Luma World Writer Macy Educational Game-Based Math Flash Cards with a Fun Magic Glass to View Hidden Answers for Ages 9+ Years to Learn Grade 4 Geometry, Shapes and Patterns, Set of 50 Cards

This is such a fun resource for my homeschool kid! My 9 year old is going into 4th grade, so these are some concepts that she has learned or is beginning to learn and the "magic glass" offers a fun touch to finding out the right answer. Being able to play with that adds to the joy of figuring out the problem. The answers are not completely invisible without the glass, but they are pretty obscured to the naked eye! She also had fun creating her own hidden messages with markers and using the tool to have others decode! Super fun.
