Along with Addition strategy posters, I have also made Subtraction strategy posters. I found that these posters supported children's understanding and use of the different mental maths strategies for subtraction. Most children find subtraction more challenging than addition, so there was a definite need for visual support during our whole class Number Talks. These posters helped all of the children more easily access their classmates' mathematical thinking (although it's important to remember that in Number Talks, the best resources your class has for supporting and enhancing their strategy understanding is you, as their teacher).
The posters are differentiated, and I used different ones, depending on the stage I was teaching, as well as the individual children in each class. Occasionally, I would display 2 different versions of the posters. All of the strategies are essentially the same, and they are presented in the same format - I have just used different equations (easier/more challenging) to illustrate each strategy.
These posters coordinate well with the addition posters - I've used a different background, and the word 'Subtraction' is in red at the bottom of each of these posters, to help your children easily identify whether the poster is addition or subtraction, when they are looking at them for visual support.
If you click on each picture above, you will be taken to Teachers Pay Teachers, where you'll be able to download the files you are interested in. All of the posters are free. I hope you find them useful and that they encourage you to establish Number Talks as part of your own classroom routine!
