This is a picture of Rose [5yrs] working with the binominal cube, she did it 13 times in a row. Each time she was extremely excited and so thrilled when she completed it. It was amazing to watch her and each time she build the binominal cube she learnt something new.
Repetition is not a waste of time it is a key to the child's learning in a Montessori classroom. Often children will repeat the activity time after time until their inner need for the process of that activity has been fulfilled. Repetition helps to reinforce neural connects.
