How does TouchMath use the Concrete Representational Abstract (CRA) Continuum?
CRA is a three-stage learning process where students learn through the physical manipulation of concrete objects, then through pictorial representations, and finally by solving problems using abstract notation.
The Concrete-Representational-Abstract (CRA) continuum is one foundation of the TouchMath program. CRA provides a structure for students to grasp mathematical concepts, and you’ll see it referenced in each
The CRA continuum ensures that learning progresses through three stages:
Concrete
Students use real-life physical objects to explore concepts.
- TouchNumerals
- TouchPoints
- Finger Counting
- Manipulatives
Representational
Students draw or use visual aids.
- Modeling and Drawing
- Number Lines
- Descriptive Model: describing a math happening
- Predictive Model: making a prediction
- Optimizing Model: finding the best
- Statistics and Probability Model: using data and chance
- Rating and Ranking Model: making decisions
Abstract
Students work with symbols and numbers.
- Concepts (Properties)
- Numbers
- Operations
- Calculator
This scaffolded approach:
- Solidifies understanding between different stages of learning
- Allows students to gain confidence and proficiency in math at their own pace
- Enables students to apply their knowledge to more complex mathematical problems effectively
