Study Notes

Shape Sequences

  • Regular polygons have equal-length sides and equal angles
  • Examples include triangles, squares, pentagons, etc.
  • Shape sequences show patterns in mathematics
  • Number sequences can relate to shape sequences

Number Sequences

  • Number sequences are basic patterns
  • Examples include counting numbers, odd/even numbers, square/cube numbers, triangular numbers, and powers of 2
  • Number sequences can be related to each other
  • Visualising number sequences with pictures helps understanding

Stacked Shapes

  • Stacked squares sequence: Number of little squares increase in a specific pattern
  • Stacked triangles sequence: Number of little triangles increase in a specific pattern
  • Pattern in rows of triangles can help understand
  • Koch Snowflake: Sequence where each segment is replaced by smaller segments at each iteration; number segments increase in a pattern, following powers of 4)
