Zooming in on the Squares
Stage: 2 and 3
Start with a large square, join the midpoints of its sides, you'll see four right angled triangles. Remove these triangles, a second square is left. Repeat the operation. What happens?
Happy Numbers
Stage: 3 Challenge Level: 
Take any whole number between 1 and 999, add the squares of the digits to get a new number. Make some conjectures about what happens in general.
Approximating Pi
Stage: 4 and 5 Challenge Level:
By inscribing a circle in a square and then a square in a circle find an approximation to pi. By using a hexagon, can you improve on the approximation?
Litov's Mean Value Theorem
Stage: 3 Challenge Level:
Start with two numbers and generate a sequence where the next number is the mean of the last two numbers...
Summing Geometric Progressions
Stage: 4 and 5 Challenge Level:
Watch the video to see how to sum the sequence. Can you adapt the method to sum other sequences?
Continued Fractions I
Stage: 4 and 5
An article introducing continued fractions with some simple puzzles for the reader.
Archimedes and Numerical Roots
Stage: 4 Challenge Level:
