When I placed the pink tower on the table I wanted the children to learn the order through trial and error. The mums (although I did tell them beforehand) just couldn’t resist intervening.
This is a perfect example of why we as teachers should not intervene at the first signs of failure. Let the child discover their error and learn from it.
Children don’t know that fire burns until they feel the heat of a flame, or that salt tastes awful in large quantities until they have a spoon full.
Allow the child to make his/her mistakes and the journey of learning will be enriched immensely.
