Study Notes
Number Patterns
- Sequences of numbers following a rule or formula are called number patterns.
- Arithmetic sequences involve adding or subtracting a common difference between consecutive terms.
- Geometric sequences involve multiplying or dividing by a common ratio between consecutive terms.
- Examples of number patterns include:
- 2, 4, 6, 8... (arithmetic, common difference is 2)
- 3, 6, 12, 24... (geometric, common ratio is 2)
- 1, 4, 9, 16... (squares of consecutive integers, follows a specific mathematical pattern)
- Understanding number patterns helps predict future terms in the sequence.
- Recognizing patterns allows for the derivation of the formulas that describe them.
Shape Patterns
- Shape patterns involve repeating or transforming shapes according to a rule or formula.
- One shape or group of shapes may be repeated in a sequence, or shapes may be changed in size, position, or orientation.
- Examples of geometric patterns include:
- Tessellations (repeating shapes to cover a surface without gaps or overlaps)
- Fractal patterns, which have self-similar structures at different scales (e.g., the Mandelbrot set)
- Spiral patterns, which appear in nature (e.g., nautilus shells)
- Understanding shape patterns frequently involves translating the pattern into an algebraic description of the relationships between the elements and properties of the shapes.
- Determining the overall characteristics of the patterns can be used to predict future elements in the sequence.
- Symmetry and transformations (rotations, reflections, translations) play a role in many shape patterns.
Relationships Between Number and Shape Patterns
- Number patterns can often be visualized using shape patterns. For instance, the triangular numbers can be represented by arranging dots into triangles, or Pascal's Triangle, which reveals patterns in binomial coefficients, can also be visually displayed.
- Geometric sequences can be represented by sequences of shapes, where the size or area of the shapes increases or decreases by a common ratio.
- Recognizing both number and shape patterns often helps solidify understanding of mathematical principles and concepts by providing a tangible, visual representation.
- The discovery of particular patterns in numbers and shapes can lead to the development of new mathematical concepts and tools.
