This file contains 70 posters that provide a range of strategies for working out basic facts computations and computations for operations beyond basic facts. There is a poster for addition, subtraction, multiplication and division.
This file contains summary posters and a poster for each strategy individually for both basic facts and operation strategies.
This file contains all the posters I have made for computation which I also have available as separate files in my TpT store. (This file is better value)
The posters can be printed large for display on classroom walls or small for students to keep as reference in their mathematics books.
Other files in my TpT store contain smaller sets of these posters e.g. just basic facts or just operations beyond basic fact summary posters.
