Didacticalobstacleis caused by using horizontal representation strategy of place value in 2013 curriculum textbookdid not help student to interpret number from the point of view place value, so that when the student must sum the result of horizontal representation strategy, students only combine the number symbol instead of summing numbers. Another didacticalobstacleis examples and questions about place value in 2013 curriculum book are less varied that indirectly raises epistemological obstacle which lead to examples and questions are given by teacher are not varied.This finding needs to be followed up by conducting development research that can reduce learning obstacle that have been discovered
