Sensorial Activities focus on and allow the child to refine each of the senses. They include specifically designed materials that isolate just one quality. As such, sensorial activities refine fine motor skills, visual and auditory senses, and develop coordination and the ability to order and classify. In particular, sensorial activities focus on either sight (visual), touch (tactile), smell (olfactory), taste (gustatory), sound (auditory), and stereognostic (kinesthetic) senses.

Many sensorial materials, such as a Pink Tower, Red Rods and sensory Tactile Boards are in fact a precursor to numeracy work. A child then transitions to number rods, sandpaper numbers, number boards, spindle box, number tiles, beads, and games. Each exercise builds upon another and the child gradually moves from concrete to abstract areas such as place value, addition, subtraction, multiplication, and fractions.

In a Montessori environment, although not a "core subject," arts and crafts provide children with a hands-on way to express creativity and develop fine motor skills, fostering a sense of independence and self-expression. Through self-guided exploration of various materials, children cultivate their imagination and build confidence, nurturing their cognitive and emotional growth.
