These 12 rectangles each have a perimeter of 24cm or 28cm, making them perfect for a sorting activity. They are each included as separate JPEG images for maximum flexiblility for your teaching presentations and worksheets. There is also a jpeg of the six rectangles with a perimeter of 24cm together, and the six rectangles with a perimeter of 28cm together, as well as a jpeg of all of the rectangles. I have also included the word document so that you can easily tinker with the rectangles if you need to. I am new to sharing my resources on TES so please let me know if you have any issues as I will rectify as soon as possible. Thank you for your interest in my rectangles :)
