This file contains 4 posters that provide a range of strategies for working out basic facts computations. There is a poster for addition, subtraction, multiplication and division basic facts.
The posters can be printed large for display on classroom walls or small for students to keep as reference in their mathematics books.
The four posters in this file are summary posters.
Another file in my TpT store also includes detailed posters with a poster for each strategy individually.
