What does the research say? “Mathematics is an excellent vehicle for the development and improvement of a person’s intellectual competence.” Ministry of Education Singapore, 2006
What can I expect to see…in the classroom • Teaching to mastery • Concrete-pictorial-abstract model • Differentiation • Intentional progression of skills
Integrating the Concrete-Pictorial-Abstract (CPA) Model with Visualization x + 2x = 12
A Closer Look At…Bar Modeling A pictorial or diagram method of representing quantities and their relationships to solve both arithmetic and algebraic word problems. Students use rectangle blocks to represent the known and unknown: • Blocks are easily drawn and divided • Rectangles enable proportional representation and solving for the unit
Trajectory of Bar Modeling Part Part • Part/Whole • Comparison • Equal Parts
