Little Star Homeschool

This afternoon Robert and I tidied the master bedroom, well...I tidied while he bounced on the bed. Later I attempted some Soduko - I've only been doing them for about a week so I am a bit slow and I get stuck. On commenting that I was indeed clueless Robert came out with the broad statement, "6 is just a 9 upside down." "yes it is" I replied adding the ubiquitous "very clever." Not to be outdone he continued, "they are both actually curly numbers. Thats all." He wandered off, I went back to my puzzle.
