Letter-Sleuth was created for my son's 4th birthday party (during the holidays) because I couldn’t find a game for the kids to play at any retail store.
The kids had so much fun they asked to play it again & again.
Afterwards, I brought it to the 1st grade spring party activity that I volunteered for.
The Teacher loved it because it had many important elements for early education.
Since then, Educators have helped develop the content for STEM categories.
