This file contains 4 posters that provide a range of strategies for working out computations for each of the 4 operations. There is a poster for addition, subtraction, multiplication and division computation strategies plus an introduction slide.
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.
Other files in my TpT store also includes detailed posters for computation strategies and basic fact strategies with summary posters and posters for each strategy individually.
