Is it worth the risk?
I have been working with a school, in Kingston, recently who have decided to start using real tools such as hammers, with the children. They have some concerns around this, one of them being how to introduce this to parents given the fact that some have already complained about children being outside when it is cold!
I have always ensured that risk-taking was addressed at all new parent meetings, particularly when showing prospective parents around the school! Forewarned is forearmed as they say! During the tour of the school, I would point out children using real tools, show them how safely and sensibly they were using them and explain how they were introduced but, more importantly, I would explain the benefits. The reasons why children needed these opportunities.
