COLLEGE CHRISTINE DE
PISAN Lesson Plan Template 2016
1. ACTIVITY INFORMATION


Subject/Course: Geometry

Name: All pupils of the class 5°1
Teacher: Armelle Mandaroux

Grade Level: 6 ^{th}

Topic: Axis of symmetry of geometrical figures

Length of Period: 1 lesson

2.
Expectations or Goals

Pupils
will be able to understand what an axis of symmetry is and will know the axis
of symmetry of some usual geometrical figures.

3.
Content

A
square has four axis of symmetry: its diagonals and the midperpendiculars of
its sides.
A
rectangle has two axis of symmetry: the midperpendiculars of its sides.
A disk has an infinity of axis of symmetry. An equilateral triangle has three axis of symmetry: the midperpendiculars of its sides. A rhombus has two axis of symmetry: its diagonals. 
4.Description
of Activity

Give to the pupils origami papers,
pencil, ruler, scissors, protractor, compass.
Ask pupils to list the usual
geometrical figures they know then to draw them.
Explain them what an axis of symmetry
is and ask them to fold their geometrical figures to find the axis of symmetry.

Platonic solids
We have built the platonic solids through modular origami. Here you can see several pictures of the constructions before and after assembling them.
Thales & Pithagoras theorem
We have developed different activities in order to explain two of the most important theorems in geometry.
Thales' theorem.
The students deduced the Thales' theorem through paper folding. They made different foldings. We could take advantage of the activity to explain concepts like staight lines, points, segments and parallel lines.
Pythagoras' theorem
We used an easy and common Origami construction (a boat) to explain the Pythagoras' theorem. After unfolding the boat we can find out different rightangled triangles and squares. Therefore, observing a single triangle the students could draw the squares formed from each side of the triangle.

1 March  "Mărţişor"
The name Mărțișor is the diminutive of marț, the old folk name for March (Martie, in modern Romanian), and thus literally means "little March". It is also the folk name for this month.
Mărțișor is names for the red and white string from which a small decoration is tied, and which is offered by people on the 1st day of March. Giving this talisman to people is an old custom, and it is believed that the one who wears the red and white string will be strong and healthy for the year to come. It is also a symbol of the coming spring.
A very popular symbol in relation to Martisor is the snowdrop flower, which is also considered in Romania symbol for spring time.

Introduction
Two spanish students have decided to introduce their school and welcome every body involved in the project.
Algebraic Identities with origami
In Spain, we carried out an activity to explain the demonstration of two important algebraic identities:
(a+b)²=a²+2ab+b²
(ab)²=a²2ab+b²
For such purpose we built two different figures using origami: a boat and a rooster

Learning basic geometry concepts through paper folding  Secondary School of Paranesti
Students of the Secondary School of Paranesti learn basic geometry concepts through paper folding.
Questions asked:
1) When two lines intersect how many points do they have in common?
2) When two lines intersect how many angles are formed?
3) What is the relationship of these angles?

Learning exponential functions through paper folding  Ataturk Ortaokulu

How many times would you have to fold a piece of paper to reach the moon?
This video introduces students to the concept of exponential growth. By seeing what happens when folding just one piece of paper, we see the unbelievable potential of exponential growth. So, the question of the video is: how many times would you have to fold a piece of paper to reach the moon?

1st activity  Basic geometry concepts & paper folding
The first activity of our project is about basic geometric concepts. We will define plane, point, particular plane, point, ray, line, and line segment.
But, before saying more about our activity, do you know who is the person in the painting? Also, do you know what "geometry" means?
If you do not, then perhaps you should read the following pages in Wikipedia:
https://en.wikipedia.org/wiki/Euclid
Now, can you answer the questions above? Leave your answer as a comment in this post!

And the title of the project is... See the results of the poll!
Choosing the best title for a project is hard. That's why all partner classes discussed and brainstormed ideas about the title of the project.We collected the best ideas and organised a poll to select the most suitable one for our project. In total, 64 students and teachers took part in the poll and most of them selected "Let's GO! (Geometry & Origami)" for the title of the project. See in the screenshot below the results in detail:
Thank you all for your participation in this poll!
So, from this day we apply the title "Let's GO! (Geometry & Origami)" to the blog replacing the old one "Origami & Maths". Also, we change the URL of the blog from "http://mathematicalorigami.blogspot.com/" to "http://letsgeometryorigami.blogspot.com".
We are looking forward for further activities!

Vote for your favourite project title!
Our project on maths and origami is about to start, but we still miss a title for it! Students from Turkey, Greece, Spain, and Romania brainstormed ideas for the project title and a poll has been created to select the most favourite one! The poll is located in the sidebar. In total, there are five choices:
 Let's GO! (Geometry & Origami)
 Let's GO together! (Geometry & Origami)
