I've read lots of blogs recently about quiet critters as a behaviour management tool. For anyone not aware of what these are, they're basically pom pom balls with googly eyes and foam feet and they don't like noise! They only come out of their soundproof jar when it's quiet and sit next to children who are quiet. At the end of each week, each child on the table with the most critters, wins a prize. My question is, what are your thoughts on using quiet critters in lower ks2? Do you think they would work or are they more ks1?
