Studies suggest that colorful ambience can immensely affect how students behave, perform and learn in a classroom. Thus, to enhance the learning performance of young school going kids, Carson-Dellosa Publishing introduces Colorful Chalkboard EZ Letters Set. The 76 pieces set includes 52 letters, 10 numbers and 14 punctuation symbols in attractive chalkboard design that can be used to create colorful decorations, messages or phrases to promote positivity in classrooms. The 4-inch letters also feature an adhesive backing, which eliminates the need for glue or masking tapes to stick the letters and also allows you to remove the letters for multiple creations.
