Simon found ToodleBit:

• Significantly improves attainment“Children are becoming more independent and describing the the impact their programming is having more precisely with improved use of terminology. They are also excited to access the extension challenges.”
• Moderately reduces teacher workload“The plans are clear and precise which means that I only have to spend a minimal amount of time familiarising myself with the lesson. The equipment is all neatly packaged reducing time finding resources.”
• Significantly improves teacher knowledge and skills“I had never used a Microbit before and am finding that I am enjoying learning to use them as much as the children.”
