Montessori tool trays and 3-part cards are popular with children who are allowed to experience real tools. This is true in both Montessori settings and in traditional classrooms. One tray at a time is provided for children to learn about individual tools such as Phillips head and flat head screwdrivers. The authenticity of the activity leads to real engagement and feelings of accomplishment. No external praise is needed with an activity is intrinsically motivating. Plus there are real word applications outside of class that children will notice.
Montessori Tool Trays
Here are a few trays set up for success. Provide only what is necessary for use. Few explanations are required once children learn how to use the tools safely. Tool instruction is provided in Montessori settings where children have access to such materials. If used in a traditional classroom, some instruction about proper use of the tool would be required. I would begin with only one tray at a time until children are demonstrating the ability to be careful and approach the materials safely. These activities also help with fine motor skills if children are needing to work on pencil grip and wrist strength.
