The jump from level 1 to level 2 is too difficult. I really wish level 2 focused on time to the half hour, not on anything within 5 minute intervals. Children need to know how to tell time to the half hour before they start learning about 5, 10, 15, 20, etc. increments. Level 1 is perfect using only time to the hour. Level 2 should include time to the hour from level 1 and time to the half hour (6:30, 1:30, 11:30..) ONLY!
