Here is another easy to make Montessori practical life activity. You will need a clean bath mat and some marbles. You can purchase these items at a dollar store or your favorite discount store.
Cut the bath mat into a shape. The shapes can be triangular, make what ever works best with your type of bath mat. The mat will be used with the suction cups face up. Provide as many marbles as you have suction cups. Present the same way you would the soap holder and beads activity. Your child can do this activity with fingers first, and a pilers or tweezer for a more advanced extension.
