My daughter's Foundations class is full of 12-year-olds who are in their final year of the program. Her Tutor has done a fantastic job at encouraging the students to sketch maps regularly. She has maintained an incentive plan for the students who sketch at least one map each week.
To organize this plan, at the beginning of the year, I purchased my daughter a sketch book. She has worked diligently this year to fill it with hand drawn maps, It was a simple way to keep us organized!
