
Students could then use these measurements to calculate the perimeter of the classroom.
Collaboration in dyads:
After displaying the remote computer screens, students share
viewing results and agree to the distance restraint.
====Application pédagogique 2====
''Level (s)'': 3rd grade of primary
''Knowledge'': Metric, straight line
''Savoirfaire'':
Measure and compare several segments of existing right
the environment in the home, in the classroom, in the schoolyard.
''History'':
Statement: Identify the distance measure, determine using the XO as provided by
the protocol to use. Compare distances obtained on the computer screen and
record the distances obtained in the Journal by naming them.
Application:
For example: the door of the class A, at the door of Class B: 10.11 meters.
Measurements in the schoolyard can be plotted on the plan
the school by pupils.
Collaboration in dyads:
Dyads distances are displayed on the screens of XO and agree to the
actual distance.
NB: Through this activity, teachers can help students develop skills to
measure distances with the XO.
====Pedagogical application 3====
''Level of study'': 2nd year of primary
''Knowledge": spatio-temporal structure: in front, behind, before, ... next to, far, near, around.
''Savoirfaire'':
Draw and / or identify an object in relation to another, or a student.
''History'':
Simulation of role play where one student gives orders to another student using the
terms: before, after, on ... near, far, after, for example around
====User Guide of the Distance====
As a first step, it will ensure that the XO is connected to the same network
meshed. To do this, see pages 8 and 9 of the Guide to the initiation and XO
Sugar environment V.8.2. In the Home view, begin the activity by clicking
the icon representing a dolphin.

In the box Share with: select my neighborhood. Follow one of
sharing procedures described on pages 16 and 17 of Getting Started in XO and
Sugar environment V.8.2. The two connected XO activity can begin. Click
Start far away.

It is therefore the position of XO computers one side to another. Computers emit
in turn a sound wave that can measure the distance between the two
screens. This will be displayed on the screen. Ideally, the XO should be placed on the
ground without any obstacles obstructing the sound emitted by the devices. Note that
weather can also influence the measure. Therefore
Atmosphere tab allows the student to enter the variables of temperature and humidity
on so that the measures are as accurate as possible.
