Bar Models and Area Models
2
Bar models and area models support students in reasoning about relationships in applications and problem solving, which is more of a conceptual approach rather than traditional procedures and computation strategies. Bar models are sometimes referred to as strip diagrams or tape diagrams and are based on Singapore math strategies. An area model is a visual representation of a multiplication, division, or factoring problem. Both types of models tap into the visual-spatial reasoning power of the human brain.
