Teaching Digital Technologies to Year 7 and 8 students can be challenging.
I found transom.org resources good. The free site has lesson starters, visual aids, investigations and self marking exercises and lots of teacher resources for graphs and charts like pie chart creator. The site allows for students to work online to complete tasks about the different types of graphs and charts, has clear instructions, has a checking section and also allows for students to work through different topics in the website. The tasks link to the Curriculum which is helpful for teachers. Teachers, tutors or parents can sign up for use of this site.
