I came across a fantastic app for students called 'Popplet' which is a tool for students to make graphic organizers to visually represent their ideas and thoughts on a particular topic. This app can be used for sharing and collaborating and is an effective pedagogical tool to use in all learning areas.
These Know-Wonder-Learn charts are an excellent resource for accessing students prior knowledge on a particular subject and brainstorming new understanding. These charts could be used for students learning in all subjects and years.
