LET'S GO (Geometry & Origami ) Project activity samples

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 right-angled triangles and squares. Therefore, observing a single triangle the students could draw the squares formed from each side of the triangle.

Symmetry with origami ladybird and piano

We open fully our origami piano, ladybird
and look at them which geometric shapes appeared on the paper and draw it

Say Let's GO!

Hello dear partners and friends!
Your Turkish friends made a short film for you, we are sharing our feelings with you about our project, how we enjoy with our activities...
And Let's we say ''Let's GO!'' together!

Learning basic geometry concepts through paper folding II - Secondary School of Paranesti

Students of the Secondary School of Paranesti learn basic geometry concepts through paper folding. This is our second activity for the eTwinning project "Let's GO (Geometry & Origami)".

Activities:
1) Make a rectangle into a square without a ruler
2) Draw the square diagonal
3) Draw a triangle median
4) Make two triangles
5) Make a whale

 

Thanks for watching!

1 March - "Mărţişor"

Mărțișor is a Romanian celebration at the beginning of spring, on March the 1st in Romania, Moldova, and all territories inhabited by Romanians. Alike, though not identical customs can be found in Bulgaria (see Martenitsa), while similar ones exist in Albania and Italy.

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

(a-b)²=a²-2ab+b²

For such purpose we built two different figures using origami: a boat and a rooster

Christmas Origami Cards

The Romanian students received from their peers from Turkey Christmas cards.

It was a wonderful surprise.

Thank you very much, dear colleagues!

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

Students of the Ataturk Ortaokulu school learned exponential growth and decay through paper folding. Watch their video!

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

https://en.wikipedia.org/wiki/Geometry

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)
• Origamathematics
• Origami mathstyle
• Eurogami's maths club

Take part in the poll and choose your favourite title! Bear in mind that you can choose more than one title and that the poll will be open till Sunday 13 December 2015!
