Students will master a total of 60 events over the course of four years (3rd-6th grades). History is a very unsystematic subject, and time is very abstract. Students need a timeline that they memorize, build on, and recite every year.
Each student should have his/her own set of flashcards for drill and practice. One side has the date and the reverse side has the event. These cards are color-coded identically to the Timeline Card on the wall.
