Study Notes
Number Models
- A number model is a mathematical representation that helps visualize relationships among numbers, facilitating problem-solving.
- Number models include various types, such as number lines, arrays, and bar models, which can visually illustrate numerical concepts.
- Notably, models like verbal expressions or random symbols do not qualify as traditional number models.
Types of Number Models
- Traditional number models encompass diagrams and visual aids that represent and manipulate numbers effectively.
- Non-traditional representations that do not adhere to structured formats, such as abstract symbols or unrelated graphics, do not classify as number models.
Purpose of Number Models
- Number models are used to enhance understanding of mathematical concepts, allowing learners to manipulate and see the relationships between numbers.
- They serve to bridge concrete and abstract thinking, providing a way to visualize and solve mathematical problems.
Kristen's Educational Background
