Books for a math teacher who just got her specialist degree! I had a time with this cake....my father-in-law ate my apple that was carved out of cake thinking that I had discarded it-so I had to go buy some RKT FAST! Than I realized after gluing down the letters that I had spelled the joke wrong! In a house of math nerds, I would have been so embarrassed! Thank goodness for sisters and spell check! I think these books came out alright! I have never done a book and I learned a lot from the first one to the second! Thank you for looking!
