number sense
Feeling for quantities
Number sense is an intuitive grasp of how numbers work—their relative sizes, relationships, and behavior in operations.
Someone with strong number sense recognizes that 47 + 38 is close to 85 without calculating, or that dividing by a fraction makes things larger.
She has good number sense and catches arithmetic errors immediately.
The term appears most often in educational contexts, describing a foundational mathematical fluency distinct from memorized procedures.
