ToodleBit has create a free demonstration site. The aim of which is to provide you with the opportunity to experience ToodleBit without any financial commitment. Within Unit 1 you will have access to the first three lessons (which have been adapted to take into account you might not have the Micro:bits) which you can use with your class for free. Depending on their experience these lessons will take between 30 and 50 minutes to complete.
WARNING - ToodleBit was designed to be used with the BBC Micro:Bit and its own box of components. The kit provides the children with the hands-on experience of designing and making that makes learning to code so rewarding. These lessons can be taught without a Micro:Bit but won't be as interactive.
