DD (5) is teaching herself simple multiplication ...we got a yahtzee game and she loves adding up all of the numbers for both of us...she is really starting to see that four - fours equals 16. Sometimes she uses really interesting approaches to figure them out..."well, I know 4 x 5 is 20 and since 4 is one less than 5 and there are four of them, I subracted 4 from 20 to get 16". I am amazed by her ability to figure things out...
