My girls just finished taking the Unit 4 test. We found the map part, specifically the shading of colonial regions, very difficult. I think it would have been very helpful, both to my girls filling it in and to me grading it, if the country lines had been on the blank map like they are in the Week 28 supplemental map. We also found what we believe to be a wrong answer. The north part of Morocco and the Rio de Oro are shaded as belonging to Britain instead of Spain in the answer key. The rest of the quiz was a good challenge for them and showed this mom where she needs to work with them for next year.
