These sturdy foam lowercase magnetic letters are custom-designed for early literacy and Reading Recovery teachers. The entire letter is magnetic, so it won’t slip and slide. They’re perfect for individual and small-group instruction. For working with a group of six students, we recommend four sets of lowercase and one set of uppercase letters. Magnetic trays are sold separately. This set includes a range of multiples of every letter. Each set will include TWO complete alphabets and a large number of extra for high-frequency letters.
