Colour Pattern Possibilities

• 5 squares in a strip, colouring in 1 square.
• 5 squares in a strip colouring in 2 squares.
• 5 squares in a strip colouring in 3 squares.
• 5 squares in a strip colouring in 4 squares.

Looking for a Visual Pattern
4
Different Length Strips

• 2 Squares 2 combinations
• 3 Squares 6 combinations
• 4 Squares 14 combinations
• 5 Squares 28 combinations

5
Looking for a Pattern

• As the number of squares increase by 1 the number
  of colour combinations double and added 2
• 2 squares 2 combinations
• 3 squares 2x22 6 combinations
• 4 squares 6x22 14 combinations
• 5 squares 14x22 30 (we only found 28 )

6
Number of colour combinations

• 2 Squares 2 combinations
• 3 Squares 6 combinations
• 4 Squares 14 combinations
• 5 Squares 30 combinations
• 6 Squares 62 combinations

Reflections

• 48 reflecting pairs were found
• 18 strips with no reflection
• 3 squares 2 reflections 2 non reflections
• 4 squares 6 reflections 2 non reflections
• 5 squares 12 reflections 6 non reflections
• 6 squares 27 reflections 8 non reflections

Colouring of Grids

• 2x2 square grid
• 3x3 square grid
• 4x4 square grid

9
Number of grid colour combinations

• 2x2 grid 2x2 4 combinations
• 3x3 grid 3x3x3 27 combinations
• 4x4 grid 4x4x4x4 256 combinations
• Does this give valid answers?

Inclusion in E-Portfolio

• Relevant to the Curriculum and Knowledge section
• Mathematics investigations are part of school
  curriculum
• Helped further my knowledge of mathematical
  application in primary schools and basic
  mathematical procedures
