These posters have been extremely successful with year 4 students all the way up to my year 10 Mathematics students.
There are 11 all together; 2 copies with borders and 1 plain so you can add your own taste or style to it.
They have enabled students to complete their work successfully and independently with the support of the posters.
Having the shape visually and identifying which of the sides are the width, length, height etc. gives students the independence to attempt the work themselves before they ask for help.
The posters have the rule written in words and the summarised rule using pronumerals which allows students to see how the rule is shortened.
If you have a suggestion for any other posters, please let me know and I will update these! :)
