C-R-A Model

What will students do during the representational phase of the C-R-A Model?

• Students draw pictures that represent the concrete objects previously used.

• Students will physically or virtually manipulate objects to solve a math problem.

• The teacher models the mathematics concept at a symbolic level, using only numbers, notation, and mathematical symbols.

What are the 3 levels of understanding in Math?

• Concrete

• Collaboration

• Abstract

• Representational

• Re-Teach

Check all that apply! What are the benefits of the CRA model to students?

• Provides students with a structured way to learn math concepts

• Students are able to build a better connection when moving through the levels of understanding from concrete to abstract

• Makes learning accessible to all learners (including those with math learning disabilities)

• Able to use across grade levels, from early elementary through high school

• Helps students learn concepts before learning rules
