Schoolhouse Rock!: 3rd & 4th Grade is an educational game that teaches elements of the US curriculum for 3rd and 4th graders aged eight to ten. It is based on the Schoolhouse Rock! TV series. It comes on two discs and contains over 70 activities for the areas math, grammar, language arts, geography, science, and history. The game re-uses the plot of earlier games. The first disc features Interplanet Janet and the story from Schoolhouse Rock!: Exploration Station with eight areas based around math and science. Concepts include patterns and sequencing, equations, the human body, electricity, and more. The second disk is based around Lucky Seven Sampson with the plot from Schoolhouse Rock!: Math Rock. There the activities focus on language arts, geography and American history. Almost all of those were previously used in Schoolhouse Rock!: America Rock. The second disc then ends with the board game traditional for the series leading to rock star fame for Lucky.
