Kids love these Lacing & Tracing activities! Colorful, heavy-duty chipboard lies flat for smoother tracing of the fun shapes that also helps build math skills as children can talk about the different shapes as they lace. Lacing helps promote good penmanship because it develops the pincer grip. The activities also increase fine-motor control, introduce problem-solving, develop concentration, and encourage quiet play. For individuals with Autism they provide precursor skills for activities such as writing and cutting. Laces are 27" long with easy-to-thread 1" tips. Pieces vary from 4" to 7" in size.
