This product is great for a quick visual of your student's understanding of any topic/lesson. They fit perfectly inside the Target Adhesive Square pockets or any pockets purchased online. They can be printed in color or on colored card stock of your choice, laminated and then cut out. Depending on the size of your pocket square there are two black square outlines to give you multiple sizes. You can also laminate them and hole punch them and use a clip ring to rotate through the colors. These have been a great addition to my classroom and have helped my class run even smoother. The addition of the "I Can Help!" cards, have also given students of an idea of who else they can ask if I am with another student!
