ACTIVITY 1 - PI TANGRAM (CRO)
The goal of the game is to combine tangram in three forms:
1. Number π
2. Square
3. An isosceles right triangle.
You can play in Geogebra or print a template

(I have made new folder in our common GeoGebra book - Pi day.
You can copy the activities and put them in the same folder to keep all the work in one place.)
ACTIVITIES 2 – PI ART (CRO)
Martin Krzywinski is a scientist who specializes in bioinformatics, or using computer science and statistics to understand biological data. Krzywinski started publishing his pi art in 2013, beginning with this visualization.
Each digit of pi is represented by a dot of a different color: 3 is orange, 1 is red, 4 is yellow, and so on. Krzywinski then folded these colored dots, each of which represents a different digit ("1" or "4"), into a spiral.
Create your own color code and create a pi-dot image in GeoGebra or on paper.

ACTIVITY 3 - PI SKYSCRAPER (CRO)
Instructions:
The goal is to draw the outline of the PI city by drawing columns on paper ori n GeoGebra. The height of each column should correspond to the decimal number π.
π = 3.141592653589793238462643383279 5028841971693993751058209749445…
In GeoGebra we can also specify a color code - for each digit one color

ACTIVITY 4 - IN WHAT BOX IS THE MOST PITE? (CRO)
Instructions:
Three boxes contain pies. All pies are equal in height.
Calculate and explain which box contains the most pies.
Try to design your task and draw it on paper or in Geogebra.

ACITIVITY 5 - PI SNAKES (GER)
"PI snakes" can easily be created with regular squares (easier in a coordinate system that is hided at the end - a little more demanding without using it).
ACTIVITY 6 – EINSTEIN'S RIDDLE (CRO)
Albert Einstein's birthday is on March 14, which also happens to be Pi Day.
The legend says that this problem was created by Albert Einstein in the last century. Einstein said that only 2% of the world could solve it.
Use all the clues below to fill the grid and answer the question: "Who owns the fish?"
