Slide 5 - Tekstslide
Build a paper tower
Work as a team to build a paper tower which can
stand for 30s without anything holding it up.
You may hold it up until the timer starts.

Computational Thinking
Slide 9 - Tekstslide
1 Decomposition
Break your problems down into more manageable chunks
Find the sum of all the numbers between 1 and 200
Slide 10 - Tekstslide
2 Pattern Recognition
What can you observe and learn from?
Find the sum of all the numbers between 1 and 200
1+200 = 201
2+199 = 201
Slide 11 - Tekstslide
3 Abstraction
Identify similarities and differences in similar problems.
Find the sum of all the numbers between 1 and 200
1+200 = 201 200/2 = 100 pairs
2+199 = 201
Slide 12 - Tekstslide
4 Algorithm design
Develop step-by-step instructions to solve this and similar problems.
Find the sum of all the numbers between 1 and 200
(1+200) * (200/2) = 20100
Step 1...

Slide 15 - Open vraag
What can be improved about your design?
Slide 16 - Open vraag
Plan with your team
Using everything you've learned, plan with your team to build another paper tower.
Slide 17 - Tekstslide
Build a paper tower again
Using what you've learned, work as a team to build a paper tower which can stand for 30s without anything holding it up.
You may hold it up until the timer starts.
