Expanding Car park
A client wants to double the area of his car park.
He insists on retaining a square shape and as many of
the trees as possible.
• What is the best solution?
Why Choose This Problem?
• Interesting.
• Many approaches.
• Accessible.
• Layers.
• Linked to syllabus.
• Lends itself to group work and promotes
discussion.
• Requires students to explain their thinking.

Student Responses
Using GeoGebra (7)
Doing the Sierpinski Patterns
Group work, sharing opinions, collaborating (6)
Problem solving
Food (2)
Discovering new material
Divisibility Tests
Describe the part (or parts) of the project you
enjoyed most
Applying the skills outside of school
Creating worksheets for our class mates
Looking at maths in a different way
Presenting, (more time should be allowed)
The Puzzles
Residue Classes (simple and useful)
The presenting, the puzzles, the use of GeoGebra
Student Responses
Waking up on Saturday morning (2)
Nothing
Euler Line (2)
Solving very difficult algebra problems
Number theory
When it Ended
Describe the part (or parts) of the project you
enjoyed least
Having to miss a class due to my brother’s
confirmation
There wasn’t any part I didn’t enjoy
Having to present to my class mates
I Didn’t enjoy the modular arithmetic that much
Residue Classes-but I still enjoyed them
Presenting to the class (2)
GeoGebra (2)
Student Responses
Napoleon’s theorem, prime numbers, Circumcentre etc.
How to work out problems to the full extent
To read the question carefully
I learned how to use algebra to prove things
My problem-solving improved as a result
How GeoGebra works and just thinking about numbers
Not to overreact when faced with a problem but to take my time
and figure it out
What did you learn most as a result of participating in the project
That with determination and hard work along with group work
you can solve problems easily
Have a better understanding of Maths
It’s not about the answer it’s the approach you adopt
How to approach problems
It’s not about the end answer (sic) it’s about trying to figure it
out.
There are different ways of looking at maths
There are multiple ways of looking at problems
To approach questions differently and to figure out how I got
the answer before writing down the answer
If you want to do well at maths you have to work at it
Would you like to see the approach used in the project being more
widely used in mathematics lessons in schools
