We have used several different brands of write and wipe cards. From Abc's to Numbers. Most of them are easily ruined by our preschoolers. They just don't stand up well with daily use by little people. We gave this brand a try. So far so good, and the preschoolers love them. They have engaged and encourage some struggling writers in our classrooms. We have included the link to purchase from amazon. We usually buy our classroom supplies from amazon and love our Prime membership. We use the cards at small group times and the children chose them during free play as well.
This is a worksheet we created to help some of our younger kids work on that fine motor grasp as well as color identification. This worksheet can be found on our product page.
