Early Logo
An early version of the logo for JumpStart 5th Grade exists in the files of JumpStart Math for Second Graders. The early logo is very similar to the logos for the original releases of JumpStart Adventures 3rd Grade: Mystery Mountain and JumpStart Adventures 4th Grade: Haunted Island. Sometime in 1997, JumpStart restyled the logo for the 3rd-6th grade games, and the final release of JumpStart 5th Grade uses the newer style.

Another early version of the logo appeared in KnowledgeLand. This version uses the standard logo design from the earlier preschool to second grade games, which features a ruler instead of a metal bar with bolts.
