Course / Level 1 st ESO
1. Learning outcomes / Evaluation criteria
To Draw notable points in a triangle like Ortocenter, Incenter,
baricenter,circuncenter
To Draw geometric places like bisector and perpendicular bisector
2. Subject Content Triangle notable points like Ortocenter, Incenter, baricenter,circuncenter, bisector and perpendicular bisector
3. Language Content / Communication
Vocabulary Tiangle,
Ortocenter,
Incenter,
Baricenter,
Circuncenter,
Bisector,
Perpendicular bisector
Structures Create definitios, the use of let.....be
Algoritms
Discourse type Explain how to do somthing
Language skills Create definitions from a picture, explain an algoritm.
Present simple:
a bisector is a line whose divide an angle in two equal angles
we can draw a bisector using ......
Imperative
To make a bisector, draw an arc from .....
To find the ciscuncenter, draw the lines from the edge
to ...
Context This concepts will be introduced using the triangulation position. It
is used in GPS tecnologies by all mobile devices.
Congnitive process The students will know and understand this conceptsand they will apply them in unreal surmise.
Activities work and Final
The activities will be:
• Activities of join concepts and definitions.
• Explain how to draw a notable point. (speaking and wriiting activities)
• Draw the notable points in diferent types of triangles using paper, pencil and rules, and using GeoGebra (TIC).
The final work will be take 3 pieces of string (5m aprox.
each one) with groups of 4 students (3, one for each edge
of the triangle and 1 will be on the position of one notable
point), take a photo. And then, usong the Geogebra make
the proof is is correct the position of the “central” student.
Metodology
Resouces: We can use manipulative resouces in order to explain
how to find the notable points, The exposition ca be seen using
these videos.

Basic Competencies
TIC usage, relation with the real wold, Fine arts and arquitecture
competencies (using strings), writing and reading
Evaluation
In addition of the activities, whitch the students will have done, an
evaluation proof will be take place to know if they have understand
the knowlage of this unit
