How many sweets in the jar?


“Guess how many sweets are in the jar” is a fundraising game. A large see-through jar is filled with a carefully counted number of sweets. People then try to guess how many sweets are in the jar. Each contestant has

Pascal Triangle


In mathematics, one of the most interesting number patterns is Pascal’s Triangle. It is named after Blaise Pascal (1623 – 1662), a famous French Mathematician and Philosopher. To build a Pascal Triangle we start with a “1” at the top.

Infinite Quarter Series


The infinite quarter series is a series where each term is a quarter of the previous one: We can visually represent this series by dividing a canvas (or price of paper) into 4 quadrants and colouring in one quadrant (bottom

Euler’s Number

Golden Angle


In geometry, the golden angle is the smaller of the two angles created by sectioning the circumference of a circle according to the golden ratio. Golden Angle ≈ 137.5° The golden angle plays a significant role in the theory of

Graphing Algorithm


In this challenge we will write several procedures to graph different mathematical equations on screen using Python Turtle. We will focus on: Linear equations: y = ax + b Quadratic equations: y = ax2 + bx + c Trigonometric functions:

3D Staircase Challenge


In this challenge you will use http://www.beetleblocks.com/ to create some 3D models to represent different types of staircases. I will use iteration (for loops) to make your code more effective and investigate the use of (x,y,z) coordinates to create your

Factorial Challenge


In Mathematics, the factorial of n is denoted by n! and calculated by the product of integer numbers from 1 to n. For instance: In this challenge you will write a Python program that asks the user to enter a
