I had a 7th grade student with PDD-NOS who was tested at a kindergarten math level. He struggled with graphing. I taught him to use Excel on the computer to generate graphs and gave him a standing direction to use it whenever we had a graph to complete. The top photo below shows a warm-up problem (“do now”) his class was given. A classmate’s artifact is shown at the right. 
My student walked in, saw the assignment was a graph problem and jumped on the computer. Below is the graph he created on his own.
