Montessori Services Indoor Materials for 7 Years Old

The materials come in simple designs so children can master one skill at a time. For example, sandpaper letters that show one letter at a time help children learn the letters and the sounds.

The materials can be introduced to newborn babies by showing them a black-and-white card to stimulate their senses. A pink tower can be used by a 3-year-old child to understand the concept of size.
