Montessori Bolt Block – Three Bolt Set
Unique high quality Montessori bolt block handcrafted from cherry and maple wood, varnished with non toxic water based finishes.

This Montessori Practical Life activity is typically used in the 3-6 year old classroom. This material helps develop and strengthen hand and finger muscles of the pincer grip. It is one of the many examples of how the design of Montessori materials indirectly prepare for a future skill – in this case for holding a pencil. In addition, the practical life aspect helps a child to learn how to thread, tighten and loosen a bolt and nut!

An excellent addition to any preschool or homeschool classroom that is both intriguing to children and develops concentration.
