Nine different astronaut cards plus 2 key cards. Nineteen cards in total. I love these cards, because I have learned about each of the astronauts. I will really be working with them with the children when they have got the planets down. I am going to show them a video of the first moon walk and then we will explore each astronaut as their interest guides me. Being not so young myself, making these took me back to watching the first moonwalk at school when I was a child. A trip down memory lane. I ordered a LIFE commemorative magazine on Neil Armstrong to go with these, which has incredible pictures of life before, during and after the Apollo mission. One of my children has decided to rename himself Neil Armstrong!
