There is a great program called HOUR OF CODE. I used it with my students and many of them were reading far below grade level and their math skills were also very low. They were able to keep up with the program and in the beginning it was very easy for them to do the lessons. As they advance through the levels it does get a little harder but most students were able to do it without any assistance. Students also helped each other when they were stuck on a level. Overall this is a great program to learn coding.
