About Adding Doubles
Addition is the process of combining two or more quantities to find a total. It is one of the four fundamental operations of arithmetic and the one children typically learn first. These worksheets progress from concrete representations (counting pictures and objects) to abstract number sentences, building both conceptual understanding and computational fluency.
Doubles facts are among the easiest to memorize and serve as anchor facts for solving nearby addition problems quickly.
