The results are following. ・In caramel situation, Level 3 problem is significantly more difficult for grade 2 and 3 students to solve than Level 4 problem is. ・In water situation, Level 3 problem is more difficult than Level 4 problem, but there is no statistic significance between them in grade 2 and 3. ・In number situation, Level 4 problem is more difficult than Level 3 problem.
